ABSTRACT

Abstract Background Post-spinal anesthesia hypotension is of common occurrence, and it hampers tissue perfusion. Several preoperative factors determine patient susceptibility to hypotension. This study aimed to assess the effectiveness of the Inferior Vena Cava Collapsibility Index (IVCCI) for predicting intraoperative hypotension. Methods One hundred twenty-nine adult patients who were scheduled for elective surgical procedures after administration of spinal (intrathecal) anesthesia were included in the study. Ultrasound evaluation of the Inferior Vena Cava (IVC) was done in the preoperative area, and the patients were shifted to the Operating Room (OR) for spinal anesthesia. An independent observer recorded the change in blood pressure after spinal anesthesia inside the OR. Results Twenty-five patients developed hypotension (19.37%). Baseline systolic blood pressure and mean blood pressures were statistically higher in those patients who developed hypotension (p= 0.001). The logistic regression analysis for IVCCI and the incidence of hypotension showed r2 of 0.025. Receiver Operating Characteristic (ROC) curve analysis demonstrated the Area Under the Curve (AUC) of 0.467 (95% Confidence Interval, 0.338 to 0.597; p= 0.615). Conclusions Preoperative evaluation of IVCCI is not a good predictor for the occurrence of hypotension after spinal anesthesia.

ABSTRACT

Abstract Background: Postoperative nausea and vomiting (PONV) are major complications after general anesthesia. Although various pathways are involved in triggering PONV, hypotension plays an important role. We hypothesized that intraoperative hypotension during general anesthesia might be responsible for the incidence of PONV. Methods: We retrospectively investigated patients who underwent thyroidectomy. The initial blood pressure measured before induction of anesthesia was used as the baseline value. The systolic blood pressure measured during the operation from the start to the end of anesthesia was extracted from anesthetic records. The time integral value when the measured systolic blood pressure fell below the baseline value was calculated as area under the curve (AUC) of s100%. Results: There were 247 eligible cases. Eighty-eight patients (35.6%) had PONV. There was no difference in patient background between the patients with or without PONV. Univariate analysis showed that the total intravenous anesthesia (TIVA) (p = 0.02), smoking history (p = 0.02), and AUC-s100% (p = 0.006) were significantly associated with PONV. Multiple logistic regression analysis revealed that TIVA (OR: 0.54, 95% CI: 0.29-0.99), smoking history (OR: 0.60, 95% CI: 0.37-0.96), and AUC-s100% (OR: 1.006, 95% CI: 1.0-1.01) were significantly associated with PONV. Conclusion: Intraoperative hypotension evaluated by AUC-s100% was related to PONV in thyroidectomy.

ABSTRACT

OBJECTIVE@#Current clinical evidence on the effects of home blood pressure telemonitoring (HBPT) on improving blood pressure control comes entirely from developed countries. Thus, we performed this randomized controlled trial to evaluate whether HBPT plus support (patient education and clinician remote hypertension management) improves blood pressure control more than usual care (UC) in the Chinese population.@*METHODS@#This single-center, randomized controlled study was conducted in Beijing, China. Patients aged 30-75 years were eligible for enrolment if they had blood pressure [systolic (SBP) ≥ 140 mmHg and/or diastolic (DBP) ≥ 90 mmHg; or SBP ≥ 130 mmHg and/or DBP ≥ 80 mmHg with diabetes]. We recruited 190 patients randomized to either the HBPT or the UC groups for 12 weeks. The primary endpoints were blood pressure reduction and the proportion of patients achieving the target blood pressure.@*RESULTS@#Totally, 172 patients completed the study, the HBPT plus support group ( n = 84), and the UC group ( n = 88). Patients in the plus support group showed a greater reduction in mean ambulatory blood pressure than those in the UC group. The plus support group had a significantly higher proportion of patients who achieved the target blood pressure and maintained a dipper blood pressure pattern at the 12th week of follow-up. Additionally, the patients in the plus support group showed lower blood pressure variability and higher drug adherence than those in the UC group.@*CONCLUSION@#HBPT plus additional support results in greater blood pressure reduction, better blood pressure control, a higher proportion of dipper blood pressure patterns, lower blood pressure variability, and higher drug adherence than UC. The development of telemedicine may be the cornerstone of hypertension management in primary care.

ABSTRACT

OBJECTIVES@#With the rapid development of aging population, the number of elderly patients undergoing posterior lumbar spine surgery continues to increase. Lumbar spine surgery could cause moderate to severe postoperative pain, and the conventional opioid-based analgesia techniques have many side effects, which are barriers to the recovery after surgery of the elderly. Previous studies have demonstrated that erector spinae plane block (ESPB) could bring about favorable analgesia in spinal surgery. As far as the elderly are concerned, the analgesic and recovery effects of ESPB on posterior lumbar spine surgery are not completely clear. This study aims to observe the effects of bilateral ESPB on elderly patients undergoing posterior lumbar spine surgery, and to improve the anesthesia techniques.@*METHODS@#A total of 70 elderly patients of both sex, who were selected from May 2020 to November 2021, scheduled for elective posterior lumbar spine surgery, and in the age of 60-79 years, with American Society of Anesthesiologists class Ⅱ-Ⅲ, were divided into a ESPB group and a control (C) group using a random number table method, with 35 patients each. Before general anesthesia induction, 20 mL 0.4% ropivacaine was injected to the transverse process of L3 or L4 bilaterally in the ESPB group and only saline in the C group. The score of Numerical Rating Scale (NRS) indicating pain at rest and on movement within 48 h after operation, time of first patient control analgesia (PCA), cumulative consumptions of sufentanil within 48 hours, Leeds Sleep Evaluation Questionnaire (LSEQ) scores on the morning of day 1 and day 2 after operation, Quality of Recovery-15 (QoR-15) scores at 24 and 48 h after operation, full diet intake times, perioperative adverse reactions such as intraoperative hypotension, postoperative dizziness, nausea, vomiting, and constipation were compared between the 2 groups.@*RESULTS@#A total of 70 patients were enrolled and 62 subjects completed the study, including 32 in the ESPB group and 30 in the C group. Compared with the C group, the postoperative NRS scores at rest at 2, 4, 6, and 12 h and on movementat at 2, 4, and 6 h were lower, time of first PCA was later, sufentanil consumptions were significantly decreased during 0-12 h and 12-24 h after operation, LSEQ scores on the morning of day 1 and QoR-15 scores at 24 and 48 h after operation were higher, full diet intakes achieved earlier in the ESPB group (all P<0.05). There were no significant differences in the incidences of intraoperative hypotension, postoperative dizziness, nausea, vomiting, and constipation between the 2 groups (all P>0.05).@*CONCLUSIONS@#Providing favorable analgesic effects with reduced opioids consumption, bilateral ESPB for posterior lumbar spine surgery in the elderly patients could also improve postoperative sleep quality, promote gastrointestinal functional restoration, and enhance recovery with few adverse reactions.

ABSTRACT

Abstract Introduction and objectives Multimodal Analgesia (MMA) has shown promising results in postoperative outcomes across a broad spectrum of surgeries, including bariatric surgery. We compared the analgesic effect immediately after Laparoscopic Bariatric Surgery (LBS) of the combined effect of MMA and methadone against two techniques that were based mainly on the use of high-potency medium-acting opioids. Methods Two hundred seventy-one patients were retrospectively reviewed. The primary outcome was postoperative pain score > 3/10 measured by the Verbal Numeric Scale (VNS) during the Postanesthetic Care Unit (PACU) stay. The three protocols of intraoperative analgesia were: (P1) sufentanil at anesthetic induction followed by remifentanil infusion; (P2) sufentanil at induction followed by dexmedetomidine infusion; and (P3) remifentanil at induction followed by MMA including dexmedetomidine, magnesium, lidocaine, and methadone. Only P1 and P2 patients received morphine toward the end of surgery. Poisson regression was used to adjust confounding factors and calculate Prevalence Ratio (PR). Results Postoperative VNS > 3 was recorded in 135 (49.81%) patients, of which 93 (68.89%) were subjected to P1, 25 (18.56%) to P2, and 17 (12.59%) to P3. In the final adjusted model, both anesthetic techniques (P3) (PR = 0.10; 95% CI [0.03-0.28]), and (P2) (PR = 0.42%; 95% CI [0.20-0.90]) were associated with lower occurrence of VNS > 3, whereas age range 20-29 was associated to higher occurrence of VNS > 3 (PR = 3.21; 95% CI [1.22-8.44]) in PACU. Postoperative Nausea and Vomiting (PONV) was distributed as follows: (P1) 20.3%, (P2) 31.25% and (P3) 6.77%; (P3 < P1, P2; p< 0.05). Intraoperative hypotension occurred more often in P3 (39%) compared to P2 (20.31%) and P1 (17.46%) (p< 0.05). Conclusion MMA + methadone was associated with higher incidence of intraoperative hypotension and lower incidence of moderate/severe pain in PACU after LBS.

ABSTRACT

INTRODUCCIÓN. La crisis suprarrenal se refiere a la insuficiencia suprarrenal aguda; la cual es un trastorno en el que la corteza adrenal no produce suficientes hormonas esteroides (en especial cortisol) para satisfacer las demandas del cuerpo, de acuerdo al mecanismo fisiopatológico se la puede clasificar como primaria, secundaria y terciaria, siendo más común en pacientes con insuficiencia suprarrenal primaria. Es una emergencia potencialmente mortal que requiere tratamiento inmediato. OBJETIVO. Establecer una estrategia de prevención y tratamiento de la crisis suprarrenal, así como la farmacoterapia ideal y sus alternativas válidas. MATERIAL Y MÉTODOS. Se realizó una revisión bibliográfica en varias revistas virtuales de alto carácter científico como Cochrane Library, Cochrane Systematic Reviews Database, MEDLINE a través de PubMed y ClinicalTrial.gov. Se seleccionaron revisiones sistemáticas con o sin metaanálisis, ensayos clínicos y recomendaciones de expertos relacionados con prevención y tratamiento de crisis suprarrenal en general. RESULTADOS. Se obtuvieron 1819 resultados, de los cuales se seleccionaron 20 artículos con mayor validez y replicabilidad en el medio para establecer un protocolo unificado de actuación. CONCLUSIÓN. El objetivo de la terapia es el tratamiento de la hipotensión y reversión de las anomalías electrolíticas y de la deficiencia de cortisol. Se deben infundir por vía intravenosa grandes volúmenes (1 a 3 litros) de solución salina al 0,9% o dextrosa al 5% en solución salina al 0,9% y la administración de hidrocortisona (bolo de 100 mg), seguido de 50 mg cada 6 horas (o 200 mg / 24 horas como infusión continua durante las primeras 24 horas). Si no se dispone de hidrocortisona, las alternativas incluyen prednisolona, prednisona y dexametasona.


INTRODUCTION. Adrenal crisis refers to acute adrenal insufficiency; which is a disorder in which the adrenal cortex does not produce enough steroid hormones (especially cortisol) to meet the body's demands, according to the pathophysiological mechanism it can be classified as primary, secondary and tertiary, being more common in patients with primary adrenal insufficiency. It is a life-threatening emergency that requires immediate treatment. OBJECTIVE. To establish a strategy for the prevention and treatment of adrenal crisis, as well as the ideal pharmacotherapy and its valid alternatives. MATERIAL AND METHODS. A literature review was performed in several highly scientific virtual journals such as Cochrane Library, Cochrane Systematic Reviews Database, MEDLINE through PubMed and ClinicalTrial.gov. Systematic reviews with or without meta-analysis, clinical trials and expert recommendations related to prevention and treatment of adrenal crisis in general were selected. RESULTS. A total of 1819 results were obtained, from which 20 articles with greater validity and replicability in the setting were selected to establish a unified protocol for action. CONCLUSIONS. The aim of therapy is the treatment of hypotension and reversal of electrolyte abnormalities and cortisol deficiency. Large volumes (1 to 3 liters) of 0.9% saline or 5% dextrose in 0.9% saline and administration of hydrocortisone (100 mg bolus), followed by 50 mg every 6 hours (or 200 mg / 24 hours as a continuous infusion for the first 24 hours) should be infused intravenously. If hydrocortisone is not available, alternatives include prednisolone, prednisone, and dexamethasone.

ABSTRACT

Obstetric spinal anaesthesia is routinely used in South African district hospitals for caesarean sections, providing better maternal and neonatal outcomes than general anaesthesia in appropriate patients. However, practitioners providing anaesthesia in this context are usually generalists who practise anaesthesia infrequently and may be unfamiliar with dealing with complications of spinal anaesthesia or with conversion from spinal to general anaesthesia. This is compounded by challenges with infrastructure, shortages of equipment and sundries and a lack of context-sensitive guidelines and support from specialised anaesthetic services for district hospitals. This continuous professional development (CPD) article aims to provide guidance with respect to several key areas related to obstetric spinal anaesthesia, and to address common concerns and queries. We stress that good clinical practice is essential to avoid predictable, common complications, and hence a thorough preoperative preparation is essential. We further discuss clinical indications for preoperative blood testing, spinal needle choice, the use of isobaric bupivacaine, spinal hypotension, failed or partial spinal block and pain during the caesarean section. Where possible, relevant local and international guidelines are referenced for further reading and guidance, and a link to a presentation of this topic is provided.Keywords: anaesthesia; resource-limited settings; emergency surgery; obstetric spinal anaesthesia; anaesthetic complications; caesarean section.

ABSTRACT

OBJECTIVE@#To study the risk factors of stroke after of elderly patients with hip fracture after operation.@*METHODS@#From March 2012 to June 2017, 500 elderly patients with hip fracture who underwent hip replacement were selected, including 286 males and 214 females, aged from 60 to 76 years old with an average of (68.49±11.85) years. They were divided into stroke group with 30 cases and control group with 470 cases according to the occurrence of acute stroke within two weeks after operation. The general data and serum contents of cytokines IL-1, IL-6, IL-10 and TNF-α were compared between the two groups. The overall survival of the two groups were followed up.@*RESULTS@#There was no significant difference in sex, age, anesthesia method, operation time, intraoperative blood loss, preoperative IL-1, IL-6, IL-10 and TNF-α contenta between stroke group and control group(P>0.05). The prevalence of hypertension, diabetes mellitus, atrial fibrillation, intraoperative hypotension, IL-1, IL-6, IL-10 and TNF-α contenta 1 day and 3 days after operation of stroke group were significantly higher than control group(P<0.05);up to the date of follow-up, the cumulative survival rate of stroke patients were significantly lower than those of the control group(P<0.05). Logistic regression analysis showed that intraoperative hypotension, elevated contents of serum IL-1 and TNF-α at 1 and 3 days after operation were risk factors for acute stroke.@*CONCLUSION@#Postoperative stroke in elderly patients with hip fracture affects the prognosis of the disease. The increase of inflammatory cytokines IL-1 and TNF-α after operation is an independent risk factor for stroke.

ABSTRACT

Objective: To summarize the clinical characteristics of patients with Takotsubo syndrome (TTS) from China and compare these features with patients from Europe/North America. Methods: We reviewed case reports published between 1990 and 2020 with the key words of "Takotsubo syndrome" "stress cardiomyopathy" "apical balloon syndrome" and "broken heart syndrome", in Wanfang, CNKI, Pubmed and Web of Science databases, and 1 294 articles were identified, including 128 articles reporting 163 cases in China and 1 166 articles reporting 1 256 cases in Europe/North America. The characteristics of demographics, triggers, symptoms, electrocardiogram, echocardiography, left ventriculogram,coronary angiography, treatment and prognosis were analyzed and compared between Chinese and European/North American cases. Results: A total of 1 294 articles (1 419 cases: 163 from China, 1 256 from Europe/North America) were included in the final analysis. The characteristics of Chinese cases included: (1) demographic:the age was (59.6±16.9) years, which was similar with that of European/North American ((59.7±17.4) years, P=0.90), and female accounting for 78.5% (128/163), which was lower than that of European/North American (85.4% (1 073/1 256), P=0.02). (2) Triggers:mental triggers accounted for 48.5% (79/163), physical triggers accounted for 43.6% (71/163), and no triggers accounted for 7.9% (13/163), respectively. Compared with Europe/North America, the ratio of patients with mental triggers was higher in China, while the ratio of patients with physical triggers and no triggers was lower (P<0.05). (3) Symptoms: chest pain (52.8% (86/163)), chest tightness (35.0% (57/163)), shortness of breath (33.1% (54/163)), dizziness (16.0% (26/163)), sweating (15.3% (25/163)), palpitations (12.3% (20/163)), syncope (9.2% (15/163)) abdominal pain/diarrhea (8.6% (14/163)), hypotension (7.4% (12/163)), and fatigue (1.2% (2/163)) were illustrated in sequence. Compared with patients in Europe/North America, the ratio of patients with chest tightness, dizziness, sweating, palpitations, abdominal pain/diarrhea was higher in Chinese patients, while the ratio of patients with hypotension was lower in Chinese patients (P<0.05). (4) Electrocardiogram: main manifestations were myocardial ischemia symptoms, such as ST-segment elevation (63.8% (104/163)), T wave inversion (46.0% (75/163)), ST-segment depression (8.6% (14/163)). Compared with European/North American, the ratio of patients with ST-segment elevation, T wave inversion, and atrioventricular block was higher in Chinese patients (P<0.05). (5) Echocardiography and imaging:apical dyskinesia (59.5% (97/163)) and apical/left ventricular bulbar dilation (36.2%(59/163)) dominated the echocardiography findings. Compared with European/North American, the ratio of patients with apical dyskinesia, apical/left ventricular bulbar dilation, and mitral regurgitation was higher in Chinese patients, while the ratio of patients with dyskinesia in other parts and left ventricular ejection fraction<50% was lower in Chinese patients (P<0.05). Left ventricular angiography showed 36.2% (59/163) of apical dyskinesia in Chinese patients, which was higher than that reported in European/North American patients, and 38.7% (63/163) of apical/left ventricular bulbar dilation was reported in Chinese patients, which was similar to that reported in European/North American patients. Coronary angiography showed percent of no stenosis or stenosis less than 50% was 87.1% (142/163), which was similar to that reported in European/North American patients (P>0.05). The typical type of TTS accounted for 96.3% (157/163), which was significantly higher than that reported in European/ American patients, while the ratio of basal type and midventricular type was lower (P<0.01). (6) Treatment and prognosis:the applied drugs in China were listed in order as following, β-blockers (41.1% (67/163)), antiplatelet agents (37.4%(61/163)), ACEI/ARB (36.2%(59/163)), anticoagulants (27.0%(44/163)), diuretics (19.6% (32/163)), etc. Compared with Europe/North America, the ratio of antiplatelet agents, anticoagulants, statins, diuretics, and nitrates use was higher in China (P<0.05), while the use of oxygen therapy and IABP was similar (P>0.05). The hospital mortality in China was 5.5% (9/163), during 1-year follow-up the recurrence rate was 3.7% (6/163) and the mortality was 0. The prognosis was similar with that in Europe/North America. Conclusions: Compared with TTS cases in Europe/North America, TTS cases in China also occur usually in middle-aged and elderly women, most of whom have mental/physical triggers and typical imaging manifestations, followed by a low hospital mortality rate and recurrence rate.

ABSTRACT

OBJECTIVE@#To explore the effectiveness and feasibility of dexamethasone combined with oxybuprocaine hydrochloride gel on the prevention of postoperative sore throat after nasal endoscopy.@*METHODS@#In the study, 60 patients with American Society of Anesthesiologist (ASA) physical statuses Ⅰ to Ⅱ, aged 18 to 72 years, scheduled for elective nasal endoscope surgery under general anesthesia requiring endotracheal intubation were randomly divided into dexamethasone combined with oxybuprocaine hydrochloride gel group (G group, n=30) and control group (C group, n=30). The patients in the G group received dexamethasone 0.1 mg/kg before induction and the oxybuprocaine gel was applied to the endotracheal catheter cuff and the front end within 15 cm. The patients in the C group received the same dose of saline and the saline was applied to the endotracheal catheter cuff and the front end within 15 cm. Then, all the patients in the two groups received the same induction and anesthesia maintainance. The operation time, anesthesia time, emergence time, extubation time and departure time were recorded. The intraoperative infusion volume, blood loss volume, propofol, remifentanil, rocuronium dosage were also recorded. The adverse reactions such as intraoperative hypotension, bradycardia and postoperative agitation were recorded. The postoperative sore throat score was recorded at the end of operation and 4 h, 8 h, 12 h, and 24 h after operation.@*RESULTS@#Compared with the C group, the emergence time [(8.4±3.9) min vs. (10.8±4.7) min], extubation time [(8.8±3.7) min vs. (11.9±4.8) min], and departure time [(20.0±5.3) min vs. (23.0±5.8) min] were significantly shorter, and the propofol dosage [(11.8±1.8) mg/kg vs. (15.9±4.6) mg/kg], remifentanil dosage [(10.9±4.7) μg/kg vs. (14.1±3.6) μg/kg] were significantly less in the G group, and there was no difference of rocuronium dosage in the two groups. Compared with the C group the incidence of intraoperative hypotension [10%(3/30) vs. 30%(9/30)], bradycardia [16.7%(5/30) vs. 20%(6/30)] and postoperative agitation [6.7%(2/30) vs. 23.3%(7/30)] were significantly lower in the C group. The postoperative sore throat score at the end of operation, 4 h, 8 h, 12 h and 24 h after operation in the G group were significantly lower than in the C group respectively [0 (0, 1) vs. 1 (1, 2), 0 (0, 0) vs. 1 (1, 2), 0 (0, 0) vs. 1 (1, 2), 0 (0, 0) vs. 1 (0.75, 1), 0 (0, 0) vs. 1 (0, 1)].@*CONCLUSION@#Dexamethasone combined with oxybuprocaine hydrochloride gel was effective and feasible on the prevention of postoperative sore throat after nasal endoscopy.

ABSTRACT

OBJECTIVES@#Postoperative delirium (POD) and postoperative cognitive dysfunction (POCD) are common operative neurocognitive disorders, which places a heavy burden on patients, families and society. Therefore, it is very important to search for preventive drugs. Previous studies have demonstrated that perioperative use of dexmedetomidine resulted in a decrease the incidence of POD and POCD. But the specific effect of dexmedetomidine on elderly patients undergoing hepatic lobectomy and its potential mechanism are not clear. This study aims to evaluate the efficacy of intraoperative use of dexmedetomidine on preventing POD and POCD in elderly patients undergoing hepatic lobectomy and the influence on the balance between proinflammation and anti-inflammation.@*METHODS@#This trial was designed as a single-center, prospective, randomized, controlled study. One hundred and twenty hospitalized patients from January 2019 to December 2020, aged 60-80 years old with American Society of Anesthesiologists (ASA) II-III and scheduled for hepatic lobectomy, were randomly allocated into 3 groups (n=40) using a random number table: A C group, a Dex1 group, and a Dex2 group. After anesthesia induction, saline in the C group, dexmedetomidine [0.3 μg/(kg·h)] in the Dex1 group, and dexmedetomidine [0.6 μg/(kg·h)] in the Dex2 group were infused until the end of operation. The incidences of hypotension and bradycardia were compared among the 3 groups. Confusion Assessment Method (CAM) for assessing POD and Mini Mental State Examination (MMSE) for evaluating POCD were recorded and venous blood samples were obtained for the determination of neuron specific enolase (NSE), TNF-α, IL-1β, and IL-10 at the different time below: the time before anesthesia (T0), and the first day (T1), the third day (T2), the fifth day (T3), and the seventh day (T4) after operation.@*RESULTS@#Compared with the C group, the incidences of bradycardia in the Dex1 group or the Dex2 group increased (both P<0.05) and there was no difference in hypotension in the Dex1 group or the Dex2 group (both P>0.05). The incidences of POD in the C group, the Dex1 group, and the Dex2 group were 22.5%, 5.0%, and 7.5%, respectively. The incidences of POD in the Dex1 group or the Dex2 group declined significantly as compared to the C group (both P<0.05). However, there is no difference in the incidence of POD between the Dex1 group and the Dex2 group (P>0.05). The incidences of POCD in the C group, the Dex1 group, and the Dex2 group were 30.0%, 12.5%, and 10.0%, respectively. The incidences of POCD in the Dex1 group and the Dex2 group declined significantly as compared to the C group (both P<0.05). And no obvious difference was seen in the incidence of POCD in the Dex1 group and the Dex2 group (P>0.05). Compared with the C group, the level of TNF-α and IL-1β decreased and the level of IL-10 increased at each time points (from T1 to T4) in the Dex1 group and the Dex2 group (all P<0.05). Compared with the Dex1 group, the level of IL-1β at T2 and IL-10 from T1 to T3 elevated in the Dex2 group (all P<0.05). Compared with the T0, the concentrations of NSE in C group at each time points (from T1 to T4) and in the Dex1 group and the Dex2 group from T1 to T3 increased (all P<0.05). Compared with the C group, the level of NSE decreased from T1 to T4 in the Dex1 group and the Dex2 group (all P<0.05).@*CONCLUSIONS@#Intraoperative dexmedetomidine infusion can reduce the incidence of POCD and POD in elderly patients undergoing hepatic lobectomy, and the protective mechanism appears to involve the down-regulation of TNF-α and IL-1β and upregulation of IL-10 expression, which lead to rebalance between proinflammation and anti-inflammation.

ABSTRACT

Abstract Background: The cuneiform nucleus is located in the center of the circuit that mediates autonomic responses to stress. Hemorrhagic hypotension leads to chemoreceptor anoxia, which consequently results in the reduction of baroreceptor discharge and stimulation of the chemoreceptor. Objective: Using the single-unit recording technique, the neuronal activities of the cuneiform nucleus were investigated in hypotensive states induced by hemorrhage and administration of an anti-hypertensive drug (hydralazine). Methods: Thirty male rats were divided into the control, hemorrhage, and hydralazine groups. The femoral artery was cannulated for the recording of cardiovascular responses, including systolic blood pressure, mean arterial pressure, and heart rate. Hydralazine was administered via tail vein. The single-unit recording was performed from the cuneiform nucleus. Results: The maximal systolic blood pressure and the mean arterial pressure significantly decreased and heart rate significantly increased after the application of hydralazine as well as the following hemorrhage compared to the control group. Hypotension significantly increased the firing rate of the cuneiform nucleus in both the hemorrhage and hydralazine groups compared to the control group. Conclusions: The present data indicate that the cuneiform nucleus activities following hypotension may play a crucial role in blood vessels and vasomotor tone.


RESUMO Antecedentes: O núcleo cuneiforme está localizado no centro do circuito que media as respostas autonômicas ao estresse. A hipotensão hemorrágica leva à anóxia dos quimiorreceptores, que, consequentemente, resulta na redução da descarga dos barorreceptores e estimulação do quimiorreceptor. Objetivo: Utilizando a técnica de registro em unidade única, as atividades neuronais do núcleo cuneiforme foram investigadas em estados de hipotensão induzida por hemorragia e administração de um anti-hipertensivo (hidralazina). Métodos: Trinta ratos machos foram divididos nos grupos controle, hemorragia e hidralazina. A artéria femoral foi canulada, para o registro de respostas cardiovasculares, incluindo pressão arterial sistólica, pressão arterial média e frequência cardíaca. A hidralazina foi administrada na veia da cauda. O registro de unidade única foi realizado a partir do núcleo cuneiforme. Resultados: A pressão arterial sistólica máxima e a pressão arterial média diminuíram significativamente, e a frequência cardíaca aumentou significativamente após a aplicação de hidralazina, bem como a hemorragia seguinte, em comparação com o grupo controle. A hipotensão aumentou significativamente a taxa de disparo da população do núcleo cuneiforme em ambos os grupos de hemorragia e hidralazina, em comparação com o grupo de controle. Conclusões: Os presentes dados indicam que as atividades do núcleo cuneiforme após hipotensão podem desempenhar um papel crucial nos vasos sanguíneos e no tônus vasomotor.

ABSTRACT

Abstract Vasoplegic syndrome (VS) comprises a constellation of concurrent signs and symptoms: hypotension, high cardiac index, low systemic vascular resistance, low filling pressures, the tendency to occur diffuse bleeding, and sustained hypotension. All of these parameters may persist even despite the use of high doses of vasoconstrictor amines. VS arises from vasoplegic endothelial dysfunction with excessive release of nitric oxide by polymorphonuclear leukocytes mediated by the nitric oxide synthase's inducible form and is associated with systemic inflammatory reaction and high morbimortality. The achievements regarding the treatment of VS with methylene blue (MB) are a valuable Brazilian contribution to cardiac surgery. The present text review was designed to deliver the accumulated knowledge in the past ten years of employing MB to treat VS after cardiac surgery. Considering that we have already published two papers describing acquired experiences and concepts after 15 and 20 years, now, as we achieve the 30-year mark, we compose a trilogy.

ABSTRACT

Resumen Introducción: El shock hemorrágico es una de las causas más comunes de muerte en pacientes con trauma debido a que pone en marcha un círculo vicioso de mecanismos que incluyen hipotermia, acidosis y coagulopatía. Para mitigar estos efectos, se han propuesto estrategias de control de daños, incluido el aporte controlado de líquidos con hipotensión permisiva contemplando metas en la presión arterial sistólica para mantener una adecuada perfusión de los tejidos. Objetivo: Conocer información actualizada acerca del manejo de la hipotensión permisiva en pacientes con trauma. Metodología: Se buscó información en las bases de datos Web-of-Science y Scopus de los últimos cinco años. El resultado arrojó un total de 118 artículos de los cuales se tomaron 30, según los criterios de inclusión y exclusión. Resultados: Todos los artículos consideran el uso de la hipotensión permisiva como una buena opción para el manejo de los pacientes con trauma e hipotensión, sin embargo, difieren en qué momento es adecuado utilizarlo y en qué condiciones se debe realizar. Conclusiones: Si bien la hipotensión permisiva se ha convertido en uno de los pilares fundamentales en el manejo prehospitalario del paciente con trauma, se requieren estudios investigativos en humanos para soportar cuándo y cómo debe utilizarse.


Abstract Introduction: Hemorrhagic shock is one of the most common causes of death in trauma patients, because it sets in motion a vicious cycle of mechanisms, including hypothermia, acidosis, and coagulopathy. To mitigate these effects, damage control strategies have been proposed, including the controlled intake of fluids with permissive hypotension, contemplating goals in systolic blood pressure, and thus, maintaining adequate tissue perfusion. Objective: The present research aimed to review the literature in search of updated information about the management of permissive hypotension in patients with trauma. Methodology: Information was searched in the Web-of-Science and Scopus databases in the last five years. The result yielded a total of 118 articles, of which 30 were taken according to the inclusion and exclusion criteria. Results: All the articles consider the use of permissive hypotension as a good option for the management of patients with trauma and hypotension, however, they differ when it is appropriate to use it and under what conditions it should be performed. Conclusions: Although permissive hypotension has become one of the fundamental pillars in the prehospital management of the patient with trauma, research studies in humans are required to support when and how it should be used.

ABSTRACT

RESUMO Objetivo: Analisar a associação entre ultrafiltração e gravidade de pacientes diagnosticados com lesão renal aguda com complicações clínicas decorrentes da hemodiálise. Método: Estudo transversal realizado num hospital universitário do Sul do Brasil. Foram incluídas todas as fichas diárias de sessões de hemodiálise de pacientes com lesão renal aguda submetidos à hemodiálise entre setembro e novembro de 2017. Para obtenção dos dados, elaborou-se um instrumento de coleta. Adotou-se nível de significância inferior a 5%. Resultados: Os 103 pacientes estudados fizeram um total de 519 sessões de hemodiálise. Prevaleceram pacientes do sexo masculino (66,7%) com 60 anos ou mais (51,5%). Cerca de metade dos pacientes apresentou volume médio de ultrafiltração >1501ml (51,5%). A maioria foi considerada grave (72,8%). Dentre as complicações, a mais prevalente foi a hipotensão (69,9%). A realização de um maior volume de ultrafiltração não se associou às complicações estudadas. Pacientes graves apresentaram maior chance para ocorrência de hipotensão (p<0,001 e OR: 33,73). Conclusão: Hipotensão durante a hemodiálise foi uma complicação frequente, ocorrendo em cerca de metade dos pacientes. Como não esteve associada a volumes maiores de ultrafiltração, conclui-se que, possivelmente, a maior gravidade do paciente seja um fator explicativo para o desenvolvimento dessa complicação.

Entre las complicaciones, la más prevalente fue la hipotensión (69,9%). La realización de un mayor volumen de ultrafiltración no se asoció a las complicaciones estudiadas. Pacientes graves presentaron mayor predicción de ocurrencia de hipotensión (P0,001 y OR: 33,73). Conclusión: hipotensión durante la hemodiálisis fue una complicación frecuente, ocurriendo en aproximadamente la mitad de los pacientes. Como no estuvo asociada a volúmenes mayores de ultrafiltración, se concluye que, posiblemente, la mayor gravedad del paciente sea un factor explicativo para el desarrollo de esa complicación.


ABSTRACT Objective: To analyze the association between ultrafiltration and severity of patients diagnosed with acute renal injury with clinical complications resulting from hemodialysis. Method: A cross-sectional study was conducted in a teaching hospital in southern Brazil. We included all daily records of hemodialysis sessions of patients with acute kidney injury who underwent hemodialysis between September and November 2017. For data collection, an instrument was developed. A significance level of less than 5% was adopted. Results: The 103 patients under studywent through a total of 519 hemodialysis sessions. Most were male patients (66.7%) aged 60 years or older (51.5%). About half of the patients had mean ultrafiltration volume >1501ml (51.5%). Most were considered critical (72.8%). Among the complications, hypotension (69.9%) was the most prevalent. The performance of a higher volume of ultrafiltration was not associated with the studied complications. Patients with severity showed a higher chance of hypotension (p<0.001 and OR: 33.73). Conclusion: Hypotension during hemodialysis was a frequent complication, presented by nearly half of the patients. As it was not associated with larger ultrafiltration volumes, it is concluded that, possibly, the greater severity of the patient is an explanatory factor for the onset of this complication.

ABSTRACT

Objetivo: Avaliar a prevalência e o manejo da hiperglicemia de estresse em pacientes internados em uma unidade de terapia intensiva. Métodos: Estudo retrospectivo, realizado de janeiro a junho de 2018. Os dados foram obtidos a partir de 582 prontuá- rios eletrônicos, considerando os valores glicêmicos durante a hospitalização, história prévia ou não de diabetes mellitus, causas do internamento, tempo de permanência na unidade de terapia intensiva, presença de complicações durante o internamento e conduta utilizada em caso de hiperglicemia de estresse. Resulta- dos: Dos 582 pacientes internados na unidade de terapia intensi- va, 579 tiveram sua glicemia indicada nos prontuários analisados; 341 (58,9%) apresentaram hiperglicemia em algum momento da internação, sendo a hiperglicemia de estresse caracterizada em 200 pacientes (35%). A duração média de internamento desses pacientes foi de 8,39±10,9 dias, e a causa mais frequente de inter- namento foi devido a pós-operatório por diversas causas, somando 148 indivíduos (74%). Dentro os pacientes, 72 (36%) apresenta- ram alguma complicação. Além disso, 13 casos (6,5%) evoluíram para óbito. Conclusão: Estudos disponíveis sobre alvos de gli- cose em pacientes críticos das unidades de terapia intensiva apresentam difícil interpretação devido às diferenças subs- tanciais no grupo de populações e aos protocolos de gestão de pacientes utilizados em vários centros. Todavia, a prevalência da hiperglicemia de estresse encontrada nesta amostra é se- melhante à de outras casuísticas estudadas. O índice eleva- do de complicações enfatiza a necessidade de padronização nos critérios para diagnóstico e tratamento da hiperglicemia de estresse objetivando melhor prognóstico desses pacientes independentemente da causa do internamento.


Objective: To evaluate the prevalence and management of stress hyperglycemia in patients hospitalized in anintensive care unit. Methods: Retrospective study, carried out from January to June 2018. Data were obtained from 582 electronic medical records, considering glycemic values during hospitalization, existence of previous history of Diabetes Mellitus, causes of hospitalization, length of stay in the intensive care unit, presence of complications during hospitalization, and behavior used in case of stress hyper- glycemia. Results: Of the 582 patients admitted in the ICU, 579 had their glycemia indicated in the charts analyzed: 341 (58,9%) had hyperglycemia in a certain moment of hospitalization, with stress hyperglycemia being present in 200 patients (35%). The average duration of hospitalization of these patients was 8,39 ± 10,9 days, and the most frequent cause of hospitalization was postoperative for various causes, totaling 148 individuals (74%). Of the patients, 72 (36%) presented some type of complication and 13 patients (6,5%) died. Conclusion: Available studies on glucose targets in critical intensive care unit patients are difficult to be interpre- ted because of substantial differences in the study populations and of patient management protocols used at various centers. However, the prevalence of stress hyperglycemia found in this sample is similar to that of other study groups. The high com- plication rate emphasizes the need for standardization of the criteria for diagnosis and treatment of stress hyperglycemia aiming at a better prognosis of these patients regardless of the cause of hospitalization.

ABSTRACT

With the advancement of disease treatments, the number of patients undergoing surgery worldwide is increasing. However, many patients still experience severe perioperative complications. Perioperative hypotension is one of the common side effects during surgery. Physiologically, perioperative hypotension can lead to insufficient perfusion of important organs and result in acute and chronic irreversible organ injury, which cause serious consequences for the patient's postoperative hospitalization and even the long-term outcome. Therefore, in order to optimize perioperative circulation management and improve the quality of life for patients after surgery, it is of great importance to investigate the relationship between perioperative hypotension and postoperative myocardial injury, ischemic stroke, postoperative delirium, acute kidney injury, and postoperative mortality. Individualized circulation management and reasonable application of vasoactive drugs may be the key point to early prevention and correct treatment of perioperative hypotension, which is of great significance for reducing perioperative related morbidity and mortality and improving the prognosis for the surgical patients.

ABSTRACT

BACKGROUND@#Hypotension is a common complication caused by spinal anesthesia (SA), which may have adverse impacts on the condition of the parturient and fetus. Liquid infusion was found to be relatively effective for reducing the incidence of hypotension. However, the question of whether colloid preload can optimize hemodynamic variables in the cesarean section remains controversial. This study aims to determine the effects of colloid preload on the incidence of hypotension induced by SA in elective cesarean section.@*METHODS@#Related keywords were searched on PubMed, EMBASE, and Cochrane Library from inception dates to May 2020. Studies included were evaluated for eligibility and quality. The primary outcome was the intra-operative incidence of hypotension and severe hypotension. The secondary outcomes included the lowest intra-operative systolic blood pressure, the maximal intra-operative heart rate, the intra-operative needs of ephedrine and phenylephrine, the incidence of maternal nausea and/or vomiting, and neonatal outcomes (umbilical artery pH and Apgar scores). Apart from the above, RevMan 5.3 was used for the data analysis.@*RESULTS@#Altogether nine randomized controlled trials were included in the meta-analysis. There were no significant differences in the incidence of intra-operative hypotension, severe hypotension, or neonatal outcomes between the colloid preload group and control group, except for the umbilical artery pH.@*CONCLUSION@#This meta-analysis suggests that colloid preload does not significantly reduce the incidence of hypotension associated with SA in elective cesarean section.

ABSTRACT

BACKGROUND@#Norepinephrine infusion decreases hypotension after spinal anesthesia during cesarean section. This study aimed to compare the efficacy of norepinephrine infusion and ephedrine bolus against post-spinal hypotension in parturients.@*METHODS@#In this double-blinded, randomized controlled clinical trial, parturients scheduled for elective cesarean section were randomly allocated to receive norepinephrine infusion (0.05 μg·kg-1·min-1) just before spinal anesthesia continuing for 30 min or ephedrine bolus (0.15 mg/kg) just before spinal anesthesia. A rescue bolus (5 μg norepinephrine for the norepinephrine group, and 5 mg ephedrine for the ephedrine group) was administered whenever hypotension occurred. Our primary outcome was the incidence of hypotension within 30 min of spinal anesthesia administration. Secondary outcomes included maternal and neonatal outcomes 30 min after spinal block, and neonatal cerebral oxygenation 10 min after birth.@*RESULTS@#In total, 190 patients were enrolled; of these patients, 177 were included in the final analysis. Fewer patients suffered hypotension in the norepinephrine group than in the ephedrine group (29.5% vs. 44.9%, odds ratio [OR]: 0.51, 95% confidence interval [CI]: 0.28-0.95, P = 0.034). Moreover, the tachycardia frequency was lower in the norepinephrine group than in the ephedrine group (OR: 0.22, 95% CI: 0.11-0.44, P < 0.001), and patients suffered less nausea and vomiting (OR: 0.28, 95% CI: 0.11-0.70, P = 0.004). There was no difference in Apgar scores and umbilical arterial blood gas analysis between the two groups. However, neonatal cerebral regional saturations were significantly higher after birth in the norepinephrine group than in the ephedrine group (mean difference: 2.0%, 95% CI: 0.55%-3.45%, P = 0.008).@*CONCLUSION@#In patients undergoing elective cesarean section with spinal anesthesia, norepinephrine infusion compared to ephedrine bolus resulted in less hypotension and tachycardia, and exhibited potential neonatal benefits.@*TRIAL REGISTRATION@#ClinicalTrials.gov, NCT02542748; https://clinicaltrials.gov/ct2/show/record/NCT02542748.
