ABSTRACT

Objective To analyze the influence of intraoperative blood glucose fluctuation and postoperative insulin resistance(IR)on postoperative cognitive dyfunction(POCD)in elderly patients undergoing thoracoscopic radical resection of lung cancer under general anesthesia.Methods A total of 352 elderly patients undergoing thoracoscopic radical resection of lung cancer under general anesthesia were collected and divided into the POCD group(n=84)and the non-POCD group(n=268).The covariates between the two groups were balanced by propensity score matching method(PSM).Eighty-four cases in each group were successfully matched.The data between the two groups before and after PSM were compared.After PSM,receiver operating characteristic(ROC)curve of blood glucose fluctuation amplitude for predicting POCD was drawn,and patients were divided into the low-level blood glucose fluctuation group(n=97)and the high-level blood glucose fluctuation group(n=71)according to the cut-off value.According to the existence of postoperative IR,patients were divided into the IR group(n=53)and the non-IR group(n=115).Then,incidences of POCD between groups were compared.Logistic regression was used to analyze the influencing factors of POCD.Results Before PSM,the POCD group had older age,higher blood glucose fluctuation amplitude,IR ratio,operation time,anesthesia time,propofol dosage,remifentanil dosage and sufentanil dosage in anesthesia maintenance period than those in the non-POCD group(P<0.05).The POCD group had higher blood glucose fluctuation amplitude and IR ratio than those in the non-POCD group after PSM(P<0.05).After PSM,the incidences of POCD in the high-level blood glucose fluctuation group and the IR group were higher than those in the low-level blood glucose fluctuation group and the non-IR group(P<0.05).Logistic regression analysis showed that higher intraoperative blood glucose fluctuation(OR=9.140,95%CI:4.338-19.257)and postoperative IR(OR=4.034,95%CI:1.163-13.991)were risk factors of POCD.Conclusion The risk of POCD in elderly patients undergoing thoracoscopic radical lung cancer surgery under general anesthesia is increased in patients with higher intraoperative blood glucose fluctuation and postoperative IR.

ABSTRACT

Objective:To compare the effects of transverse abdominis plane block and incision infiltration anesthesia on the early postoperative recovery in the patients undergoing thoracoscopic lung resection with general anesthesia.Methods:Eighty American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ patients, regardless of gender, aged 50-78 yr, with body mass index of 18-30 kg/m 2, scheduled for elective thoracoscopic lung resection under general anesthesia, were divided into 2 groups ( n=40 each) using a random number table method: incision local infiltration group (group D) and transverse abdominis plane block group (group E). In group E, the patients were changed to the lateral position after completion of anesthesia induction, ultrasound-guided transverse abdominis plane block was performed on the affected side, with 0.25% ropivacaine hydrochloride 30 ml injected. In group D, infiltration anesthesia with 0.25% ropivacaine hydrochloride was performed before incision. Postoperative patient-controlled intravenous analgesia was carried out, and flurbiprofen axetil was intravenously injected for rescue analgesia when the numerical rating scale score at rest >3 or numerical rating scale score≥6 while coughing. Quality of Recovery-15 scale scores were assessed at 1 day before surgery and 24 and 48 h after surgery. Plasma concentrations of interleukin-6 (IL-6) and IL-1β were measured by enzyme-linked immunosorbent assay before incision, at the end of surgery, and at 24 h after surgery. The amount of remifentanil used during surgery, the number of effective pressing times of patient-controlled analgesia within 48 h after surgery, requirement for rescue analgesia, first ambulation time after surgery, time to first flatus, length of hospital stay, and occurrence of nausea and vomiting and pulmonary infection within 48 h after surgery were recorded. Results:Compared with group D, Quality of Recovery-15 scale scores were significantly increased, the amount of remifentanil used during surgery and the number of effective pressing times of patient-controlled analgesia were reduced, the rate of rescue analgesia was decreased, the time to first rescue analgesia was prolonged, and the time to first flatus was shortened in group E ( P<0.05). There were no significant differences in the plasma concentrations of IL-6 and IL-1β at various time points, time to first ambulation after surgery, length of hospital stay, and incidence of nausea and vomiting and pulmonary infection between the two groups ( P>0.05). Conclusions:Compared with incision infiltration anesthesia, transverse abdominis plane block can reduce intraoperative consumption of opioids, alleviate postoperative pain, and promote early postoperative recovery when used for thoracoscopic lung resection under general anesthesia.

ABSTRACT

Objective:To investigate the effect of combined use of midazolam and remifentanil without muscle relaxant on tracheal intubation in female patients undergoing breast surgery.Methods:A retrospective analysis was performed on 40 female patients with breast disease who underwent tracheal intubation and general anesthesia at The First Affiliated Hospital of Zhengzhou University between January 2023 and June 2023. These patients were divided into a control group ( n = 20) and an observation group ( n = 20) based on whether muscle relaxants were applied at the time of intubation. The control group received intravenous rocuronium bromide, whereas the observation group did not use muscle relaxants. Both groups were intravenously administered midazolam (0.1 mg/kg) and remifentanil (4 μg/kg) prior to tracheal intubation. The intubation conditions were evaluated based on factors such as the ease of inserting the laryngoscope and the patient's response to intubation, including coughing. Results:There were no statistically significant differences in age, height, and body mass between the two groups (all P > 0.05). The excellent rate of intubation conditions was significantly lower in the observation group compared with the control group [45% (9/20) vs. 85% (17/20), χ2 = 7.03, P = 0.008). The good rate of intubation conditions was significantly higher in the observation group compared with the control group [40% (8/20) vs. 5% (1/20), χ2 = 7.03, P < 0.05]. There was no statistically significant difference in the excellent and good rates of intubation conditions between the observation and control groups [85% (17/20) vs. 90% (18/20), χ2 = 0.23, P > 0.05]. No significant difference in intraoperative awareness score was observed between the observation and control groups [(2.59 ± 0.44) points vs. (2.61 ± 0.31) points, P > 0.05]. None of the patients in either group exhibited any episodes of arrhythmias. Furthermore, no adverse reactions such as muscle stiffness, nausea, vomiting, or skin itching were observed in either group following the surgical procedure. Conclusion:Without the use of muscle relaxants, intravenous administration of midazolam at 0.1 mg/kg and remifentanil at 4 μg/kg for tracheal intubation in female patients undergoing breast surgery can offer excellent intubation conditions, ensuring that the patient remains unconscious throughout the surgical procedure.

ABSTRACT

Abstract Background After recently published randomized clinical trials, the choice of the best anesthetic procedure for mechanical thrombectomy (MT) in acute ischemic stroke (AIS) due to large vessel occlusion (LVO) is not definite. Objective To compare the efficacy and safety of general anesthesia (GA) versus conscious sedation (CS) in patients with AIS who underwent MT, explicitly focusing on procedural and clinical outcomes and the incidence of adverse events. Methods PubMed, Embase, and Cochrane were systematically searched for randomized controlled trials (RCTs) comparing GA versus CS in patients who underwent MT due to LVO-AIS. Odds ratios (ORs) were calculated for binary outcomes, with 95% confidence intervals (CIs). Random effects models were used for all outcomes. Heterogeneity was assessed with I2 statistics. Results Eight RCTs (1,300 patients) were included, of whom 650 (50%) underwent GA. Recanalization success was significantly higher in the GA group (OR 1.68; 95% CI 1.26-2.24; p < 0.04) than in CS. No significant difference between groups were found for good functional recovery (OR 1.13; IC 95% 0.76-1.67; p = 0.56), incidence of pneumonia (OR 1.23; IC 95% 0.56- 2,69; p = 0.61), three-month mortality (OR 0.99; IC 95% 0.73-1.34; p = 0.95), or cerebral hemorrhage (OR 0.97; IC 95% 0.68-1.38; p = 0.88). Conclusion Despite the increase in recanalization success rates in the GA group, GA and CS show similar rates of good functional recovery, three-month mortality, incidence of pneumonia, and cerebral hemorrhage in patients undergoing MT.


Resumo Antecedentes A trombectomia mecânica (TM) é o padrão de tratamento para pacientes com acidente vascular cerebral isquêmico agudo (AVCI) devido à oclusão de grandes vasos (OGV). No entanto, ainda não está claro qual é o procedimento anestésico mais benéfico para a TM. Objetivo Nosso objetivo foi comparar a eficácia e a segurança da anestesia geral (AG) versus sedação consciente (SC) em pacientes com AVCI submetidos à TM, focando especificamente nos resultados procedimentais e clínicos, bem como na incidência de eventos adversos. Métodos Foram realizadas buscas sistemáticas nas bases PubMed, Embase e Cochrane por ensaios clínicos randomizados (ECRs) comparando AG versus SC em pacientes submetidos à TM devido a AVCI por OGV. Razões de chances (ORs) foram calculadas para desfechos binários, com intervalos de confiança de 95% (ICs). Modelos de efeitos aleatórios foram usados para todos os resultados. A heterogeneidade foi avaliada com estatísticas I2. Resultados Oito ensaios clínicos randomizados (1.300 pacientes) foram incluídos, dos quais 650 (50%) foram submetidos à AG. O sucesso da recanalização foi significativamente maior no grupo AG (OR 1,68; IC 95% 1,26-2,24; p < 0,04) em comparação com SC. No entanto, não houve diferença significativa entre os grupos para recuperação funcional adequada (OR 1,13; IC 95% 0,76-1,67; p = 0,56), incidência de pneumonia (OR 1,23; IC 95% 0,56- 2,69; p = 0,61), mortalidade em três meses (OR 0,99; IC 95% 0,73- 1,34; p = 0,95) ou hemorragia cerebral (OR 0,97; IC 95% 0,68- 1,38; p = 0,88). Conclusão Apesar do aumento significativo nas taxas de sucesso de recanalização no grupo AG, AG e SC mostram taxas semelhantes de recuperação funcional, mortalidade, pneumonia e hemorragia em pacientes com AVCI submetidos à TM.

ABSTRACT

Introduction: Postoperative nausea and vomiting (PONV) are common complications in surgical patients undergoing general anesthesia, and multiple strategies have been suggested to prevent them. Objective: To describe the available evidence on the effectiveness of pharmacological and non-pharmacological strategies for preventing PONV in adults undergoing surgery under general anesthesia, as reported in previous meta-analyses and systematic reviews. Methodology: An overview of systematic reviews and meta-analyses was conducted. Searches were performed in PubMed, EBSCO, EMBASE, Cochrane Database, Science Direct, and Scopus, without restrictions as to gender, clinical condition, or date of publication, including articles in Spanish, French, and English only. Two reviewers independently and in duplicate did the screening, data extraction, quality evaluation, and risk of bias assessment according to AMSTAR-2. The PRISMA and PRIOR statements were followed for reporting. PROSPERO registration number CRD42021251999. Results: Out of 80 candidate articles, three were viable for meta-analysis. 1.5 mg to 18 mg doses of Dexamethasone showed a significant reduction in the risk of PONV, with a RR of 0.48 (95 % CI 0.41-0.57; p<0.001), I2=63 % (p=0.07), and a NNTc of 5 and 7. Other effective strategies included the use of acoustic stimulation/acupuncture/acupressure, 5HT3 antagonists, NK1 antagonists, gabapentinoids, haloperidol, droperidol, metoclopramide, midazolam, mirtazapine, among others. The risk of publication bias was low. Conclusion: Different strategies are effective for PONV prophylaxis in surgeries under general anesthesia. Dexamethasone shows the best available evidence at the moment. The documented methodological quality suggests the need for better studies to establish the effectiveness of the strategies.

ABSTRACT

Objective:To investigate the effects of combined spinal-epidural anesthesia (CSEA) on postoperative pain and short-term cognitive function in elderly patients undergoing hip fracture surgery.Methods:A total of 60 elderly patients undergoing hip fracture surgery in Dongchangfu District of Liaocheng People′s Hospital from October 2018 to September 2020 were selected as subjects and they were divided into the control group and the observation group by performed different anaesthesias methods, with 30 patients in each group. The control group underwent total intravenous anesthesia (TIVA), and the observation group underwent CSEA. The scores of visual analogue scale (VAS) at different points and the analgesic recovery rate within 48 h of the two groups were compared, and mini mental state evaluation (MMSE) scores of two groups at different points were evaluated. The levels of serum interleukin (IL)-6, IL-10 and tumor necrosis factor-α (TNF-α) of the two groups before the surgery and on the 1 d after the surgery were compared, and adverse events after the surgery were observed.Results:The analgesic recovery rate within 48 h in the observation group was lower than that in the control group: 3.33%(1/30) vs. 26.67%(8/30), the difference was statistically significant ( χ2 = 6.40, P<0.05). The VAS scores at 4, 6, 12, 24, 48 h after the surgery in the observation group were lower than those in the control group ( P<0.05). The scores of MMSE at 1 and 3 d after the surgery in the observation group were higher than those in the control group: (25.38 ± 2.86) scores vs. (22.17 ± 2.72) scores, (26.89 ± 3.04) scores vs. (25.17 ± 2.69) scores, the differences were statistically significant ( P<0.05). At 1 d after the surgery, the levels of IL-6, TNF-α in the observation group were lower than those in the control group: (67.59 ± 15.47) ng/L vs. (86.75 ± 17.88) ng/L, (18.75 ± 4.23) ng/L vs. (22.81 ± 4.30) ng/L; and the level of IL-10 was higher than that in the control group: (39.78 ± 8.31) ng/L vs. (34.76 ± 7.54) ng/L, the differences were statistically significant ( P<0.05). There was no statistical difference in the total incidence of postoperative adverse events between the two groups ( P>0.05). Conclusions:CSEA can effectively relieve postoperative pain, improve short-term cognitive function, reduce inflammatory response in elderly patients with hip fracture surgery, and with great safety.

ABSTRACT

Objective:To investigate the effect of acupoint stimulation assisted anesthesia on the agitation during recovery and the levels of serum opioids (Opiorphin) and amyloid A (SAA) in elderly patients after hip fracture surgery.Methods:Eighty-six older patients who underwent hip fracture surgery in Shaoxing Second Hospital from February 2020 to September 2021 were randomly divided into the routine group and the research group, each with 43 patients. They were given acupoint sham stimulation and acupoint stimulation respectively, and the general indexes of the two groups, recovery quality, cognitive function and changes in serum Opiorphin and SAA levels were compared.Results:There were no differences in operation time, anesthesia time, recovery time and intraoperative blood transfusion between the two groups ( P>0.05). The dosage of remifentanil in the research group was significantly lower than that in the routine group: (270.64 ± 17.62) μg vs. (291.82 ± 23.34) μg, P<0.05. The incidence of agitation during the recovery period in the research group was significantly lower than that in the routine group: 13.95% (6/43) vs. 48.84% (21/43), P<0.05. The mini-mental state examination (MMSE) scores in the research group at 12, 24 and 48 h after operation were significantly higher than those in the routine group: (22.80 ± 2.04) scores vs. (19.31 ± 3.61) scores, (24.92 ± 2.44) scores vs. (21.49 ± 3.58) scores, (26.73 ± 2.57) scores vs. (24.23 ± 3.95) scores, there were statistical differences ( P<0.05). The serum Opiorphin level at 24 h after operation in the research group was higher than that in the routine group: (32.74 ± 8.57) mg/L vs. (25.40 ± 6.36) mg/L; and the SAA level was lower than that in the routine group: (157.36 ± 10.24) mg/L vs. (204.37 ± 15.56) mg/L, there were statistical differences ( P<0.05). Conclusions:Acupoint stimulation adjuvant anesthesia can reduce the occurrence of agitation during the recovery period of elderly patients with hip fracture, reduce the dosage of anesthetics, reduce postoperative cognitive impairment, regulate serum Opiorphin and SAA levels, and help early postoperative recovery.

ABSTRACT

Objective:To investigate the effects of dexmedetomidine on vital signs during recovery from general anesthesia in gynecological patients undergoing general anesthesia surgery and analysis of risk factors for complications.Methods:A total of 80 gynecological patients undergoing general anesthesia surgery who received treatment in Lishui People's Hospital from March 2021 to March 2022 were included in this study. They were randomly divided into an observation group and a control group ( n = 40/group). All patients were subjected to general anesthesia. The observation group was infused with 0.5 μg/kg dexmedetomidine intravenously 15 minutes before induction of anesthesia and then infused with dexmedetomidine at a rate of 0.2 μg/kg per hour until 20-30 minutes before the end of the operation. The control group was identically given 0.9% normal saline. The recovery quality, vital signs before surgery and during recovery from general anesthesia (systolic blood pressure, diastolic blood pressure, heart rate, body temperature), and complications during recovery from general anesthesia were compared between the two groups. These patients were divided into a complication group and a non-complication group according to whether there were complications during recovery from general anesthesia. Univariate and multivariate Logistic regression analyses were performed to analyze the high-risk factors for complications occurring during recovery from general anesthesia in gynecological patients undergoing general anesthesia surgery. Results:The time to awaken, time to recover spontaneous respiration, and time to extubation in the observation group were significantly shorter than those in the control group ( t = 3.74, 2.97, 2.56, all P < 0.05). Systolic blood pressure, diastolic blood pressure, and heart rate measured during recovery from general anesthesia were significantly lower in the observation group compared with the control group ( t = 5.71, 4.53, 4.53, all P < 0.001). Body temperature ( t = 4.40, P < 0.001) and the incidence of complications ( χ2 = 5.69, P < 0.05) were significantly lower in the observation group compared with the control group. These patients were divided into complication ( n = 22) and non-complication ( n = 58) groups according to whether they had complications during recovery from general anesthesia. Univariate and multivariate logistic regression analyses showed that American Association of Anesthesiologists grade II, presence of underlying diseases, abnormal leukocyte count, and no use of dexmedetomidine were the risk factors for postoperative complications in gynecological patients undergoing general anesthesia surgery ( OR = 2.38, 2.86, 2.17, 3.60, all P < 0.05). Conclusion:Dexmedetomidine can improve awakening quality and vital signs and reduce complications during recovery from general anesthesia. American Association of Anesthesiologists grade, underlying disease, abnormal white blood cell count, and no use of dexmedetomidine are the risk factors for complications occurring during recovery from general anesthesia in gynecological patients undergoing general anesthesia surgery.

ABSTRACT

Objective:To investigate the effects of remimazolam besylate and midazolam on postoperative cognitive function of patients undergoing gynecologic laparoscopic surgery under general anesthesia.Methods:From May 2019 to January 2021, 120 patients with gynecological laparoscopic surgery under general anesthesia in Haikou Maternal and Child Health Hospital were selected and divided into control group (60 cases) and observation group (60 cases) by random number table. The control group was given 0.05 mg/kg midazolam and 0.50 μg/kg sufentanil and 0.15 mg/kg vecuronium bromide were used for anesthesia induction. Patients in the observation group were given 0.3 mg/kg remimazolam besylate and 0.50 μg /kg sufentanil and 0.15 mg/kg vecuronium were used for anesthesia induction. The levels of hemodynamic indexes before anesthesia (T 0), during anesthesia (T 1), and after intubation (T 2) as well as the levels of postoperative anesthesia recovery indexes were compared between the two groups. The Visual Analogue Scale (VAS) score and Mini-Mental State Examination (MMSE) scores were recorded and compared before surgery, 24 h, 72 h after surgery. The total incidence of adverse reactions after surgery was recorded and compared between the two groups. Results:The heart rate (HR) at T 1 and T 2 in the two groups was higher than that at T 0, the oxygen saturation (SpO 2) at T 1 and T 2 was lower than that at T 0, the mean arterial pressure (MAP) at T 1 was lower than that at T 0, and the MAP at T 2 was higher than that at T 0, with statistically significant difference (all P<0.05); The HR and MAP at T 1 and T 2 in the observation group were lower than those in the control group, and SpO 2 was higher than those in the control group (all P<0.05); The recovery time of spontaneous respiration, eye opening time and extubation time in the observation group were significantly shorter than those in the control group (all P<0.05); The MMSE score at 24 h and 72 h after operation was lower than that before operation, and the VAS score at 24 h was higher than that before operation in both groups (all P<0.05); The MMSE scores in the observation group at 24 h and 72 h after operation were significantly higher than those in the control group (all P<0.05), and there was no significant difference in the VAS scores at 24 h and 72 h after operation between the two groups ( P>0.05); There was no significant difference in the total incidence of adverse reactions between the two groups (all P>0.05). Conclusions:Remimazolam besylate has little effect on cognitive function of patients undergoing gynecologic laparoscopic surgery under general anesthesia, with fast recovery and high safety, which is worthy of clinical promotion.

ABSTRACT

Objective:To observe the effect of general anesthesia combined with serratus anterior plane block (SAPB) on the quality of life and postoperative pain of patients undergoing breast cancer surgery.Methods:The clinical data of 80 patients with breast cancer undergoing elective modified radical mastectomy admitted to the Affiliated Hospital of Guilin Medical College from January 2020 to March 2021 were retrospectively analyzed. According to different anesthesia methods, they were divided into control group and observation group, with 40 cases in each group. The control group received simple general anesthesia, while the observation group received general anesthesia combined with SAPB. The degree of postoperative pain in the two groups at 3, 6, 12 and 24 h after surgery was evaluated with the Numerical Rating Scale (NRS) score, and the postoperative recovery at 24 h after surgery and quality of life at 3 h and 6 months after surgery were evaluated with the Quality of Recovery-40 (QoR-40) score and the Short Form of Health Survey (SF-36). The serum levels of pain related cytokines[neuropeptide Y (NPY), prostaglandin E2 (PGE2), and 5-hydroxytryptamine (5-HT) ] in the two groups were compared. The complications of the two groups were recorded.Results:The NRS score in the observation group at 6 h and 12 h after operation were lower than those in the control group (all P<0.05). The QoR-40 score at 24 h after operation and SF-36 score at 6 months after operation in the observation group were higher than those in the control group (all P<0.05). There was no significant difference in the incidence of postoperative complications between the two groups ( P>0.05). The NPY, PGE2 and 5-HT levels of patients in the observation group were lower than those in the control group at 24 h after operation (all P<0.05). Conclusions:The use of general anesthesia combined with SAPB in modified radical mastectomy for breast cancer can alleviate postoperative pain and improve long-term quality of life, which may be related to the reduction of pain related cytokine secretion.

ABSTRACT

Objective:To investigate the effect of right stellate ganglion block (RSGB)-serratus anterior plane block (SAPB) combined with general anesthesia in thoracoscopic radical resection of lung cancer.Methods:A total of 90 patients who planned to undergo thoracoscopic radical resection of lung cancer in Xiangya Changde Hospital from March 2020 to September 2021 were prospectively selected and divided into 3 groups by random number table method: general anesthesia group (G group), (SAPB)+ general anesthesia group (SG group), RSGB+ SAPB+ general anesthesia group (RSG group), 30 cases in each group. The SG group received SAPB on the operative side before general anesthesia, and the RSG group received RSGB+ SAPB on the operative side before general anesthesia. After the blocking effect was determined, all patients were given general anesthesia in the same scheme according to their weight, and patients were given patient-controlled intravenous analgesia (PCIA) after surgery. The mean arterial pressure (MAP) and heart rate (HR) were recorded before anesthesia (T 0), before intubation (T 1), 1 min after intubation (T 2), 5 min after intubation (T 3), at extubation (T 4) and 5 min after extubation (T 5). The intraoperative dosage of remifentanil, incidence of nausea and vomiting (PONV) within 24 hours after surgery, number of additional PCIA within 24 hours, the Visual Analogue Scale (VAS) of static and dynamic pain, the Bruggrmann Comfort Scale (BCS) and Richard Campbell Sleep Questionnaire (RSCQ) 24 hours after surgery were recorded. Results:Compared with T 0, the MAP and HR in 3 groups were increased 1 min after intubation (T 2) and at extubation (T 4), but the increases in RSG group were significantly less than those in G and SG groups (all P<0.05). The remifentanil dosage, PONV incidence and PCIA supplemental times in SG and RSG groups were less than those in G group, and the BCS score and RSCQ score were higher than those in G group (all P<0.05); the BCS score and RSCQ score in RSG group were higher than those in SG group (all P<0.05). Conclusions:RSGB+ SAPB combined with general anesthesia in thoracoscopic radical resection of lung cancer has little circulation fluctuation, good postoperative analgesia effect, less adverse reactions and high comfort level.

ABSTRACT

Objective:To investigate the effect of ultrasound monitoring of inferior vena cava collapse index (IVC-CI) guiding fluid replacement on circulation in elderly patients during induction of general anesthesia.Methods:A total of 71 elderly patients who underwent elective surgery under general anesthesia and tracheal intubation at Hunan Provincial People′s Hospital from April 2021 to September 2022 were randomly divided into control group (35 cases) and observation group (36 cases) using a random number table method. Before anesthesia, both groups of patients underwent IVC ultrasound examination and calculated the IVC-CI value. For patients with IVC-CI≥40%, the observation group was given 8 ml/kg of crystal solution before anesthesia induction, while the control group was not treated. The incidence of hypotension, the use of vasoactive drugs, and the total infusion volume from anesthesia induction to skin incision were recorded in two groups. Mean arterial blood pressure (MBP), heart rate (HR), oxygen saturation (SpO 2), cardiac index (CI), and cardiac volume variability (SVV) before anesthesia (T 0), 5 min after induction (T 1), 1 min after tracheal intubation (T 2), 5 min after tracheal intubation (T 3), 10 min after tracheal intubation (T 4), and 1 min before skin incision (T 5) were recorded and compared between the two groups. Results:The incidence of hypotension (27.8% vs 60.0%) and utilization rate of vasoactive drugs (25.0% vs 48.6%) in the observation group were lower than those in the control group, and the total infusion volume during anesthesia induction was higher than that in the control group, with statistical significance (all P<0.05). SVV, CI and MBP at T 1, T 3, T 4 and T 5 were significantly different from those at T 0 in the control group ( F=3.85, 14.66, 3.96, all P<0.05). SVV, CI and MBP at T 1, T 3, T 4 and T 5 in the observation group were significantly different from those at T 0 ( F=3.51, 13.20, 4.35, all P<0.05). There was no significant difference in SVV, CI, MBP, HR and SpO 2 between 2 groups (all P>0.05). Conclusions:For the elderly patients with preoperative IVC-CI≥40%, pre-filling with 8ml/kg crystal solution before anesthesia induction can significantly reduce the incidence of hypotension and the utilization rate of vasoactive drugs in the elderly patients during anesthesia induction.

ABSTRACT

Objective:To evaluate the effect of transcutaneous electrical acupoint stimulation (TEAS) on postoperative patient-controlled intravenous analgesia in pediatric patients undergoing lower extremity orthopedic surgery.Methods:Sixty-eight pediatric patients of both sexes, aged 3-15 yr, of American Society of Anesthesiologists physical status Ⅰor Ⅱ, undergoing elective lower extremity orthopedic surgery under general anesthesia, were divided into 2 groups ( n=34 each) by the random number table method: TEAS group (group T) and control group (group C). In group T, the bilateral Hegu and Neiguan acupoints were stimulated starting from 10 min before induction of anesthesia until the end of procedure, with the frequency of disperse-dense wave of 2/10 Hz, and the current intensity was gradually adjusted to the maximum intensity (10-15 mA) that children could tolerate. In group C, the electrodes were applied to the same acupoints, but electrical stimulation was not applied. The severity of pain was assessed by the Faces Pain Scale-Revised scale immediately after returning to the ward and at 2, 24 and 48 h after operation. The emergence agitation was evaluated using the Pediatric Anesthesia Emergence Delirium scale. The intraoperative consumption of propofol and remifentanil and time to extubation after stopping administration were recorded. The time to first pressing of patient-controlled analgesia (PCA), effective pressing times of PCA on 1st and 2nd days after surgery and postoperative adverse reactions such as postoperative nausea and vomiting, pruritus, drowsiness, and respiratory depression were recorded. Results:Compared with group C, the Faces Pain Scale-Revised scale scores were significantly decreased immediately after returning to the ward and at 2, 24 and 48 h after operation, the incidence of emergence agitation and intraoperative consumption of remifentanil were decreased, the time to extubation was shortened, the time to first pressing of PCA was prolonged, and the effective pressing times of PCA on 1st and 2nd days after surgery were decreased ( P<0.05). There was no significant difference in the intraoperative consumption of propofol and incidence of postoperative adverse reactions between the two groups ( P>0.05). Conclusions:TEAS can effectively enhance the effect of postoperative patient-controlled intravenous analgesia in pediatric patients undergoing lower extremity orthopedic surgery.

ABSTRACT

Objective:To identify the risk factors for postoperative cognitive dysfunction (POCD) and develop the prediction model in elderly patients undergoing lumbar surgery under general anesthesia.Methods:The elderly patients undergoing elective lumbar surgery under general anesthesia in our hospital from July 2021 to July 2022 were enrolled. Cognitive function was assessed at 7 days after surgery using Mini-Mental State Examination and Montreal Cognitive Assessment. When the decrease in both scales≥ 1 standard deviation, the patients were considered as having POCD. The patients were divided into POCD group and non-POCD group according to whether POCD developed. The propensity score matching was used to balance the confounding bias between two groups. The multivariate logistic regression analysis was used to identify the risk factors for POCD. The prediction model was constructed, and a nomogram was drawn for visualization of the model. The receiver operating characteristic curve, calibration plot and decision curve analysis (DCA) were drawn to evaluate the differentiation, consistency and clinical validity of the model, respectively.Results:A total of 159 patients were enrolled in this study, and the incidence of POCD was 31.4%. There were statistically significant differences in the ratio of intraoperative blood transfusion, cumulative time of hypotension, total infusion volume and operation time between two groups ( n=32 each) after propensity score matching ( P<0.05). The results of multivariate logistic regression showed that age, educational levels, diabetes mellitus, previous two or more operations under general anesthesia, APTT and cumulative time of hypotension were independent risk factors for POCD in elderly patients undergoing lumbar surgery under general anesthesia ( P<0.05). A model was developed based on the risk factors mentioned above: LogitP=-15.878+ 0.263 × Age (years) - 0.122 × Educational Level (years)+ 1.601 × Diabetes Mellitus+ 1.468 × History of General Anesthesia for 2 or more times+ 0.608 × Cumulative Time of Hypotension(min) - 0.140 × APTT (s). The area under the receiver operating characteristic curve was 0.930 (95% CI 0.887-0.973), the sensitivity was 0.920, specificity was 0.798 and Youden index was 0.718. After visualizing the model via nomogram, the model was verified by Hosmer-Lemeshow test, P=0.403, C index was 0.930, and corrected C index was 0.914. Conclusions:Age, educational levels, diabetes mellitus, previous multiple operations under general anesthesia, APTT and cumulative time of hypotension are independent risk factors for POCD in elderly patients undergoing lumbar surgery under general anesthesia, and the established risk prediction model can effectively predict the occurrence of POCD in elderly patients undergoing lumbar surgery under general anesthesia.

ABSTRACT

Objective:To evaluate the effect of continuous positive airway pressure(CPAP) ventilation strategy during induction of general anesthesia on atelectasis after induction in obese patients.Methods:A total of 86 patients, aged 30-60 yr, with body mass index of 28-35 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅱor Ⅲ, scheduled for elective cerebrovascular intervention under general anesthesia, were divided into 2 groups ( n=43 each) using a random number table method: CPAP group (group C) and routine group (group R). Group C received CPAP 5 cmH 2O-assisted ventilation after preoxygenation for spontaneous breathing and disappearance of spontaneous breathing. Chest CT scan and arterial blood gas analysis were performed after entering the operating room (T 1) and 5 min after endotracheal intubation (T 2) to calculate the percentage of atelectasis area and to record PaO 2. Dynamic lung compliance and plateau pressure were recorded at T 2. Mean minute ventilation under controlled breathing, P ETCO 2, and use of vasoactive drugs during induction were recorded. The occurrence of reflux and aspiration during mask ventilation was recorded. The development of pulmonary complications within 3 days after operation was recorded. Results:Compared with group R, the percentage of atelectasis area at T 2 was significantly decreased, PaO 2, dynamic lung compliance and plateau pressure were increased ( P<0.05), and no significant change was found in mean minute ventilation, P ETCO 2, requirement for vasoactive drugs and incidence of pulmonary complications in group C ( P>0.05). No reflux or aspiration was observed during mask ventilation. Conclusions:CPAP (5 cmH 2O) strategy during anesthesia induction can reduce the degree of atelectasis after induction in obese patients.

ABSTRACT

Objective:To evaluate the efficacy of pecto-intercostal fascial block (PIFB)-pectoral nerve block type Ⅱ (PECS Ⅱ block)-general anesthesia for modified radical mastectomy.Methods:Forty-six patients, of American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ, aged 40-65 yr, scheduled for elective modified radical mastectomy, were divided into 2 groups ( n=23 each) using a random number table method: PECS Ⅱ block-general anesthesia group (group P+ G) and PIFB-PECS Ⅱ block-general anesthesia group (group P+ P+ G). The patients received ultrasound-guided PECS Ⅱ block (P+ G group) or PIFB combined with PECS Ⅱ block (P+ P+ G group) in the pre-anesthesia room. Then the patients were admitted to the operating room, and midazolam, propofol, sufentanil and cisatracurium were used for anesthesia induction, and sevoflurane, remifentanil and cisatracurium were used for anesthesia maintenance. The intraoperative consumption of remifentanil, emergence time and extubation time were recorded. Flurbiprofen axetil 50 mg was intravenously injected as rescue analgesic after operation, and visual analog scale score was maintained ≤3 at rest. The requirement for rescue analgesia and occurrence of nausea and vomiting within 24 h after operation were recorded. Results:Compared with group P+ G, the intraoperative consumption of remifentanil was significantly decreased, the emergence time and extubation time were shortened, the rate of rescue analgesia within 24 h after operation was decreased, the time of first rescue analgesia was prolonged ( P<0.05), and no significant change was found in the incidence of nausea and vomiting in group P+ P+ G ( P>0.05). Conclusions:Compared with PECS Ⅱ block-general anesthesia, PIFB-PECS Ⅱ block-general anesthesia can reduce the amount of intraoperative opioids, inhibit postoperative hyperalgesia and promote early postoperative recovery when used for modified radical mastectomy.

ABSTRACT

Objective:To systematically evaluate the efficacy and safety of general anesthesia versus conscious sedation in patients with endovascular therapy for acute ischemic stroke.Methods:Databases, including English databases PubMed, Embase and Cochrane, as well as Chinese databases Wan Fang Data and CNKI, were screened for randomized controlled trials (RCT) of general anesthesia versus conscious sedation on the effect of endovascular treatment for acute anterior circulation ischemic stroke. The searching period was from the establishment of databases to July 14, 2022. Two researchers independently screened literatures, extracted data and evaluated the risk of bias. And meta-analysis was performed using RevMan5.3 software.Results:A total of 7 RCTs involving 923 patients were included, with 461 in the general anesthesia group and 462 in the other. As the meta-analysis showing, general anesthesia could significantly improve the good outcomes (modified Rankin Scale score≤2) at 3 months after endovascular treatment in comparison with conscious sedation ( OR=1.34, 95% CI 1.01-1.78, P=0.04), and significantly increased the rate of successful revascularization ( OR=1.87, 95% CI 1.32-2.65, P<0.001). In addition, there were no statistically significant differences between the two groups in mortality ( OR=0.93, 95% CI 0.66-1.29, P=0.65), symptomatic intracranial hemorrhage ( OR=0.88, 95% CI 0.57-1.35, P=0.55) and intervention-related complications ( OR=0.83, 95% CI 0.50-1.36, P=0.46). However, general anesthesia was associated with higher risk for both 20% reduction in mean arterial pressure ( OR=4.76, 95% CI 1.49-15.19, P=0.008) and pneumonia ( OR=2.58, 95% CI 1.51-4.39, P<0.001). Conclusions:Compared with conscious sedation, endovascular treatment under general anesthesia in patients with acute anterior circulation ischemic stroke may contribute to better outcomes and higher successful revascularization. However, this method will lead to the risk of blood pressure variability and the incidence of pneumonia.

ABSTRACT

Objective:To explore the effect of spontaneous breathing during induction of general anesthesia on atelectasis in patients undergoing laparoscopic resection of gastrointestinal tumors.Methods:A total of 60 patients aged 18-60 years scheduled for laparoscopic resection of gastrointestinal tumors under general anesthesia in the First Hospital of Shanxi Medical University from October 2021 to August 2022 were selected. The body mass index was 18.5-28.0 kg/m 2 and the American Society of Anesthesiology grade wasⅠ-Ⅱ. All patients were divided into the spontaneous breathing group (group S, 30 cases) and the controlled breathing group (group C, 30 cases) according to the random number table method. Patients in group S received 0.2-0.3 mg/kg etomidate (pumping at the speed of 200 ml/h) and 2 μg/kg remifentanil (slowly injected more than 30 s) for anesthesia induction; patients in group C received 0.2-0.3 mg/kg etomidate and 2 μg/kg remifentanil (slowly injected more than 30 s) and 0.2 mg/kg cisatracurium. After bispectral index (BIS) decreased to 80, the patients had no response to the language stimulation; and then the mask was used to closely fit the face and maintain spontaneous breathing in group S; patients in group C received manual positive pressure ventilation. Atelectasis scores were collected immediately after endotracheal intubation (T 1) and 15 min after transferring to the recovery room (T 3), and oxygenation index (OI) was collected 5 min after endotracheal intubation (T 2) and at T 3. The postoperative pulmonary complication (PPC) on the 3rd day after the operation was recorded. Results:A total of 56 patients were finally enrolled, 27 cases in group S and 29 cases in groups C. Compared with group C, the atelectasis score of group S at T 1 and T 3 decreased [T 1: (2.4±0.8) scores vs. (4.2±0.7) scores, t = -9.12, P < 0.001; T 3: (8.2±1.8) scores vs. (10.5±1.6) scores, t = -4.96, P < 0.001]. The OI increased at T 2 and T 3 in group S [T 2: (334±11) mmHg (1 mmHg = 0.133 kPa) vs. (323±13) mmHg, t = 3.45, P = 0.001; T 3: (362±23) mmHg vs. (347±25) mmHg, t = 2.31, P = 0.025]. The incidence of PPC was 20.7% (6/29) and 18.5% (5/27), respectively in group C and group S on the 3rd day after the operation, and the difference was statistically significant ( χ2 = 0.04, P = 0.838). Conclusions:Maintaining spontaneous breathing during induction of general anesthesia can reduce atelectasis caused by general anesthesia and improve oxygenation for patients undergoing laparoscopic resection of gastrointestinal tumors.
