ABSTRACT
Objective:To investigate the effect of intravenous anesthesia on the detection rate of lesions in diagnostic gastroscopy.Methods:A total of 9 071 subjects who underwent diagnostic gastroscopy at the Digestive Endoscopy Center of Yangzhou University Affiliated Hospital from March 2021 to February 2022 were selected. Data were collected from the gastroscopy quality control system, including age, gender, examination physician, Helicobacter pylori infection, examination method, withdrawal time, number of images left, number of biopsies, biopsy site, gastroscopy diagnosis, pathological diagnosis, etc. They were divided into anesthesia group and general group based on the examination method, and propensity score matching (PSM) was performed on the two groups of subjects. Excluding confounding factors, the detection of lesion location and lesion type in two groups of subjects was analyzed; Simultaneously, univariate and multivariate logistic regression analysis was used to analyze the influencing factors of the detection rate of precancerous lesions and malignant tumors in the upper gastrointestinal tract.Results:After PSM, 1 655 subjects were included in both groups. In terms of lesion location, the detection rate of gastric body lesions in the anesthesia group was higher than that in the general group ( P<0.05), and the detection rate of esophageal lesions in the anesthesia group was lower than that in the general group ( P<0.05); In terms of lesion types, the detection rate of precancerous lesions such as gastric polyps, mucosal protrusions, mucosal atrophy, and intestinal metaplasia in the anesthesia group was higher than that in the general group (all P<0.05). The results of logistic regression analysis showed that intravenous anesthesia was an independent influencing factor for the detection rate of precancerous lesions and malignant tumors in diagnostic gastroscopy ( OR=1.338, 95% CI: 1.070-1.674, P<0.05). Conclusions:Intravenous anesthesia is an independent influencing factor for the detection rate of precancerous lesions and malignant tumors in diagnostic gastroscopy, and can improve the detection rate of upper gastrointestinal lesions.
ABSTRACT
Objective:To investigate the effects of dyclonine hydrochloride mucilage administered for oropharyngeal anesthesia on gag reflex in patients with chronic pharyngitis during gastroscopy.Methods:A total of 100 patients with chronic pharyngitis who met American Society of Anesthesiologists Classification I-II and received treatment in The First Affiliated Hospital of Ximen University from January to December 2020 were included in this study. Using the principle of voluntariness, these patients were divided into dyclonine hydrochloride mucilage (D) and control (C) groups, with 50 patients in each group. Ten minutes before anesthesia induction, patients in Group D took 10 mL of dyclonine hydrochloride mucilage in the mouth, but did not swallow it, and those in Group C were identically given equal volume of placebo. Ten minutes later, dyclonine hydrochloride mucilage or placebo was swallowed. For anesthesia induction, 20 μg Fentanyl and 2-4 mg/kg Propofol were intravenously administered. A gastroscopy examination was performed after the patient's consciousness disappeared. The patient's cough and body movement response scores during gastroscopy were recorded. Before anesthesia induction (T0), before endoscope insertion (T1), after endoscope insertion (T2), and after endoscope withdrawal (T3), mean arterial pressure and heart rate were recorded.Results:The incidence rate of cough and body movement in Group D were 20% (10/50) and 24% (12/50), which were significantly lower than 72% (36/50) and 68% (34/50) in Group C ( χ2 = 27.21, 19.49, both P < 0.001). At T1, mean arterial pressure in Group D and Group C was (62.21 ± 10.32) mmHg and (63.82 ± 10.51) mmHg(1 mmHg=0.133 kPa), respectively, which were significantly lower than (70.21 ± 13.13) mmHg and (70.91 ± 14.02) mmHg at T0 ( t = 3.15, 5.82, both P < 0.05). At T2, mean arterial pressure and heart rate in Group C were (80.13 ± 11.92) mmHg and (90.02 ± 15.63) beats/minute, respectively, which were significantly higher than (70.91 ± 14.02) mmHg and (78.75 ± 14.93) beats/minute at T0 in the same group ( t = 5.99, 4.03, both P < 0.05) and were also significantly higher than (66.21 ± 12.33) mmHg and (76.53 ± 10.31) beats/minute] at T2 in Group D ( t = 2.07, 2.67, both P < 0.05). Conclusion:Dyclonine hydrochloride mucilage administered for oropharyngeal anesthesia can effectively suppress gag reflex in patients with chronic pharyngitis and increase hemodynamic stability during gastroscopy.
ABSTRACT
Abstract Introduction: Healthcare costs are increasing against the backdrop of scarce resources. Surgical procedures are an important part of healthcare spending, and the cost of anesthetic techniques is relevant as part of the total cost of care and it is a potential target for expenditure optimization. Although important economic differences have been reported internationally for general anesthesia options, there are no publications in Colombia that compare current costs and allow for informed and financially responsible decision-making. Objective: To quantify and compare direct costs associated with the various general anesthesia options most frequently used at the present time. Methods: Cost minimization analysis based on a theoretical model of balanced general anesthesia using isoflurane, sevoflurane, desflurane in combination with remifentanil, and TIVA (propofol and remifentanil). Initial results were obtained using a deterministic simulation method and a sensitivity analysis was performed using a Monte Carlo simulation. Results: The average total cost per case for the different anesthetic techniques was COP 126381 for sevoflurane, COP 97706 for isoflurane, COP 288605 for desflurane and COP 222 960 for TIVA. Conclusions: Balanced general anesthesia with desflurane is the most costly alternative, 1.2 times more expensive than TIVA, and 2 and 3 times more costly than balanced anesthesia with sevoflurane and isoflurane, respectively. TIVA ranks second with a cost 1.8 times higher than balanced anesthesia with sevoflurane and 2.5 times higher than balanced anesthesia with isoflurane.
Resumen Introducción: Los costos de la atención en salud son crecientes y se enfrentan a un escenario de recursos escasos. La realización de procedimientos quirúrgicos hace parte importante de la atención y del gasto en salud, el costo de las técnicas anestésicas utilizadas es relevante en el costo total de la atención y es un objetivo potencial para la optimización del gasto. Aunque a escala internacional se han reportado diferencias económicas importantes entre las alternativas para anestesia general, en Colombia no se cuenta con publicaciones que comparen los costos actuales y permitan una toma de decisiones informada y responsable económicamente. Objetivo: Cuantificar y comparar los costos directos para Colombia de las diferentes alternativas para anestesia general usadas con más frecuencia en la actualidad. Métodos: Análisis de minimización de costos basado en un modelo teórico de anestesia general balanceada con isoflurano, sevoflurano, desflurano en combinación con remifentanilo y TIVA (propofol y remifentanilo). Se obtuvieron resultados iniciales utilizando una simulación con un método determinista y se realizó un análisis de sensibilidad con una simulación de Montecarlo. Resultados: El costo total promedio por caso para las diferentes técnicas anestésicas fue de COP 126.381 para sevoflurano, COP 97.706 para isoflurano, COP 288.605 para desflurano y COP 222.960 para TIVA. Conclusiones: La anestesia general balanceada con desflurano es la alternativa de mayor costo, es 1,2 veces más costosa que la TIVA, y 2 y 3 veces más que la balanceada con sevoflurano e isoflurano, respectivamente. La TIVA ocupa el segundo lugar con un costo 1,8 veces superior a la balanceada con sevoflurano y 2,5 veces a la balanceada con isoflurano.

Objective:To evaluate the anesthetic efficacy of remiazolam combined with alfentanil in the patients undergoing painless gastroscopy.Methods:A total of 400 patients of both sexes, aged 20-64 yr, with body mass index of 18-30 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ, scheduled for elective painless gastroscopy, were divided into 2 groups ( n=200 each) using the computer-generated random numbers: remimazolam combined with alfentanil group (group RA) and propofol combined with alfentanil group (group PA).All subjects inhaled oxygen and were denitrogenated by deep inhalation.Alfentanil 7 μg/kg and remimazolam 0.2 mg/kg were intravenously injected in group RA, and alfentanil 7 μg/kg and propofol 1.5 mg/kg were intravenously injected in group PA.When body movement occurred during operation, remimazolam 2.5 mg was intravenously injected in group RA, propofol 0.5 mg/kg was intravenously injected in group PA, and anesthesia was defined as failure when there was still body movement after 3 times of additional injection within 15 min.The success of anesthesia, effective time of sedatives, time of gastroscopy, emergence time, perioperative adverse reactions, and satisfaction score of endoscopic surgeons-anesthesiologists-patients were assessed using visual analog scale score. Results:Compared with group PA, the incidence of hypotension (6.2%/14.0%), bradycardia (6.2%/19.0%), respiratory depression (3.1%/8.0%), injection pain (2.1%/30.0%), postoperative nausea (6.3%/25.0%), fatigue (7.8%/14.0%) was significantly decreased, and the incidence of hiccup (8.3%/1.0%) and patient′ s satisfaction score were increased in group RA ( P<0.05).There was no significant difference between the two groups in the success rate of sedation, effective time of sedatives, time of gastroscopic examination, emergence time, satisfaction scores of anesthesiologists-endoscopic surgeons, and incidence of postoperative vomiting, dizziness, and lethargy ( P>0.05). Conclusions:Compared with conventional anesthesia for painless gastroscopy, remiazolam (0.2 mg/kg) combined with alfentanil (7 μg/kg) has a certain optimization effect in anesthesia for gastroscopy.
ABSTRACT
Objective:To explore the clinical effect of different flow rates of transnasal humidified rapid-insufflation ventilatory exchange (Thrive) on hypoxic events during painless gastroscopy.Methods:Patients who underwent painless gastroscopy in Nanjing First Hospital from April to July 2020 were randomly selected by random number table method and assigned to Thrive groups of 30 L/min ( n=52), 50 L/min ( n=55) and 70 L/min ( n=54). The incidences of different degree of hypoxic events (including subclinical respiratory depression, hypoxia and severe hypoxia) and adverse events related to Thrive were recorded. Results:The total incidence of hypoxic events in the 70 L/min group was 0 (0/54), which was significantly lower than that in the 30 L/min group (21.3%, 11/52, χ2=12.75, P<0.001) and 50 L/min group (12.7%, 7/55, P=0.007). There were no significant differences in subclinical respiratory depression [13.5% (7/52) VS 5.5% (3/55), χ2=1.19, P=0.194] or hypoxia [7.7% (4/52) VS 7.3% (4/55), P=0.610] between 30 L/min group and 50 L/min group. No severe hypoxia occurred in any group. The oxygenation of patients with hypoxemia in 30 L/min and 50 L/min groups was improved (SpO 2>95%) after opening the airway by mandibular support. In addition, there were no significant differences in the incidence of adverse events except hypoxemia among the three groups ( P>0.05). Conclusion:The flow rates of Thrive of 30 L/min, 50 L/min, and 70 L/min can prevent the occurrence of severe hypoxia during painless gastroscopy, and the flow rate of 70 L/min can further reduce the incidence of subclinical respiratory depression.
ABSTRACT
Objective:To investigate the analgesic effect of intravenous anesthesia induction combined with anterior quadratus lumborum block (AQLB)and related hemodynamic changes in patients undergoing laparoscopic retroperitoneal partial nephrectomy (RPN).Methods:A total of 116 patients undergoing elective laparoscopic partial nephrectomy for renal tumors in Jinhua Central Hospital from August 2021 to February 2022 were randomly divided into two groups with 58 cases in each group. Patients in control group received intravenous anesthesia , while those in study group received intravenous anesthesia induction with AQLB. The analgesic effect was evaluated at 1, 6, 12, 24, and 48 h after the operation. The hemodynamics were monitored at the time of entering the operating room (T 0), 3 min after induction of anesthesia (T 1), at the beginning of the operation (T 2), after the operation (T 3), and leaving the operating room (T 4). Microcirculation was assessed at 1, 6, 12, 24, and 48 h after operation. Cognitive function was assessed 30min before anesthesia, 6 h, 24 h, and 72 h after operation. Results:At 1, 6, 12, 24 and 48 h after operation, the visual analogue scale (VAS) of the resting (quiet state) pain in the study group were 3.2±1.2, 2.6±0.3,2.0±0.4, 1.5±0.4 and 0.8±0.2, which were significantly lower than those in control group (4.0±1.7, 3.4±0.7, 2.9±0.5, 1.7±0.5 and 1.2±0.3) ( t=2.93, P=0.004; t=8.00, P<0.001; t=10.07, P<0.001; t=2.38, P=0.019; t=8.45, P<0.001). There was no significant difference in heart rate and mean arterial pressure (MAP) at T 0 between two groups ; no significant difference in the heart rate at T 1, T 2, T 3 and T 4. There were significant differences in MAP levels at T 1, T 2, T 3 and T 4 between study group [(80.0±8.0)mmHg (1 mmHg=0.133 kPa), (84.4±8.4)mmHg, (80.4±5.7)mmHg, (86.4±4.7)mmHg and control group (77.1±7.5)mmHg, (88.0±8.6)mmHg, (83.0±7.7)mmHg, (92.2±6.2) mmHg; t=2.01, P=0.046; t=2.28, P=0.024; t=2.07, P=0.041; t=5.68, P<0.001]. At 6, 12, 24 and 48 h after operation, the morphological scores of tube loops in the study group were 1.0±0.2, 0.8±0.2, 0.7±0.1 and 0.7±0.1, which were lower than those in the control group (1.1 ±0.2, 0.9±0.2, 0.8±0.2 and 0.8±0.1; t=2.69, P=0.008; t=2.69, P=0.008; t=3.41, P=0.001; t=5.39 , P < 0.001). The blood flow status scores of the study group were 1.1±0.2, 0.9±0.2, 0.8±0.2 and 0.6±0.1, which were lower than those of the control group (1.2±0.2, 1.0±0.2, 0.9±0.2 and 0.7±0.1; t=2.69, P=0.008; t=2.69, P=0.008; t=2.69, P=0.008; t=5.39, P<0.001). The cognitive function scores of the study group and the control group were 24.4±1.0, 27.1±0.9 and 23.5±0.9, 26.7±0.9 at 6 h and 24 h after operation ( t=5.10, P<0.001; t=2.39, P=0.018); while there were no significant at 72 h after operation between two groups (28.2±0.9 vs. 28.1±0.8, t=0.63, P=0.529). Conclusion:Intravenous anesthesia induction combined with anterior quadratus lumborum block has a good analgesic effect in patients undergoing RPN, with stable hemodynamics and microcirculation, and not affecting cognitive function of patients.
ABSTRACT
Objective:To evaluate the relationship between early postoperative recovery and frailty after digestive endoscopy-assisted minimally invasive surgery under intravenous anesthesia in the elderly.Methods:This study retrospectively selected hospitalized patients, aged ≥65 yr, scheduled for elective gastrointestinal endoscopic treatment.Early postoperative recovery time was defined as the period from the end of propofol administration to the achievement of a modified Aldrete score of 9.All the patients were divided into 2 groups according to whether the early recovery time after operation was less than 75%: normal early postoperative recovery time group and delayed early postoperative recovery time group.Frailty was assessed using the frailty phenotype (FP score 0-5), and the patient was diagnosed as frail (FP ≥3) or non-frail (FP 0-2). The age, sex, height, weight, smoking history, American Society of Anesthesiologists (ASA) Physical Status classification, type of operation, and baseline mean arterial pressure and heart rate were recorded.Logistic regression analysis was used to identify the risk factors for delayed early postoperative recovery time after minimally invasive digestive endoscopy under intravenous anesthesia in elderly patients.Results:A total of 214 patients were enrolled and divided into normal early postoperative recovery time group ( n=169) and delayed early postoperative recovery time group ( n=45). There were significant differences in frailty, age, drinking history of more than 10 yr, preoperative ASA Physical Status classification and propofol administration time between delayed early postoperative recovery time group and normal early postoperative recovery time group ( P<0.05). The results of logistic regression analysis indicated that frailty, age, ASA Physical Status classification Ⅲ, and propofol administration time were independent risk factors for the occurrence of delayed early postoperative recovery ( P<0.05). Conclusions:Frailty, age, ASA Physical Status classification Ⅲ and propofol administration time are independent risk factors for delayed early postoperative recovery time following digestive endoscopy-assisted minimally invasive surgery under intravenous anesthesia in elderly patients.
ABSTRACT
Objective:To investigate the efficacy and safety of naborphine versus dezocine in painless visual anesthetics induced abortion. Methods:A total of 120 patients who underwent painless visual anesthetics induced abortion in Zhongshan City People's Hospital and Zhongshan Shaxi Longdu Hospital, China during January to September in 2020. They were randomly assigned to receive intravenous naborphine hydrochloride injection (0.15 mg/kg, naborphine group) or dezocine injection (5 mg, dezocine group), followed by intravenous propofol (2 mg/kg). When the eyelash reflex disappeared, surgery was initiated. If there were body movements, 30-50 mg propofol was added as appropriate. Systolic blood pressure, diastolic blood pressure, blood oxygen saturation, and heart rate before anesthesia (T 0), at 3 minutes after the beginning of surgery (T 1), and during recovery (T 2) were compared between the two groups. The time to regain consciousness, postoperative visual analogue pain score, propofol dose, operative time, and adverse reactions were determined in each group. Results:There were slight, but not significant, differences in systolic blood pressure and heart rate between the two groups at T 0, T 1 and T2 (all P > 0.05). There were no significant differences in time to regain consciousness, postoperative visual analogue pain score, propofol dose and operative time between the two groups (all P > 0.05). The incidence of nausea and vertigo in the naborphine group was 8.3% (5/60) and 11.6% (7/60), respectively, which was significantly lower than that in the dezocine group [30.0% (18/60), 31.6% (19/60), χ2 = 9.09, 7.07, both P < 0.05). Conclusion:Naborphine combined with propofol for painless visual anesthetics induced abortion exhibits good anesthetic effects and safety, with fewer intraoperative and postoperative adverse reactions than dezocine combined with propofol.
ABSTRACT
Objective:To investigate the effects of dexmedetomidine on hemodynamics, quality of recovery from anesthesia and postoperative analgesia in children patients with hernia subjected to laparoscopic hernia repair.Methods:A total of 120 children patients who received laparoscopic hernia repair in Shangyu Maternal and Child Health Hospital from March 2019 to March 2020 were included in this study. They were randomly assigned to receive anesthesia maintenance with either inhaled sevoflurane (control group, n = 60) or intravenous dexmedetomidine hydrochloride (observation group, n = 60). The hemodynamic changes at different time points [5 minutes before skin incision (T0), 5 minutes after skin incision (T1) and 15 minutes after skin incision (T2)] were compared between the control and observation groups. Time to extubation, time to recovery from anesthesia, time to wake up, occurrence of agitation, and duration of agitation were compared between the two groups. Visual Analogue Scale score at 3, 12 and 24 hours after surgery were compared between the control and observation groups. Results:Mean arterial pressure and heart rate measured at T1 in the observation group were (72.01 ± 1.64) mmHg and (136.42 ± 3.20) beats/minute, respectively, which were significantly lower than those in the control group [(76.31 ± 1.89) mmHg and (143.21 ± 3.45) beats/minute, t = 13.311, 11.177, both P < 0.05]. Mean arterial pressure and heart rate measured at T2 in the observation group were (69.32 ± 1.36) mmHg and (130.02 ± 2.61) beats/minute, respectively, which were significantly lower than those in the control group [(72.02 ± 1.86) mmHg, (134.09 ± 3.26) beats/minute, t = 9.077, 7.549, both P < 0.05]. Time to extubation, time to recovery from anesthesia, and time to wake up in the observation group were (7.15 ± 0.89) minutes, (10.36 ± 1.74) minutes, (26.76 ± 8.32) minutes, respectively, which were significantly shorter than those in the control group [(9.20 ± 1.43) minutes, (8.23 ± 1.56) minutes, (39.42 ± 12.15) minutes, t = 9.428, 7.060, 6.659, P < 0.05]. The incidence of agitation in the observation group was significantly lower than that in the control group [10.00% (6/15) vs. 25.00% (15/60), χ2= 4.675, P < 0.05)]. Duration of agitation in the observation group was significantly shorter than that in the control group [(6.75 ± 1.32) minutes vs. (10.85 ± 2.14) minutes, t = 12.631, P < 0.05]. At 3, 12 and 24 hours after surgery, Visual Analogue Scale score in the observation group was (2.15 ± 0.34) points, (1.45 ± 0.38) points and (1.08 ± 0.26) points, respectively, which were significantly lower than that in the control group [(3.24 ± 0.53) points, (2.16 ± 0.39) points, (1.54 ± 0.32) points, t = 13.409, 10.100, 8.642, all P < 0.05]. Conclusion:Dexmedetomidine hydrochloride has little effect on hemodynamics during surgery in children patients with hernia subjected to laparoscopic hernia repair, with fast recovery from anesthesia, a low incidence of agitation, and obvious postoperative analgesia.
ABSTRACT
Objective:To investigate the anesthetic effects of inhalational sevoflurane versus intravenous ketamine in pediatric surgical anesthesia. Methods:A total of 100 patients with appendicitis who underwent appendectomy in Ningbo Ninth Hospital between June 2017 and August 2018 were included in this study. They were randomly assigned to receive either inhalational anesthesia with sevoflurane (observation group, n = 50) or intravenous anesthesia with ketamine (control group, n = 50). Hemodynamic indexes at different time periods (T1: 5 minutes after entering the room, T2: after anesthesia induction, T3: immediately after skin incision, T4: operation completion), anesthesia induction, duration for anesthesia induction and recovery from anesthesia, liver function, and adverse reactions were compared between the observation and control groups. Results:There was no significant difference in peripheral oxygen saturation (SpO 2) level at different time periods between the observation and control groups (all P > 0.05). At T1, there were no significant differences in mean arterial pressure and heart rate between the two groups (both P > 0.05). At T2, T3 and T4, mean arterial pressure in the observation group was (67.25 ± 1.32) mmHg, (67.52 ± 1.32) mmHg, and (66.28 ± 1.31) mmHg, respectively, and heart rate was (115.21 ± 2.32) beats/minute, (112.21 ± 1.34) beats/minute and (111.25 ± 1.32) beats/minute, respectively. There were significant differences in mean arterial pressure and heart rate measured at T2, T3 and T4 between the observation and control groups ( t = 19.176, 16.817, 30.015, 58.797, 51.649, 2.617, all P < 0.05). The time to pain reflex disappearance and the time to eyelash reflex disappearance in the observation group were (2.32 ± 0.21) minutes and (1.26 ± 0.32) minutes, respectively, which were significantly longer than those in the control group ( t = 9.247, 4.251, both P < 0.05). The time to eye opening or body movement and the time to getting out of operation room were (3.21 ± 1.32) minutes and (5.52 ± 1.13) minutes respectively, which were significantly shorter than those in the control group ( t = 91.851, 109.641, both P < 0.05). After surgery, alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase and bilirubin levels in the observation group were (26.01 ± 1.32) U/L, (22.02 ± 1.32) U/L, (486.32 ± 2.74) U/L, (0.66 ± 0.02) U/L, respectively. There were significant differences in these indexes between observation and control groups ( t = 6.036, 6.798, 23.741, 3.500, all P < 0.05). The incidence of adverse reactions in the observation group was significantly lower than that in the control group ( χ2 = 9.470, P < 0.05). Conclusion:Inhalational sevoflurane is advantageous over and safer than intravenous ketamine in pediatric surgical anesthesia.
ABSTRACT
Objective:To investigate the effect of two different withdrawal sequences on the quality of recovery in patients undergoing nasal endoscopic surgery under combined intravenous and inhalation anesthesia.Methods:Seventy patients scheduled for endoscopic sinus surgery in The First Affiliated Hospital of Xiamen University, China from January to June 2019 were included in this study and randomly assigned to undergo intravenous anesthesia alone (Group A, n = 35) or combined intravenous and inhalation anesthesia (Group B, n = 35). Propofol 2-4 mg/kg, fentanyl 3-4 μg/kg, cisatracurium besylate 0.2 mg/kg were used to induce anesthesia. Propofol 4-6 mg/kg/h, remifentanil 6.5-13.0 mg/kg/h, sevoflurane ≥ 0.30 minimum alveolar concentration were used to maintain anesthesia. At 30 minutes before the end of surgery, inhalational sevoflurane administration and pump propofol administration were stopped in the groups A and B respectively. At 10 minutes before the end of surgery, pump propofol administration and inhalational sevoflurane administration were stopped in the groups A and B respectively. At the end of surgery, pump remifentanil administration was stopped in both groups A and B. The time to spontaneous breathing recovery, the time to consciousness recovery, and the time to tracheal extubation were recorded. Mean arterial pressure and heart rate were recorded at the time of entering the operation room (T0), at the end of anesthesia (T1), at the time of spontaneous breathing recovery (T2), consciousness recovery (T3) and tracheal extubation (T4), 5 minutes (T5) and 10 minutes after tracheal extubation (T6). Agitation score was recorded at T2-T6 and at 20 minutes after tracheal extubation (T7). Cough score was recorded at T4. Results:The time to spontaneous breathing recovery, the time to consciousness recovery, and the time to tracheal extubation in group A were (16.0 ± 4.6) minutes, (18.0 ± 5.3) minutes, (19.0 ± 5.5) minutes, respectively, which were significantly longer than (8.8 ± 3.5) minutes, (9.5 ± 4.1) minutes, (10.7 ± 4.5) minutes, respectively in the group B ( t = 9.554, 8.881, 9.011, all P < 0.05). There were no significant differences in mean arterial pressure and heart rate recorded at T0-T6 between groups A and B (all P > 0.05). There was no significant difference in agitation score measured at T3-T6 between groups A and B (all P > 0.05). There was no significant difference in cough score recorded at T4 between groups A and B ( P > 0.05). Conclusion:Two different withdrawal sequences can maintain stable hemodynamics and reduce agitation during recovery period and cough during extubation. The recovery time of remifentanil combined with propofol is longer than that of remifentanil combined with sevoflurane.
ABSTRACT
Objective:To compare the effects of intravenous anesthesia between propofol and etomidate in patients undergoing laparoscopic surgery and their effects on plasma nitric oxide (NO) and endothelin-1 (ET-1).Methods:The clinical data of 80 patients with laparoscopic surgery in Guangrao People′s Hospital from March 2017 to March 2019 were retrospectively analyzed. Among them, 40 cases were given propofol intravenous anesthesia (propofol group), and 40 cases were given etomidate intravenous anesthesia (etomidate group). The anesthetic effect, plasma NO and ET-1 levels, hemodynamic indexes and adverse reactions (muscle spasm, nausea and vomiting, injection site pain, body movement and respiratory depression) were compared between the two groups.Results:The time of consciousness disappearance, tracheal intubation, eye opening, spontaneous breathing and speech response in etomidate group were significantly shorter than those in propofol group: (57.48 ± 2.63) s vs. (86.17 ± 7.41) s, (4.39 ± 2.56) min vs. (6.42 ± 2.58) min, (5.39 ± 2.56) min vs. (9.42 ± 2.58) min, (5.21 ± 1.99) min vs. (8.75 ± 2.54) min and (8.39 ± 2.56) min vs. (8.39 ± 2.56) min, and the differences were statistically significant ( P<0.05). The levels of NO and ET-1 in the etomidate group were significantly lower than those in the propofol group at 0.5, 1.0 and 1.5 h after pneumoperitoneum ( P< 0.05). The levels of systolic blood pressure, diastolic blood pressure and oxygen saturation (SpO 2) in the etomidate group were significantly higher than those in the propofol group: (78.42 ± 4.68) mmHg (1 mmHg = 0.133 kPa) vs. (74.11 ± 6.63) mmHg, (132.86 ± 8.71) mmHg vs. (111.24 ± 3.56) mmHg and 0.982 ± 0.032 vs. 0.953 ± 0.043, and the differences were statistically significant ( P<0.05). The incidence of adverse reactions in the etomidate group was significantly lower than that in the propofol group: 17.5% (7/40) vs. 47.5% (19/40), P<0.05. Conclusions:Compared with propofol intravenous anesthesia, etomidate intravenous anesthesia in laparoscopic surgery patients has more stable hemodynamics and better anesthetic effect. It can effectively inhibit the release of NO and ET-1, and has higher safety.
ABSTRACT
Objective:To compare the effects of total intravenous anesthesia and inhalation anesthesia on early postoperative immune function, recurrence and metastasis by Meta-analysis in patients with malignant tumors.Methods:The PubMed, Embase and Cochrane Library were searched by computer from January 2010 to January 2020. The randomized controlled trials of surgical treatment using total intravenous anesthesia or inhalation anesthesia in patients with malignant tumors were collected. The RevMan 5.3 and STATA 15.0 softwares were used to analyze the impact of 2 anesthesia methods on early postoperative immune function indexes and tumor recurrence and metastasis in patients with malignant tumors. The immune function indexes included interleukin (IL)-6, IL-10, transforming growth factor (TGF)-β, vascular endothelial growth factor (VEGF)-C and natural killer (NK) cell.Results:A total of 8 articles were included, with a total of 665 patients. Meta analysis results show that, compared with inhalation anesthesia, total intravenous anesthesia could significantly reduce the levels of IL-6, TGF-β and VEGF-C in patients with malignant tumors after surgery ( SMD = - 0.35, - 0.26 and - 0.64; 95% CI - 0.58 to - 0.12, - 0.49 to - 0.02 and - 0.99 to - 0.28; P<0.01 or <0.05); the 2 anesthesia methods had no significant effect on IL-10 and NK cell in patients with malignant tumors after surgery ( SMD = 0.16 and 0.18, 95% CI - 0.07 to 0.39 and - 0.23 to 0.60, P>0.05); and the 2 anesthesia methods had no significant effect on tumor recurrence and metastasis in patients with malignant tumors ( RR = 0.70, 95% CI 0.47 to 1.03, P = 0.07). Conclusions:Total intravenous anesthesia may improve the early postoperative immune function in patients with malignant tumor by reducing the levels of pro-cancer factors IL-6, TGF-β and VEGF-C, but total intravenous anesthesia has no obvious effect on reducing postoperative tumor recurrence and metastasis in patients with malignant tumor.
ABSTRACT
RESUMEN Introducción: la anestesia general libre de opioides surge ante la necesidad de evasión del uso de opioides en el transoperatorio y sus efectos indeseados en el posoperatorio. Objetivo: evaluar el comportamiento hemodinámico y la recuperación anestésica en pacientes intervenidas mediante cirugía ambulatoria por cáncer de mama, en las cuales se administró anestesia general total intravenosa libre de opioides o general balanceada. Métodos: se realizó un estudio cuasiexperimental, prospectivo en pacientes a las que se aplicó anestesia general balanceada (n=34) y total intravenosa libre de opioides (n=34) intervenidas quirúrgicamente por cáncer de mama, en el Hospital General Docente "Abel Santamaría Cuadrado", durante el 2018. Resultados: el grupo de anestesia general balanceada mostró mayor variación intraoperatoria de los parámetros evaluados, con diferencias significativas (p=0,019). El tiempo medio de despertar fue menor en el grupo de anestesia total intravenosa (2,10 ± 0,907 min vs 5,35 ± 1,250 min; p<0,01), al igual que el dolor, con diferencia significativa (p<0,05) y el tiempo de recuperación, donde una hora después de la intervención, el 85 % cumplía los criterios de alta anestésica. El retraso en el alta de la unidad de recuperación ocurrió principalmente por el bajo nivel de actividad motora, con mayor incidencia en el grupo de anestesia general balanceada (71 % vs 26 %; p=0,00). Conclusiones: la anestesia total intravenosa libre de opioides fue superior al método general balanceado, pues mostró mayor estabilidad hemodinámica y analgesia, menor incidencia de complicaciones posoperatorias y menor tiempo de estancia en sala de recuperación posanestésica.
ABSTRACT Introduction: opioid-free general anesthesia arises from the need to avoid the use of opioids in the transoperative period and the undesirable effects in the postoperative period. Objective: to assess the hemodynamic behavior and anesthetic recovery in patients who underwent ambulatory surgery for breast cancer and those who were given either opioid-free intravenous general or balanced general anesthesia. Methods: a quasi-experimental, prospective study was carried out on patients who received balanced general anesthesia (n=34) and total opioid-free intravenous anesthesia (n=34), who underwent breast cancer surgery at Abel Santamaria Cuadrado General Teaching Hospital during 2018. Results: the group of balanced general anesthesia showed greater intraoperative variation of the parameters assessed, with significant differences (p=0.019). The mean time of awakening was lower in the intravenous total anesthesia group (2.10 ± 0,907 min vs. 5,35 ± 1,250 min; p<0.01), as was pain, with significant difference (p<0.05) and the recovery time, where one hour after the surgery, 85 % met the criteria for anesthesia discharge. The delay in discharge from the recovery unit occurred mainly because of the low level of motor activity, with a higher incidence in the group of balanced general anesthesia (71% vs. 26 %; p=0.00). Conclusions: intravenous opioid-free total anesthesia was higher to the balanced general approach because it showed greater hemodynamic and analgesic stability, lower incidence of postoperative complications, and shorter time spent in the post-anesthesia recovery room.

ABSTRACT
Objective@#To investigate the effects of two anesthetic modes on cognitive function in elderly patients undergoing laparoscopic cervical cancer resection.@*Methods@#From August 2016 to April 2018, 60 elderly patients undergoing laparoscopic cervical cancer resection in the General Hospital of Armed Police were divided into control groupand observation group according to odd and even of bed number, with 30caese in each group.Intravenous anesthesia was used in the control group, and intravenous anesthesia combined with inhalation anesthesia was used in the observation group.The anesthetic effect, MMSE score, MoCA score and the incidence of cognitive dysfunction were compared between the two groups.@*Results@#The anesthesia effect time, extubation time and recovery time of the observation group were (1.62±0.30)min, (15.68±3.26)min, (8.69±3.68)min, respectively, which were significantly shorter than those of the control group[(4.68±0.91)min, (27.46±4.03)min, (20.36±4.58)min](all P<0.05). There were no statistically significant differences in MMSE score and MoCA score between the two groups before operation (all P<0.05), and there was statistically significant difference in MMSE score between the two groups at 2 h and 6 h after operation (all P<0.05). The MMSE score in the observation group was higher than that in the control group(all P<0.05), but there was no statistically significant difference on the 1st day after operation (P>0.05). At 2 h, 6 h, 1 d after operation, the MoCA scores in the observation group were significantly higher than those in the control group (all P<0.05). The incidence of cognitive dysfunction in the observation group was 6.67%(2/30), which was significantly lower than 26.67%(8/30) in the control group (P<0.05).@*Conclusion@#Compared with intravenous anesthesia alone, intravenous anesthesia combined with inhalation anesthesia for elderly patients undergoing laparoscopic cervical cancer resection has a good anesthetic effect and can reduce the incidence of cognitive dysfunction, which is worthy of further application in clinical practice.
ABSTRACT
Objective To evaluate the effects of surgery under ketamine anesthesia during mid-pregnancy on cognitive function of offspring rats.Methods Thirty healthy pregnant Sprague-Dawley rats at14 days of gestation,aged 9-10 weeks,weighing 270-310 g,were assigned to 3 groups (n=10 each)using a random number table method:exploratory laparotomy under ketamine anesthesia group (KSgroup),ketamine anesthesia group (K group) and control group (C group).In KS group,ketamine 20mg/kg was injected via the caudal vein,and then ketamine was continuously infused at a rate of 130mg · kg-1 · h-1 after loss of right reflex to maintain anesthesia for 2 h,and exploratory laparotomy was per-formed after anesthesia was stable.Group K received no exploratory laparotomy and the other treatmentswere similar to those previously described in group KS.The equal volume of normal saline was given insteadin group C.The cliff avoidance,passive avoidance,and Morris water maze tests were used to evaluate the spatial perception and learning and memory ability of the offspring rats on postnatal days 7,23 and 30.Hippocampal tissues of rat offsprings were obtained at 24 h after the end of Morris water maze test to determine neural precursor cell-expressed developmentally downregulated protein 9 (NEDD9) and postsynaptic density 95 (PSD-95) protein and mRNA expression by quantitative polymerase chain reaction or Western blot.Results Compared with group C,the score of cliff avoidance was significantly decreased,the results of Morris water maze test showed that the escape latency was significantly prolonged,the platform-crossing times were decreased,the time spent in the second quadrant was shortened,the expression of NEDD9 and PSD-95 was down-regulated (P ＜ 0.05),and no significant changes were found in the expression of NEDD9 and PSD-95 mRNA in KS group,and no significant changes were found in the indexes mentioned above in K group (P＞0.05).There was no significant difference in the numberof errors in passive avoidance test among the three groups (P＞0.05).Conclusion Ketamine anesthesia during mid-pregnancy exerts no effect on the cognitive function of offspring rats,abdominal surgery under ketamine anesthesia impairs the spatial perception and learning and memory ability of offspring rats,and the mechanism is related to down-regulating the expression of NEDD9 and PSD-95 in hippocampi of offspring rats.
ABSTRACT
Objective@#To investigate the effect of peripheral nerve block combined with venous fast track anesthesia on elderly patients undergoing lower extremity orthopedic surgery.@*Methods@#From September 2015 to December 2017, 64 senile patients with lower extremity orthopedic surgery in the Fifth Hospital of Ningbo were selected in the research.According to the different methods of anesthesia, the patients were divided into observation group (30 cases, application of combined intravenous peripheral nerve block and fast track anaesthesia), and the control group (34 cases, application of simple intravenous general anesthesia). The heart rate, average arterial pressure, spontaneous breathing recovery time, extubation time, complication rate and cognitive function scores of the two groups were compared.@*Results@#The heart rate and average arterial pressure of T1 and T3 in the observation group were significantly lower than those in the control group (P<0.05). The spontaneous breathing recovery time[(8.32±3.26)min] and extubation time[(9.69±4.29)min] in the observation group were significantly shorter than those in the control group[(18.24±5.23)min and (27.24±4.58)min](t=8.961, 15.756, all P<0.05). The incidence rate of postoperative complications in the observation group (3.33%) was significantly lower than that in the control group (20.59%)(χ2=4.338, P<0.05). The cognitive function score of the observation group was significantly higher at 4 h and 8 h after surgery than that of the control group (t=6.745, 8.494, all P<0.05).@*Conclusion@#Peripheral nerve block combined with intravenous fast-track anesthesia is very feasible for elderly patients undergoing lower limb orthopedic surgery.The time for patients to recover from spontaneous breathing and extubation is shorter, and the risk of complications such as delirium, restlessness, nausea and vomiting is lower.
ABSTRACT
Objective@#To evaluate the feasibility and safety of maintaining general anesthesia without neuromuscular blockade in oral double-balloon enteroscopy.@*Methods@#Totally 120 patients undergoing oral double-balloon enteroscopy under general anesthesia were randomly assigned into two groups: the observation group and the control group. The observation group was not given muscle relaxants for anesthesia maintenance, while the control group was given muscle relaxants punctually. Observation indexes were monitored, including the mean arterial pressure (MAP), heart rate (HR), peak airway pressure (Ppeak) and end-tidal CO2 partial pressure (PETCO2) before anesthesia (T0), immediately after intubation (T1), at the time of endoscopy placement (T2), at the end of endoscopy withdrawal (T3), and at the time of waking-up (T4). The cases of spontaneous breathing recovery before the end of endoscopy, postoperative recovery time, extubation time, length of PACU stay, postoperative adverse reactions and satisfactory rates were recorded.@*Results@#Twelve cases were removed by the exclusion criteria, and the remaining 108 cases completed the study, including 56 cases in the observation group and 52 cases in the control group. The one-time success rate of induction was both 100% in the two groups. There were no significant differences in MAP, HR, Ppeak, and PETCO2 between the two groups at each observation point (all P>0.05), and the same is true for within group comparison with T0 (all P>0.05). The recovery rate of spontaneous respiration in the observation group was significantly higher than that in the control group [100% (56/56) VS 42% (22/52), χ2=44.73, P=0.000]. The awaken time, extubation time and length of PACU stay were 6±2 min, 10±3 min, and 11±4 min, respectively, in the observation group, compared with 15±5 min (t=-12.64, P=0.000), 17±5 min (t=-8.90, P=0.000), and 17±7 min (t=-5.73, P=0.000) in the control group. None of the patients required assisted ventilation. Hypoxemia occurred in 2 cases and nausea in 3 cases in the control group, while only nausea occurred in 1 patient in the observation group. The overall incidence of adverse reactions was not statisticaly different between the two groups (P>0.05). Anesthesia satisfaction rate of two groups was 100%.@*Conclusion@#It is feasible and safe to perform oral double-balloon enteroscopy without muscle relaxants during maintaining under general anesthesia, with quick recovery of spontaneous breathing and awakening, early extubation and less cost.
