Impact of Palonosetron on Cough Suppression in Females Undergoing Sevoflurane-Remifentanil Anesthesia for Laparoscopic Cholecystectomy: A Randomized Trial.

ABSTRACT: Remifentanil has been used to suppress peri-extubation cough. Palonosetron, a 5-HT₃ receptor antagonist, is an effective antiemetic, and 5-HT receptors mediate the cough reflex. We assessed the impact of palonosetron on effect-site concentration (Ce) of remifentanil for preventing emergence cough in females. Forty-five female patients undergoing laparoscopic cholecystectomy randomly received 0.075 mg of palonosetron (n = 21) or normal saline (n = 24) intravenously at the end of surgery. The remifentanil Ce for 50% (EC₅₀) and for 95% (EC₉₅) of patients were estimated via Dixon's up-and-down method or isotonic regression. Using Dixon's method, EC₅₀ in the control group (1.33 ± 0.38 ng/mL) was comparable to that of the palonosetron group (1.42 ± 0.75 ng/mL) (p = 0.813). Using isotonic regression, EC₅₀ (83% CIs) and EC₉₅ (95% CIs) did not reveal significant differences between the control and the palonosetron groups (1.17 (0.86-1.43) and 1.90 (1.45-1.96) ng/mL and 0.88 (0.78-1.23) and 2.43 (1.94-2.47) ng/mL, respectively). No difference was found in the remifentanil Ce to suppress emergence cough in the palonosetron group compared with the control group. It may indicate no effect of palonosetron on antitussive activity of remifentanil.

Effect-site concentration of remifentanil for smooth emergence from sevoflurane anesthesia in patients undergoing endovascular neurointervention.

Project description:During emergence from general anesthesia, coughing caused by the endotracheal tube frequently occurs and is associated with various adverse complications. In patients undergoing endovascular neurointervention, achieving smooth emergence from general anesthesia without coughing is emphasized since coughing is associated with intracranial hypertension. Therefore, the up-and-down method was introduced to determine the effective effect-site concentration (Ce) of remifentanil to prevent coughing in 50% and 95% (EC50 and EC95) of patients during emergence from sevoflurane anesthesia for endovascular neurointervention. A total of 43 participants, American Society of Anesthesiologists class I or II participants, aged from 20 to 70 years who were undergoing endovascular neurointervention through transfemoral catheter for cerebrovascular disease were enrolled. Using the up-and-down method with isotonic regression, the EC50 and EC95 of remifentanil to prevent coughing during emergence from sevoflurane anesthesia were determined. We also investigated differences of hemodynamic and recovery profiles between the cough suppression group and the cough group. In total, 38 of 43 patients were included for estimation of EC50 and EC95. The EC50 and EC95 of remifentanil to prevent coughing were 1.42 ng/mL (95% confidence interval [CI], 1.28-1.56 ng/mL) and 1.70 ng/mL (95% CI, 1.67-2.60 ng/mL), respectively. There was comparable emergence and recovery data between the cough suppression group (n = 22) and the cough group (n = 16). However, the Ce of remifentanil and total dose of remifentanil were significantly higher in the cough suppression group (P = 0.002 and P = 0.004, respectively). Target-controlled infusion of remifentanil at 1.70 ng/mL could effectively prevent extubation-related coughing in 95% of neurointervention patients, which could ensure smooth emergence.

Type of anesthesia and quality of recovery in male patients undergoing lumbar surgery: a randomized trial comparing propofol-remifentanil total i.v. anesthesia with sevoflurane anesthesia.

Project description:BackgroundPrevious studies have shown that women achieve a better quality of postoperative recovery from total intravenous anesthesia (TIVA) than from inhalation anesthesia, but the effect of anesthesia type on recovery in male patients is unclear. This study therefore compared patient recovery between males undergoing lumbar surgery who received TIVA and those who received sevoflurane anesthesia.MethodsEighty male patients undergoing elective one- or two-level primary transforaminal lumbar interbody fusion (TLIF) were randomly divided into two groups: the TIVA group (maintenance was achieved with propofol and remifentanil) or sevoflurane group (SEVO group: maintenance was achieved with sevoflurane and remifentanil). The quality of recovery-40 questionnaire (QoR-40) was administered before surgery and on postoperative days 1 and 2 (POD1 and POD2). Pain scores, postoperative nausea and vomiting, postoperative hospital stay, anesthesia consumption, and adverse effects were recorded.ResultsThe QoR-40 scores were similar on the three points (Preoperative, POD1 and POD2). Pain scores were significantly lower in the SEVO group than in the TIVA group on POD1 (30.6 vs 31.4; P = 0.01) and POD2 (32 vs 33; P = 0.002). There was no significant difference in the postoperative hospital stay or complications in the postanesthesia care unit between the TIVA group and the SEVO group.ConclusionsThis study demonstrates that the quality of recovery is not significantly different between male TLIF surgery patients who receive TIVA and those who receive sevoflurane anesthesia. Patients in the TIVA group had better postoperative analgesic effect on POD2.Trial registrationThis was registered at http://www.chictr.org.cn (registration number ChiCTR-IOR-16007987, registration date: 24/02/2016).

The neuromuscular effects of rocuronium under sevoflurane-remifentanil or propofol-remifentanil anesthesia: a randomized clinical comparative study in an Asian population.

Project description:We conducted a prospective, randomized, multicenter study to evaluate the differences in the blocking effect of different doses of rocuronium between sevoflurane- or propofol-remifentanil anesthesia in an Asian population.A total of 368 ASA I-II patients was enrolled. Anesthesia was induced with 2.0 mg/kg propofol and 0.1 μg/kg/min remifentanil (TIVA) or 5.0 vol.% sevoflurane with 0.1 μg/kg/min remifentanil (SEVO). Tracheal intubation was facilitated at 180 s after the administration of rocuronium at 0.3, 0.6, or 0.9 mg/kg and then intubation condition was evaluated. The time to maximum block and recovery profile were monitored by TOF stimulation of the ulnar nerve and by recording the adductor pollicis response using acceleromyography.The numbers of patients with clinically acceptable intubation conditions were 41, 82, and 97 % (TIVA) and 34, 85, and 90 % (SEVO) at each dose of rocuronium, respectively. There were no significant differences in the time to maximum block between groups at each rocuronium dose. There were significant differences in the recovery to a train-of-four ratio of 90 % between the groups: 42.7 (19.5), 74.8 (29.9), and 118.4 (35.1) min (TIVA) and 66.5 (39.3), 110.2 (43.5), and 144.4 (57.5) min (SEVO) at 0.3, 0.6, and 0.9 mg/kg, respectively (P < 0.001).There are no significant differences in intubation conditions between propofol-remifentanil and sevoflurane-remifentanil anesthesia at the same dose of rocuronium. The type of anesthetic does not significantly influence the time to maximum block by rocuronium. Rocuronium at a dose of 0.9 mg/kg should be used for better intubation conditions with both anesthesia regimens in an Asian population.UMIN-CTR Clinical Trial ( http://www.umin.ac.jp/ctr/index.htm ; UMIN#000007289 ; date of registration 14(th) February 2012).

Desflurane anesthesia worsens emergence agitation in adult patients undergoing thyroid surgery compared to sevoflurane anesthesia.

Project description:BackgroundThe effect of volatile anesthetics on emergence agitation in adults remains unclear. We compared the degree of emergence agitation between desflurane and sevoflurane anesthesia in adults undergoing thyroid surgery.FindingsOne hundred and sixteen patients with American Society of Anesthesiologists status 1 or 2 were randomized into two groups: the desflurane group (group D) and the sevoflurane group (group S). After induction of anesthesia with fentanyl (1-2 μg/kg) and propofol (1.5-2.5 mg/kg), tracheal intubation was facilitated with suxamethonium (0.5-1.0 mg/kg). In group D, anesthesia was maintained with desflurane in 66% nitrous oxide and 33% oxygen supplemented with fentanyl when necessary; in group S, sevoflurane was used instead of desflurane. After the end of the surgery, emergence agitation was evaluated with a modified pediatric anesthesia emergence delirium scale (ranging from 0 to 16, with higher scores indicating more severe emergence agitation) before extubation. Time to extubation from the end of the surgery, postoperative pain (evaluated by a numerical rating scale [NRS]), and postoperative nausea and vomiting (PONV) after surgery were examined. The degree of emergence agitation was more severe in group D than in group S (median [interquartile range]: 5 [4-7] vs 4 [2-6], p = 0.008). Time to extubation, NRS scores, and PONV rates were similar between the two groups.ConclusionsDesflurane anesthesia worsened emergence agitation as compared with sevoflurane in adult patients undergoing thyroid surgery, but did not affect time to extubation, postoperative pain, or PONV.Trial registrationUMIN000014215.

Remifentanil added to sufentanil-sevoflurane anesthesia suppresses hemodynamic and metabolic stress responses to intense surgical stimuli more effectively than high-dose sufentanil-sevoflurane alone.

Project description:BackgroundEven extremely high-doses of the potent opioid, sufentanil, cannot reliably suppress stress responses to intense surgical stimuli such as sternotomy. The chemically related opioid remifentanil with its different pharmacokinetics and binding affinities for delta- and kappa-opioid receptors might be more effective in attenuating these responses.MethodsASA I-III patients scheduled for a surgical procedure with sternotomy under balanced anesthesia (sevoflurane and sufentanil 3 ?g.kg(-1) bolus, 0.017 ?g.kg(-1).min(-1) infusion) were randomized into two groups. Patients in the study group were supplemented with remifentanil (2 ?g.kg(-1) bolus, 2-7 ?g.kg(-1).min(-1) infusion) starting ten minutes before sternotomy. Heart rate, arterial blood pressures, cardiac index, ejection fraction, systemic vascular resistance index (SVRI), total body oxygen uptake (VO2) and electric dermal response were measured and compared between the groups.Results62 patients were studied (study group 32, control group 30). Systolic and mean arterial blood pressures, SVRI, VO2 and skin conductance increased during sternotomy and sternal spread in the control group but not in the study group. Systolic blood pressure increase: 7.5?±?19 mmHg vs. -3.4?±?8.9 (p?=?0.005); VO2 increase: 31?±?46% vs. -0.4?±?32%; incidence of systolic blood pressure increase greater than 15 percent: 20% vs. 3% (p?=?0.035) (control vs. study group).ConclusionHigh-dose remifentanil added to sevoflurane-sufentanil anesthesia suppresses the sympathoadrenergic response to sternotomy and sternal spread better than high-dose sufentanil alone.Trial registrationClinical trial numberDRKS00004327, August 31, 2012.

Comparing laparoscopic cholecystectomy in patients with chronic obstructive pulmonary disease under spinal anesthesia and general anesthesia.

Project description:Epidemiological data demonstrate that the worldwide prevalence of chronic obstructive pulmonary disease is increasing. These patients have an increased risk of mortality and morbidity and have constant limitations in airflow. Comparing laparoscopic cholecystectomy (LC) in patients with chronic obstructive pulmonary disease (COPD) under spinal anesthesia (SA) and general anesthesia (GA).We prospectively evaluated COPD patients who underwent laparoscopic cholecystectomy under general anesthesia (Group 1, n?=?30) or spinal anesthesia (Group 2, n?=?30) in our clinic between January 2016 and January 2018. Patients with COPD were further divided into groups according to their preoperative stages (Stage 1-4). Intraoperative vital findings, postoperative pain, complications, and length of hospitalization were compared between the general (GA) and spinal anesthesia (SA) groups.The mean age of the patients in the GA group was 61.0?±?6.7 years and was 61.0?±?7.7 years in the SA group. In the GA and SA groups, the mean ASA score was 2.8?±?0.6 and 2.9?±?0.6, respectively, the mean operation duration was 31.7?±?5.1 and 30.6?±?5.1 min, respectively, and the length of hospitalization was 3.2?±?1.7 and 1.5?±?0.5 days, respectively. The partial carbon dioxide rates (PaCO2) at the postoperative 5th and 20th minutes were lower in the SA group than in the GA group. Further, the requirement for postoperative analgesia was lower in the SA group, and the length of hospitalization was significantly shorter in the SA group. There was no significant difference between the two groups in terms of operation duration.Laparoscopic cholecystectomy is a rather safe procedure for COPD patients under general and spinal anesthesia. However, spinal anesthesia is preferred over general anesthesia as it has better postoperative analgesia and causes no impairment of pulmonary functions.

Bronchospasm in obese patients undergoing elective laparoscopic surgery under general anesthesia.

Project description:BACKGROUND:Existing data suggest that obesity correlates with airway hyper-reactivity. However, the incidence of bronchospasm during bariatric surgery in obese patients has not been well studied. METHODS:This was a prospective observational study comparing 50 obese versus 50 non obese patients undergoing elective laparoscopic surgery over a 2 year period. Bronchospasm was detected clinically by auscultation and was confirmed by measuring peak airway pressure during mechanical ventilation. Blood gases were measured at predetermined time intervals intraoperatively. Categorical variables were analyzed using Fisher's exact test, while numerical variables within and between groups were compared using repeated measures general linear model. RESULTS:The incidence of bronchospasm was significantly higher in obese compared to non obese patients (P = 0.027). Peak airway pressures and blood gases differed significantly when comparing non obese patients versus obese patients without bronchospasm versus obese patients with bronchospasm. Hypoventilation resulting in gradual increase of arterial PaCO2 was noted in all groups during surgery. CONCLUSION:The incidence of bronchospasm is higher in obese patients compared to non obese patients undergoing elective laparoscopic surgery. Airway pressures and blood gas values in obese patients are somewhere between values in non obese patients and values in patients with bronchospasm, thereby implying that obesity is associated with a state where bronchial smooth muscles are not fully relaxed. Consideration of increased airway reactivity in obese patients undergoing laparoscopic surgery is important for improved patient care and uneventful anesthetic course.

Single-Incision Laparoscopic Cholecystectomy Using Conventional Laparoscopic Instruments and Comparison with Three-Port Cholecystectomy.

Project description:Single-incision laparoscopic surgery also known as laparo-endoscopic single-site surgery for cholecystectomy is performed using a single umbilical skin incision through which a laparoscope and two instruments are introduced. It is virtually a "scarless" surgery. The present study was undertaken to evaluate the efficacy of single-incision laparoscopic cholecystectomy using conventional instruments and compare it with three-port laparoscopic cholecystectomy. Thirty patients who underwent single-incision cholecystectomy were compared to an equal number of patients who underwent three-port cholecystectomy. Both groups were assessed on the basis of operative time, intraoperative complications, postoperative pain, ambulation, hospital stay, and body image at first and third week. Single-incision cholecystectomy had the advantage of less postoperative pain, early ambulation, and better body image as compared to three-port cholecystectomy; the results being statistically significant. There was no statistically significant difference in operative time and hospital stay between the two groups. Single-incision laparoscopic cholecystectomy using conventional instruments is a safe and effective surgery. It gives better cosmetic results, almost scarless surgery, without increasing the cost of surgery.

Remifentanil-based propofol-supplemented vs. balanced sevoflurane-sufentanil anesthesia regimens on bispectral index recovery after cardiac surgery: a randomized controlled study.

Project description:BackgroundThe present study was to compare the potential impact of remifentanil-based propofol-supplemented anesthesia regimen vs. conventional sevoflurane-sufentanil balanced anesthesia on postoperative recovery of consciousness indicated by bispectral index (BIS) values in patients undergoing cardiac surgery.MethodsPatients undergoing cardiac surgery were randomly allocated to get the remifentanil-based propofol-supplemented anesthesia employing target-controlled infusion (TCI) of remifentanil and propofol (Group-PR, n = 15) or a balanced-anesthesia employing sevoflurane-inhalation and TCI-sufentanil (Group-C, n = 19). In Group-PR, plasma concentration (Cp) of TCI-remifentanil was fixed at 20 ng/ml, and the effect-site concentration of TCI-propofol was adjusted within 0.8-2.0 ?g/ml to maintain BIS value of 40-60. In Group-C, sevoflurane dosage was adjusted within 1-1.5 minimum alveolar concentration to maintain BIS of 40-60, and Cp of TCI-sufentanil was fixed at 0.4 ng/ml. The inter-group difference in the time for achieving postoperative BIS > 80 (T-BIS80) in the intensive care unit was determined as the primary outcome. The inter-group difference in the extubation time was determined as the secondary outcome.ResultsT-BIS80, was shorter in Group-PR than Group-C (121.4 ± 64.9 min vs. 182.9 ± 85.1 min, respectively; the difference of means -61.5 min; 95% CI -115.7 to -7.4 min; effect size 0.812; P = 0.027). The extubation time was shorter in Group-PR than in Group-C (434.7 ± 131.3 min vs. 946.6 ± 393.3 min, respectively, P < 0.001).ConclusionsCompared with the conventional sevoflurane-sufentanil balanced anesthesia, the remifentanil-based propofol-supplemented anesthesia showed significantly faster postoperative conscious recovery in patients undergoing cardiac surgery.
