Effects of Sevoflurane, Isoflurane and Propofol Infusions on Post-Operative Recovery Criteria in Geriatric Patients

We compared the effects of sevoflurane, isoflurane and propofol infusions on postoperative recovery criteria in geriatric patients. Sixty patients aged > 65 years, classified as American Society of Anesthesiologists (ASA) group 1 or 2 and undergoing gynaecological or urological procedures were randomized equally into three groups. Group 1 received 1 minimum alveolar concentration (MAC) sevoflurane in a 50% O2/N2O mixture and group 2 received 1 MAC isoflurane in a 50% O2/N2O mixture. Group 3 received a 50% O2/N2O mixture plus propofol total intravenous anaesthesia (8 mg/kg for the first 30 min, followed by 6 mg/kg for maintenance). Recovery criteria comprising the times to spontaneous eye opening, extubation, response to verbal stimuli and orientation were recorded following the discontinuation of anaesthesia. Recovery times were significantly shorter in groups 1 and 3 compared with group 2. We conclude that sevoflurane and propofol had similar effects on recovery criteria and were associated with a faster recovery than isoflurane.

Partial nephrectomy aims to maintain renal function by nephron sparing; however, functional changes in the contralateral kidney remain unknown. We evaluate the functional change in the contralateral kidney using a diethylene triamine penta-acetic acid (DTPA) renal scan and determine factors predicting contralateral kidney function after partial nephrectomy. A total of 699 patients underwent partial nephrectomy, with a DTPA scan before and after surgery to assess the separate function of each kidney. Patients were divided into three groups according to initial contralateral glomerular filtration rate (GFR; group 1: <30 ml·min−1·1.73 m−2, group 2: 30–45 ml·min−1·1.73 m−2, and group 3: ≥45 ml·min−1·1.73 m−2). Multiple-regression analysis was used to identify the factors associated with increased GFR of the contralateral kidney over a 4-yr postoperative period. Patients in group 1 had a higher mean age and hypertension history, worse American Society of Anesthesiologists score, and larger tumor size than in the other two groups. The ipsilateral GFR changes at 4 yr after partial nephrectomy were −18.9, −3.6, and 3.9% in groups 1, 2, and 3, respectively, whereas the contralateral GFR changes were 10.8, 25.7, and 38.8%. Age [β: −0.105, 95% confidence interval (CI): −0.213; −0.011, P < 0.05] and preoperative contralateral GFR (β: −0.256, 95% CI: −0.332; −0.050, P < 0.01) were significant predictive factors for increased GFR of the contralateral kidney after 4 yr. The contralateral kidney compensated for the functional loss of the ipsilateral kidney. The increase of GFR in contralateral kidney is more prominent in younger patients with decreased contralateral renal function.

Operational Time

Background: Cholecystectomy is a widespread abdominal procedure. A period of 8-hour-fasting for this relatively rapid surgery negatively affects the patients’ comfort. Objectives: The current study aimed to evaluate the effects of the presurgical intake of carbohydrate on patients’ comfort. Materials and Methods: This prospective study was carried out on 42 cholecystectomy patients (with the American Society of Anesthesiologists grade of I-II) divided into two groups. The patients in group 1 underwent laparoscopic cholecystectomy after an 8-hour-fasting period. The subjects in group 2 received a carbohydrate-rich solution with 12.5% dextrose before the surgery (125 g of sugar melted in 1 L of water; 800 and 200 mL 8 and 2 h before the surgery, respectively). Thirst, hunger, and nausea at the 9th preoperative hour and 30 min before the surgery in addition to nausea and vomiting at the 2nd, 8th, and 24th postoperative hours were assessed in both groups. Results: The mean age and body mass index (BMI) values of the patients were 48.38±12.68 years and 29.85±5.20 kg/m², respectively. The mean operational time was 36.5 min (range: 26-114 min). No difference was observed between the two groups in terms of age, BMI, and operational time. The investigation 30 min before cholecystectomy revealed that the rates of hungry and thirsty patients were higher in group 1, compared to those reported for group 2 (P=0.003 and P=0.032). Nevertheless, at the 2nd and 8th postoperative hours, the rate of patients complaining of nausea were higher in group 2 in comparison to that of group 1 (P=0.048 and P=0.014). Conclusions: It is suggested that the intake of carbohydrate-rich fluids up to the preoperative 2nd hour decreased presurgical hunger/thirst. The results of this study are in line with the findings of previous studies. It is believed that the intake of CHO-rich solutions up to 2 h before surgery may provide comfort by decreasing hunger/thirst. Nevertheless, it is necessary to take into account a potential rise in a feeling of nausea among these patients.

Post-operative vomiting, especially in ambulatory surgical patients, remains a troublesome problem. This placebo-controlled, randomized, prospective double-blind trial was designed to evaluate the efficacy of two prophylactic anti-emetic regimens on post-operative vomiting in 1-day thyroid surgery. Altogether 60 elective surgical patients were followed for 4 h post-operatively. All patients were American Society of Anesthesiologists physical status of I or II and aged between 22 and 60 years: group 1 was saline control; in groups 2 and 3, metoclopramide (0.2 mg/kg) or tropisetron (5 mg) was administered, respectively, as an intravenous single dose during induction. Patients were pre-medicated. A standardized anaesthetic technique consisting of thiopentone-succinylcholine for induction and fentanyl-nitrous oxide-halothane-pancuronium for maintenance of anaesthesia was used. A ‘rescue’ anti-emetic was provided in case of continued vomiting or at the patient's request. Anti-emetic inefficacy was defined as request for rescue anti-emetic and/or vomiting episode during the first 4 h post-operation. The number of patients vomiting was 12/20 (60%), 10/20 (50%) and 1/20 (5%) within the first 2 h post-operation in groups 1, 2 and 3, respectively ( P > 0.05 for groups 1 and 2; P < 0.01 for groups 2 and 3; P < 0.001 for groups 1 and 3). In group 2, three patients required rescue medication during the first 2 h post operation, but no signiñcant difference was observed between groups 2 and 3 ( P > 0.05). None of the cases in any of the groups needed any rescue medication during post-operative 2 – 4 h. It is concluded that tropisetron is a highly effective anti-emetic drug in the prophylaxis of post-operative vomiting.

Abstract Several studies demonstrated induction of anesthesia with different plasma target-controlled infusion (TCI) of propofol for LMA insertion. However, there has been no study to compare the standard bolus propofol induction with the effective site TCI for LMA insertion. Objective: Compare the efficacy of induction of anesthesia with propofol for LMA insertion between the effective-site TCI, using 6 μg/mL, and the standard bolus propofol dose of 2.5 mg/kg in elective surgical patients. Methods: A randomized, prospective, single-blinded, clinical study was used for this study. Seventy-eight unpremedicated patients, American Society of Anesthesiologists (ASA) physical status I and II undergoing elective surgical procedure were randomly allocated between two groups. Group 1 received the standard bolus propofol dose of 2.5 mg/kg. Group 2 received effective site TCI (Schnider model) dose of 6 μg/mL for LMA insertion. The hemodynamics and anesthetic depth (Bispectral index score) were monitored and recorded during and immediately after LMA insertion. The number of insertion attempted, insertion quality score, induction time, and propofol doses used were recorded and compared between groups. Results: The success rate of first insertion attempt was equal in both groups (92.3%). There was no significant hemodynamic response difference between the groups during pre-induction, induction, insertion, and post insertion period. The BIS score was significantly lower during post insertion period in group 1 (51.4+11.0) than group 2 (58.4+3.2) (p=0.013). The propofol doses in group 2 were significantly lower than in group 1 (110.6+14.8 vs. 153.5+21.5) (p <0.001). Patients in group 2 required significantly more induction time than group 1 (146.9+42.3 vs. 103.4+33.6 (p <0.001). Conclusion: Propofol induction with TCI provided equal success rate as compared with standard bolus propofol induction for LMA insertion and insertion quality score. TCI significantly lowered the propofol consumption when compared with the standard 2.5 mg/kg propofol dose.

Introduction Robotic colectomy could reduce morbidity and postoperative recovery over laparoscopic and open procedures. This comparative review evaluates colectomy outcomes based on surgical approach at a single community institution. Methods A retrospective review of all patients who underwent colectomy by a fellowship-trained colon and rectal surgeon at a single institution from 2015 through 2019 was performed, and a cohort developed for each approach (open, laparoscopic, and robotic). 30-day outcomes were evaluated. For dichotomous outcomes, univariate logistic regression models were used to quantify the individual effect of each predictor of interest on the odds of each outcome. Continuous outcomes received a similar approach; however, linear and Poisson regression modeling were used, as appropriate. Results 115 patients were evaluated: 14% (n = 16) open, 44% (n = 51) laparoscopic, and 42% (n = 48) robotic. Among the cohorts, there was no statistically significant difference in operative time, rate of reoperation, readmission, or major complications. Robotic colectomies resulted in the shortest length of stay (LOS) (Kruskal-Wallis P < .0001) and decreased estimated blood loss (EBL) (Kruskal-Wallis P = .0012). Median age was 63 years (interquartile range [IQR] 53-72). 54% (n = 62) were female. Median American Society of Anesthesiologists physical status classification was 3 (IQR 2-3). Median body mass index was 28.67 (IQR 25.03-33.47). A malignant diagnosis was noted on final pathology in 44% (n = 51). Conclusion Among the 3 approaches, there was no statistically significant difference in 30-day morbidity or mortality. There was a statistically significant decreased LOS and EBL for robotic colectomies.

Abstract Introduction Preoperative stress and anxiety in pediatric patients are associated with poor compliance during induction of anesthesia and a higher incidence of postoperative maladaptive behaviors. The aim of our study was to determine which preoperative preparation strategy improves compliance of the child during induction and decreases the incidence and intensity of emergence delirium (ED) in children undergoing ambulatory pediatric surgery. Materials and Methods This prospective observational study included 638 pediatric American Society of Anesthesiologists I–II patients who underwent ambulatory pediatric surgery, grouped into four preoperative preparation groups: NADA (not premedicated), MDZ (premedicated with midazolam), PPIA (parental presence during induction of anesthesia), and PPIA + MDZ. The results were subsequently analyzed in four age subgroups: Group 1 (0–12 months), Group 2 (13–60 months), Group 3 (61–96 months), and Group 4 (> 96 months). Preoperative anxiety (modified Yale Preoperative Anxiety Scale [m-YPAS]), compliance of the child during induction (Induction Compliance Checklist [ICC]), and ED (Pediatric Anesthesia Emergence Delirium scale) were analyzed in each group. Results Eighty-one percent of patients in the PPIA + MDZ preparation group presented a perfect compliance during the induction of anesthesia (ICC = 0), less preoperative anxiety (mean score m-YPAS = 26), less probability of ED (odds ratio: 10, 5 [3–37.5]; p < 0.05), and less ED intensity compared with the NADA group (1.2 vs. 5.8; p = 0.001). Conclusion PPIA associated with midazolam premedication improves compliance during induction and decreases the incidence and intensity of ED.

Abstract Between 1970 and 1996, 333 patients with severe aplastic anemia underwent HLA-matched related marrow transplant after conditioning with cyclophosphamide (CY). Thirty-five percent of patients transplanted between 1970 and 1976 (group 1), 12% of those transplanted between 1977 and 1981 (group 2), and 9% of patients transplanted between 1982 and 1997 (group 3) had graft rejection. Graft rejection occurred later among group 3 patients (median, 180 days) than among those in groups 1 and 2 (medians, 28 and 47 days, respectively; P < .001 group 3 v 2). In group 3, 92% of rejecting patients underwent a second transplant, compared with 78% and 77% in groups 1 and 2, respectively. Group 1 patients received various conditioning regimens before second transplant, whereas most patients of groups 2 and 3 received CY combined with antithymocyte globulin (ATG). Graft-versus-host disease (GVHD) prophylaxis after second transplant consisted of methotrexate (MTX) for all group 1 and 2 patients, whereas group 3 patients received MTX combined with cyclosporine (CSP). Over the three time periods studied, first graft rejection decreased from 35% to 9%, and the proportion of rejecting patients undergoing second transplants increased from 77% to 92%. The 10-year probability of survival after second transplants increased from 5% to 83%. Multivariate analysis showed MTX/CSP GVHD prophylaxis to be a significant factor accounting for the increase in patient survival after second transplant. © 1998 by The American Society of Hematology.

Background: Epidural analgesia as a central nuraxial technique which involves use of local anesthetics injected into the epidural space to produce a reversible loss of sensation and is the one of the most common regional technique used for lover abdominal and lover limb surgeries epidural analgesia provides excellent pain relief for surgical procedures below the umbilicus. This study compared the efficacy of epidural dexmedetomidine and fentanyl in addition to 0.2% ropivacaine for post-operative analgesia in elective abdominal surgeries.Methods: Total of 150 patients American Society of Anesthesiologists (ASA) I and II between 20-60 years, undergoing major abdominal surgery were included in this study. The patients divided in three groups of 50 patients each. First group R (ropivaciain 0.2% 9 ml with 1ml normal saline) second group RF (ropivacain 0.2% 9 ml with fentanyl 1 ml) and third group RD (ropivaciain 0.2% 9 ml with dexmedetomidine 1 μ/kg).Results: There is no significant difference in age, weight, sex, and ASA grade in all three groups.Hypotension was observed in 4 (8%) patients of R group, 2 (4%) in RD group and 4 (8%) in RF group. The shivering was present in 2 (4%) R group and 2 (4%) in RD group. Nausea, vomiting was present in R group 2 (4%) and 2 (4%) in RF group. There was no significant difference between the three groups with respect to hemodynamic parameters like heart rate, systolic and diastolic blood pressure and respiratory rate.Conclusions: Dexmedetomidine is a better adjuvant to ropivacaine through epidural route when compared to fentanyl for providing early onset prolonged post-operative analgesia, sedation and stable hemodynamic parameters in intra-abdominal surgeries.
