Comparative analysis of the effect of various types of combined anaesthesia on the central hemodynamics in laparoscopic cholecystectomy

Abstract

Introduction. At present, laparoscopic cholecystectomy is a type of minimally invasive intervention, mostly performed for the treatment of patients with cholelithiasis. A large number of procedures worldwide taken into consideration, the issue of the effect of various anaesthesia types on the central hemodynamics becomes increasingly important, since its state often determines possible complications of surgical intervention. Aim. Objective is to assess the effect of various combined anaesthesia types on the central hemodynamics in laparoscopic cholecystectomy. Material and methods. Examination included 119 patients (aged between 20 and 82) who had undergone surgery for acute cholecystitis. Laparoscopic cholecystectomy with the use of carboxy peritoneum (CP) was performed in all cases. Depending on the type of anaesthesia, patients were divided into 3 groups: Group 1 (n = 44) – those who were operated on under combined general intravenous anaesthesia (CGIA); Group 2 (n = 44) – the surgery was performed under combined inhalation anaesthesia (CIA) with sevoflurane; Group 3 (n = 31) – laparoscopic cholecystectomy was performed under combined spinal anaesthesia (CSA) with 0.5% bupivacaine. Subject to comparison were the indices of hemodynamic profile and intra-operative analgesia that was judged on the amount of narcotic analgesics used. The research was authorized by the Bio-ethical Commission of Kyiv City Hospital ? 4. Permission number is U22072016. All patients gave prior written permission to participate in this study. Results. Average systolic arterial pressure in the groups with carbon dioxide insufflated into abdominal cavity: Group 1 – 137.5 ± 18.9 mm Hg; Group 2 – 136.6 ± 17.7 mm Hg; Group 3 – 115.0 ± 13.7 mm Hg. In Group 3, systolic arterial pressure values differed statistically from those in groups 1 and 2 (p < 0.001). Average systolic arterial pressure under carboxy peritoneum: Group 1 – 101.7 ± 14.1 mm Hg; Group 2 – 100.0 ± 12.2 mm Hg; Group 3 – 86.7 ± 10.4 mm Hg. Average doses of fentanyl used for anaesthesia in the groups were: Group 1 – 11.7 mcg/kg; Group 2 – 10.9 mcg/kg; Group 3 – 6.28 mcg/kg. Conclusions. The changes of central hemodynamics in the patients who had undergone combined spinal anaesthesia for laparoscopic cholecystectomy were found to be the least as compared with combined prevenous and endotracheal anaesthesia.
