Cholecystectomy, Laparoscopic

Publication Title: 
Acta Anaesthesiologica Scandinavica

BACKGROUND: Nitrous oxide (N2O) has been suggested to contribute to bowel distension, resulting in worsened operating conditions for laparoscopic surgery, and to increase incidence of postoperative nausea and vomiting. Therefore, our objective was to assess the feasibility of two remifentanil-based anaesthetic regimens free from N2O with special regard to recovery profile, postoperative analgesic demand and side effects in patients undergoing laparoscopic cholecystectomy.

BACKGROUND: Target-controlled infusions (TCI) are used to simplify administration and increase precision of i.v. drugs during general anaesthesia. However, there is a limited relationship between preset targets and measured concentrations of drugs and between measured concentrations and measures of brain function, such as the bispectral index (BIS). METHODS: We set out to evaluate the performance of TCI devices for propofol (Diprifusor) and remifentanil (Remifusor, prototype), during laparoscopic cholecystectomy in 21 patients.

OBJECTIVE: To present hypnosedation and the feasibility of this technique performed for laparoscopic procedure. STUDY DESIGN: Retrospective and descriptive study of feasibility. PATIENTS AND METHODS: Hypnosis can significantly reduce intraoperative requirements of intravenous sedation for surgery under local anaesthesia. Modifications of surgical procedure: laparoscopic surgery under local anaesthesia and hypnosis is performed using a subcutaneous lifting of anterior abdominal wall. Insufflation is only use to push out smoke.

STUDY OBJECTIVE: The objective of this study was to examine the utility of the transesophageal echo-Doppler device in evaluating hemodynamic changes during laparoscopic cholecystectomy. DESIGN: This was a prospective, controlled, observational open study. SETTING: The study took place in a university hospital. PATIENTS: Twenty patients with ASA physical statuses II and III undergoing laparoscopic cholecystectomy were enrolled into the study. INTERVENTIONS AND MEASUREMENTS: A standardized general anesthetic and surgical technique was used for all patients.

BACKGROUND: The aim of this study was to evaluate the usefulness of spectral frequency index (SFx) monitoring to assess the depth of anaesthesia during propofol-opioid total intravenous anaesthesia (TIVA). METHODS: Thirty-three patients scheduled for laparoscopic cholecystectomy under propofol TIVA were prospectively and randomly allocated to receive either remifentanil (bolus of 1.0 microg/kg, followed by continuous infusion from 0.25 to 0.05 microg/kg/min) [n = 18] or alfentanil (bolus of 10 microg/kg, followed by continuous infusion from 2.0 to 0.5 microg/kg/min) [n = 15].
