Randomized Controlled TrialEffects of the addition of low-dose ketamine to propofol-fentanyl anaesthesia during diagnostic gynaecological laparoscopy.
Diagnostic gynaecological laparoscopy (DGL) is a brief procedure, generally performed on an outpatient basis. Propofol-fentanyl is often used for anaesthesia in minor outpatient procedures because of its rapid onset, short duration of action and smooth patient awakening. However, propofol has various cardiovascular effects such as reduced arterial pressure, cardiac output and cardiac index. Ketamine is an intravenous anaesthetic and short-acting analgesic that could alleviate the haemodynamic effects of propofol due to its sympathomimetic activity. The aim of this placebo-controlled trial was to evaluate the effects of the addition of low-dose ketamine to propofol-fentanyl anaesthesia in DGL. ⋯ Use of low-dose ketamine with propofol-fentanyl anaesthesia in patients undergoing DGL was associated with less pain during propofol injection, lower incidence of haemodynamic changes, lower total dose of propofol and improved postoperative analgesia.
