Randomized Controlled Trial Comparative Study Clinical TrialPatient evaluation and comparison of the recovery profile between propofol and thiopentone as induction agents in day surgery.
The patient's subjective perception of the quality of his/her recovery after day case anaesthesia with propofol or thiopentone as induction agents is still controversial. The authors investigated the perception and quality of awakening after anaesthesia during the recovery period and at 24 hours and 72 hours, in outpatients undergoing anaesthesia induced either with propofol or thiopentone and maintained with a volatile anaesthetic. In a double-blind study in adults undergoing knee arthroscopy in a day surgery unit, propofol and thiopentone were compared as induction agents in 60 randomized outpatients. ⋯ In the propofol group, patients awoke more rapidly (9.2 +/- 5.8 vs 12.3 +/- 5.8 min) (P < 0.05); however, the CFFT measurements did not show any significant difference between the groups, except at time = 0 min, when 17 patients in the propofol group were able to perform the test versus only 10 patients in the thiopentone group (P < 0.05). At 4, 24, and 72 hours postoperatively, the authors were unable to detect any difference between the two groups. Except for early recovery, there were no differences between the intermediate and late recovery profiles, when propofol or thiopentone was used as the anaesthetic induction agent in day surgery.

Randomized Controlled Trial Clinical TrialSubcutaneous tunnelling of epidural catheters for postoperative analgesia to prevent accidental dislodgement: a randomized controlled trial.
The use of subcutaneous tunnelling to prevent movement of epidural catheters was examined in a prospective controlled trial. There were 113 patients in the standard group and 100 in the tunnelled group. The groups were similar with respect to age, sex and weight. ⋯ In total, 60 catheters moved significantly from their initial position: 17 (28%) moved inwards and 43 (72%) moved outwards. 159 catheters were still functioning at the time of their removal, 76 standard and 83 tunnelled. This represents 67 and 83% of the two groups respectively. Subcutaneous tunnelling was shown to prevent clinically significant inwards (P = 0.043) and outwards (P = 0.0005) movement of epidural catheters and is more likely to result in a functional epidural blockade at the time of catheter removal (P = 0.0084).
