Randomized Controlled Trial Clinical TrialEffects of intraperitoneal lidocaine combined with intravenous or intraperitoneal tenoxicam on pain relief and bowel recovery after laparoscopic cholecystectomy.
Previous work has demonstrated that intraperitoneal (i.p.) lidocaine may provide analgesia after laparoscopic cholecystectomy. The aim of this prospective, randomized, double-blind study was to compare pain relief, recovery variables, and side effects after i.p. instillation of lidocaine plus tenoxicam given either i.v. or i.p. after laparoscopic cholecystectomy. ⋯ Combination of intraperitoneal lidocaine and tenoxicam provided better analgesia on movement, and faster return of bowel function compared with i.p. lidocaine and i.v. tenoxicam during the 24 h period after surgery.

Comparative Study Clinical Trial Controlled Clinical TrialA comparison of three doses of sufentanil in combination with bupivacaine-adrenaline in continuous epidural analgesia during labour.
Sufentanil is now frequently added to local anaesthetic in labour epidural analgesia. However, this opioid has some side effects such as pruritus, and in higher doses could harm the neonate. The purpose of this study was to compare three doses of sufentanil combined with low-dose bupivacaine, to determine the lowest appropriate dose. ⋯ We found no difference in the analgesic effect between three different concentrations of sufentanil. We conclude that the lowest dose may be used. This should decrease the risk of adverse effects on mother and child.

Clinical TrialElastic pressure-volume curves indicate derecruitment after a single deep expiration in anaesthetised and muscle-relaxed healthy man.
In acute respiratory distress syndrome, lung volume is lost immediately after positive end-expiratory pressure (PEEP) is removed and is not immediately regained when PEEP is restored to its original value. The aim of this study was to investigate whether the same phenomenon also occurs in cardiopulmonary healthy individuals during anaesthesia and muscle relaxation. ⋯ During anaesthesia and muscle paralysis, the Pel-V relations change immediately when 5 cmH2O of PEEP is removed. This phenomenon is probably mainly caused by closure of small airways and only in a minor part, if any, by formation of atelectasis. This study indicates that under these conditions lung volume might easily be normalised by a large breath producing an airway pressure of 20 cmH2O.

The effect of the obstetrician group and epidural analgesia on the risk for cesarean delivery in nulliparous women.
The effects of regional anesthesia and of the obstetrician on the risk of cesarean delivery remain controversial. The purpose of this study was to determine whether epidural analgesia or the obstetrician group is associated with an increase in the risk for cesarean delivery in nulliparous women. ⋯ The obstetrician group is independently associated with the risk of cesarean delivery in nulliparous women, but we could not demonstrate this association with epidural analgesia. We suggest that in future studies regarding epidural analgesia and cesarean delivery, the obstetrician group should be included as a variable.
