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.

Clinical TrialLight-guided intubation via the intubating laryngeal mask using a prototype illuminated flexible catheter. Clinical experience in 400 patients.
The transillumination of the soft tissues of the neck using lighted stylets has been used as an aid for tracheal intubation. We evaluated the efficacy and safety of a prototype illuminated flexible catheter to facilitate light-guided intubation through the intubating laryngeal mask. ⋯ We conclude that the use of the illuminated flexible catheter facilitates the intubation through the intubating laryngeal mask. The suggested light-guided intubating method proved to be a simple, safe and effective technique.

Case ReportsUse of an EEG-bispectral closed-loop delivery system for administering propofol.
Closed-loop control of propofol delivery was instituted in three patients who received a propofol infusion as part of: (Case 1) general "balanced" anesthesia, (Case 2) total intravenous anesthesia, and (Case 3) monitored anesthesia care. The bispectral index was the input variable used in a proportioned, integral and differential controller to determine the infusion rate of propofol required to maintain a stable level of hypnosis (Cases 1 and 2) or sedation (Case 3). This feedback control system provided intraoperative hemodynamic stability and a prompt recovery from the sedative-hypnotic effects of propofol.

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 TrialCutaneous sympathetic vasoconstrictor reflexes for the evaluation of interscalene brachial plexus block.
Although signs of sympathetic blockade following interscalene brachial plexus block include Horner's syndrome, increased skin temperature and vasodilatation, the degree of sympathetic blockade is not easily determined. The aim of this study was, therefore, to use activation of cutaneous finger pad vasoconstrictor reflexes for description and quantification of the degree of sympathetic blockade following unilateral interscalene brachial plexus block. ⋯ Interscalene brachial plexus block reduces regional sympathetic nervous activity, illustrated by increases in skin blood flow, skin temperature and attenuated vasoconstrictor responses to an inspiratory gasp. The inspiratory gasp vasoconstrictive response is a powerful and sensitive indicator for monitoring the sympathetic blockade following interscalene brachial plexus block.
