To describe the management of a looped and knotted epidural catheter after analgesia for labour and delivery. ⋯ A knot can be a rare cause of a trapped epidural catheter. A suggested approach to the trapped lumbar epidural catheter: 1) Gentle traction on the catheter with the patient in various positions and in various degrees of lumbar flexion. 2) Test for catheter patency by injecting sterile, preservative-free, normal saline through the catheter. 3) Radiological imaging to determine if a knot is present and to determine its location, using radiopaque contrast for patent catheters or a guidewire for occluded catheters. 4) The approach to definitive management is based on the position of the knot. This can range from excision under local anesthetic to consultation with a surgical specialty for more invasive retrieval.

Randomized Controlled Trial Comparative Study Clinical Trial
Patient-controlled intranasal analgesia: effective alternative to intravenous PCA for postoperative pain relief.
To investigate whether the nasal route for fentanyl administration in patient-controlled analgesia (PCA) provides as effective postoperative analgesia as intravenous PCA. ⋯ Intranasal PCA with fentanyl was an effective alternative to i.v. PCA in postoperative patients.

Randomized Controlled Trial Clinical Trial
Peroperative titration of morphine improves immediate postoperative analgesia after total hip arthroplasty.
To determine the Influence of peroperative titrated morphine on postoperative pain control. ⋯ This study demonstrated that the peroperative administration of morphine can facilitate immediate postoperative pain management.

Randomized Controlled Trial Clinical Trial
Acupressure wristbands do not prevent postoperative nausea and vomiting after urological endoscopic surgery.
To evaluate the efficacy of acupressure wristbands in the prevention of postoperative nausea and vomiting (PONV). ⋯ Application of acupressure wristbands at the P6 of both forearms 30 min before induction of anesthesia did not decrease the incidence of PONV in patients undergoing endoscopic urological procedures.

Comparative Study Clinical Trial
Smoking does not alter the dose-requirements and the pharmacodynamics of rocuronium.
Controversial data about the effect of smoking on the dose-requirements and the pharamcodynamics of rocuronium have been reported recently. This study was conducted to evaluate the dose-requirements and the pharmacodynamics of rocuronium in smokers using target controlled infusion. ⋯ Smoking does not alter the dose-requirements for rocuronium and no effects on the onset time, degree of block, time to maximum block, duration 10% and spontaneous recovery index were observed.
