Randomized Controlled Trial Clinical Trial
Low dose intrathecal ropivacaine with or without sufentanil provides effective analgesia and does not impair motor strength during labour: a pilot study.
Although ropivacaine has been used to provide spinal anesthesia in the surgical population, its intrathecal administration for labour analgesia has only recently been described. We evaluated the effects of low dose intrathecal ropivacaine with or without sufentanil for labour analgesia. ⋯ Low dose ropivacaine provides effective analgesia during labour via the intrathecal route. It can be mixed with sufentanil in the above-mentioned concentrations to improve both the quality and duration of analgesia. Fetal outcome remains favourable. It may provide minimal or no motor block, to facilitate ambulation.

Randomized Controlled Trial Clinical Trial
Preoperative diclofenac is a useful adjunct to spinal anesthesia for day-case varicose vein repair.
To examine if preoperative diclofenac 50 mg or diazepam 10 mg po are useful adjuncts to spinal anesthesia for day-case varicose vein repair. ⋯ Diclofenac premedication reduced the analgesic requirements during the first eight hours after varicose vein repair.

Case Reports
Loss of the airway during tracheostomy: rescue oxygenation and re-establishment of the airway.
To describe loss of the airway during tracheostomy and suggest a method for re-establishment of the airway and providing rescue oxygenation. ⋯ To restore a lost airway during tracheostomy, we recommend that a jet ventilation airway exchange catheter (JVAE) be inserted in the endotracheal tube through a bronchoscope port attachment prior to surgical entry into the trachea. The JVAE will also ensure continued ability to oxygenate the patient.

Evaluate oxygen jet ventilation in a patient with tracheal stenosis undergoing stent insertion. ⋯ Low frequency jet ventilation in a patient with tracheal stenosis provided adequate ventilation as well as a non- obstructed field during fibreoptic bronchoscopy and stent insertion.

Case Reports
Combined spinal-epidural anesthesia for Cesarean section in a patient with peripartum dilated cardiomyopathy.
To report a case of peripartum dilated cardiomyopathy associated with morbid obesity and possible difficult airway presenting for elective Cesarean section, which was successfully managed with combined spinal-epidural anesthesia. ⋯ In patients suffering from peripartum cardiomyopathy, undergoing Cesarean section, combined spinal-epidural anesthesia may be an acceptable anesthetic alternative.
