Epidural catheter misplaced into the thoracic cavity: Utilized to provide interpleural analgesia.
Thoracic epidural analgesia is one of the most effective and time-tested modalities of providing postthoracotomy pain relief. It improves postoperative pulmonary outcome. Nevertheless, being a blind procedure several complications have been associated with the technique. ⋯ We have discussed a patient who underwent a right thoracotomy for excision of emphysematous bulla of lung under general anesthesia with thoracic epidural. The epidural catheter was misplaced in the pleural cavity and was detected intraoperatively after thoracotomy. The catheter was left in situ and was successfully utilized to provide postoperative analgesia via the interpleural route.

Laryngoscopy and intubation cause an intense reflex increase in heart rate, blood pressure, due to an increased sympathoadrenal pressor response. Lignoocaine has shown blunting of pressor response to intubation. Dexmedetomidine has sympatholytic effects. ⋯ We conclude that dexmedetomidine 1μg/kg adequately attenuates the hemodynamic response to laryngoscopy and endotracheal intubation when compared with dexmedetomidine 0.5μg/kg and lignocaine 1.5mg/kg.

Flupirtine is a centrally-acting, nonopioid analgesic that interacts with N-methyl-D-aspartate receptors. ⋯ Oral flupirtine and diclofenac sodium were equally effective for postoperative analgesia. There was faster onset of analgesia with diclofenac sodium, but flupirtine was better tolerated by the patients because of its minimal adverse effects.

There were several studies using either low dose Bupivacaine as unilateral selective spinal anesthesia (SSA) or low dose lidocaine SSA for ambulatory knee arthroscopy. There were many concerns about high failure rate, complications, and different times to home readiness discharges. ⋯ Both techniques of SSA were clinically efficient as subarachnoid block, and they had less postoperative side effects. Lidocaine spinal was more eligible for fast-tracking anesthesia than bupivacaine spinal with shorter time to ambulate and home-readiness time.

Rocuronium (R) bromide and vecuronium (V) are monoquaternary aminosteroid compounds. The aim of this study was to evaluate the onset time, conditions of intubation and duration of action of equipotent doses (3ED95) of R and V. ⋯ At equipotent doses, R provides clinically acceptable intubation conditions much earlier than V without significant variation in clinical duration of action.
