Pre-induction low dose pethidine does not decrease incidence of postoperative shivering in laparoscopic gynecological surgeries.
The incidence of shivering in patients undergoing a laparoscopic procedure is stated to be about 40%. A majority of laparoscopic gynecological procedures are taken up on an outpatient basis. Postoperative shivering may delay hospital discharge and is a common cause of discomfort in patients recovering from anesthesia. ⋯ Prophylactic pre-induction, low-dose pethidine does not have major role in preventing postoperative shivering.

Clonidine as an adjunct to intravenous regional anesthesia: A randomized, double-blind, placebo-controlled dose ranging study.
The addition of clonidine to lidocaine intravenous regional anesthesia (IVRA) has been previously reported to improve postoperative analgesia in patients undergoing upper extremity surgery. Our objective was to perform a dose ranging study in order to determine the optimal dose of clonidine used with lidocaine in IVRA. DESIGN #ENTITYSTARTX00026; ⋯ There was no benefit from any dose of clonidine compared to placebo. There were no clonidine-related side effects seen within the dose range studied. In short duration minor hand surgery, the addition of clonidine to lidocaine-based intravenous regional anesthesia provides no measurable benefit.

Comparison of dexmedetomidine and three different doses of midazolam in preoperative sedation.
This study was conducted to compare the efficacy and effects of dexmedetomidine and midazolam in preoperative sedation. ⋯ Dexmedetomidine was as effective as higher doses of midazolam in sedation. The hemodynamic and respiratory effects were minimal. Although dexmedetomidine caused significant decrease in the blood pressure and heart rate, it probably just normalized increased levels caused by preoperative stress.

Failed nasal intubation after successful flexible bronchoscopy: Guide wire to the rescue.
Flexible fiberoptic bronchoscope-guided awake intubation is the most trusted technique for managing an anticipated difficult airway. Even after successfully negotiating the bronchoscope into the trachea, the possibility remains that the preloaded tracheal tube might prove to be inappropriately large, and may not negotiate the nasal structures. ⋯ We present the anesthetic management of five cases with temporomandibular joint ankylosis where, after successful, though slightly traumatic, bronchoscope insertion into the trachea, the tube could not be threaded in. We avoided a repeat bronchoscopy by making an innovative change in the plan.
