Awake fiberoptic intubation (AFOI) is a recommended technique for anticipated difficult airway. An ideal regime should provide patient comfort, cooperation, amnesia, hemodynamic stability, and blunt airway reflexes and maintain a patent airway with spontaneous ventilation. The aim of our study was to compare intubation conditions between dexmedetomidine and fentanyl-midazolam combination during AFOI. ⋯ Dexmedetomidine is more effective than midazolam-fentanyl during AFOI, as it provides better intubation condition, hemodynamic stability, and preservation of airway and spontaneous ventilation.

Postoperative pain after breast cancer surgery is unavoidable. Thoracic paravertebral block (TPVB), a locoregional anesthetic technique, has been proven successful for postoperative pain management in different thoracic surgical procedures, such as thoracotomy, breast cancer surgeries. Clonidine, an adjuvant, in TPVB may enhance the quality and prolong the duration of analgesia. This prospective study was to evaluate the effectiveness of clonidine; administered with TPVB; in addition to conventional local anesthetic solution. ⋯ Clonidine as adjuvant in TPVB provided profound analgesia for up to 48 h postoperatively for patients undergoing breast cancer surgery without any appreciable side effects.

The Proseal LMA(PLMA), which has been designed especially for positive pressure ventilation and protection against aspiration can act as an alternative to Endotracheal Tube (ETT) as an effective airway device for patients undergoing elective Laparoscopic surgeries. ⋯ A properly positioned PLMA is a suitable and safe alternative to ETT for airway management in adequately fasted, adult patients undergoing elective Laparoscopic surgeries.

Transsphenoidal approach to pituitary tumors is a commonly performed procedure with the advantage of a rapid midline access to the sella with minimal complications. It may be associated with wide fluctuations in hemodynamic parameters due to intense noxious stimulus at various stages of the surgery. As duration of the surgery is short and the patients have nasal packs, it is prudent to use an anesthestic technique with an early predictable recovery. ⋯ A continuous intravenous infusion of dexmedetomidine as compared to oral clonidine improved hemodynamic stability in patients undergoing transnasal transsphenoidal resection of pituitary tumors.
