Dexmedetomidine a new drug, which is alpha-two agonist, is recommended by manufacturers as an adjuvant in epidural analgesia and anesthesia. ⋯ We conclude that epidural dexmedetomidine 0.5 µg/kg is a good adjuvant providing early onset of sensory and motor block, adequate sedation and prolonged postoperative analgesia with minimal side-effects.

A sustained and effective oropharyngeal sealing with supraglottic airway (SGA) is required to maintain the ventilation during laparoscopic gynecological surgery in the Trendelenburg position. This study was conducted with I-gel™ and ProSeal LMA™, two prototype SGA devices with a gastric access. ⋯ Both I-gel and PLMA are effective for ventilation in gynecological laparoscopic surgeries. However, PLMA provides better sealing as compared to I-gel.

Intubation is known to cause an exaggerated hemodynamic response in the form of tachycardia, hypertension, and dysrhythmias. In cervical spine instability, intubation has to be performed using cervical immobilization to prevent exacerbation of spinal cord injuries. Application of rigid cervical collar may reduce cervical spine movements, but it hinders tracheal intubation with a standard laryngoscope. The aim of this study was to compare the hemodynamic responses to fiberoptic bronchoscope (FOB) and McCoy laryngoscope in patients undergoing elective surgery under general anesthesia with rigid cervical collar simulating cervical spine immobilization in the situation of cervical trauma. ⋯ We suggest that the flexible FOB is an effective and better method of intubation in a situation like traumatic cervical spine injury and provides stable hemodynamics.

The airway management requires refined skills and technical help when associated with cleft lip and palate. Airtraq has improved our airway management skills and has been successfully used for rescue intubation in difficult pediatric airways. ⋯ The presence of cleft lip or palate did not hamper the insertion of Airtraq. The use of malleable stylet to facilitate the loading of the preformed tube into the guide channel is a simple and efficacious improvisation. Airtraq can be utilized as a primary intubation device in children with orofacial clefts.
