Pain after open inguinal hernia surgery can be moderate to severe and is known to prolong hospital stay and delay return to normal daily activities. ⋯ The duration of analgesia provided by 0.25% bupivacaine was significantly longer than that provided by 0.125% bupivacaine through US-guided TAP block in inguinal hernia repair.

The use of succinylcholine for rapid sequence induction in patients with open globe injuries may be detrimental to the eye. ⋯ MgSO4 30 mg/kg as well as 50 mg/kg effectively prevented the rise in IOP, MAP, and HR associated with rapid sequence induction by succinylcholine and endotracheal intubation.

Positive end-expiratory pressure (PEEP) at the time of induction increases oxygenation by preventing lung atelectasis. However, PEEP may not prove beneficial in all cases. Factors affecting the action of PEEP have not been elucidated well and remain controversial. Pulmonary vasculature has direct bearing on the action of PEEP as has been proven in the previous studies. Thus, this prospective study was planned to evaluate the action of PEEP on the basis of pulmonary artery systolic pressure (PASP) which is noninvasive and easily measured by transthoracic echocardiography. ⋯ Morbidly obese patients who have PASP >30 mm Hg benefit most from the PEEP. Thus, PASP which is an easily measurable noninvasive parameter can be used as a criterion for selecting patients who benefit from PEEP application.

Many adjuvants have been used with local anesthetics to reduce the time of onset and prolong the duration of analgesia in brachial plexus blocks. However, few studies are there using verapamil as an adjuvant with levobupivacaine. ⋯ The addition of verapamil as an adjuvant to levobupivacaine in brachial plexus blockade delayed the requirement of rescue analgesia with decreased onset time and prolonged duration of sensory and motor block characteristics.
