This double-blinded, randomized clinical trial was designed to evaluate intraocular pressure (IOP) change in cataract surgery using the combination of propofol and remifentanil or the combination of isoflurane and remifentanil. ⋯ Propofol with remifentanil was more effective than placebo or adding remifentanil to isoflurane in management of IOP in cataract surgery.

This study was performed to evaluate the learning curve and related complications of ultrasound (US) guided central venous catheter (CVC) insertion in infants. ⋯ US-guided percutaneous CVC insertion is a safe and reliable method which can be easily and rapidly learned.

Cesarean section is a major operation that can be the predictor of postoperative pain and discomfort and, therefore, providing the effective postoperative analgesia is an important factor to facilitate sooner movement of the patient, better care of infants. The aim of this study was to determine the preventive effect of ilioinguinal nerve block on pain after cesarean section. ⋯ Control of pain after cesarean as one of the most common factors for abdominal surgery will lead to decrease the staying of the patient in hospital, reduce morbidity and lower use of narcotics and analgesics after surgery.

Although it is accepted that inducing cardioplegia is the gold standard in myocardial protection, there is still no consensus on the exact type of the cardioplegia. There are fewer studies on the type of the cardioplegia in hearts of the children than adults and they are contradictory. The effects of esmolol have been reviewed (a type of ultrashort-acting beta-adrenergic antagonist, i.e., ß-blockers) in conjunction with the cardioplegia due to the effect of the β-blockers in reducing the myocardial ischemia and reperfusion. ⋯ The patients who received cardioplegia along with esmolol had less inotropic requirement after operation, and increase in EF and cardiac output (CO) 1 week after surgery. In addition, it reduced damage to the heart during surgery, and patients may have greater stability in the cardiac conduction system.

The aim of this study was to compare the efficacy intravenous (IV) ondansetron with ketamine plus midazolam for the prevention of shivering during spinal anesthesia (SA). ⋯ Prophylactic use of ondansetron 8 mg IV was comparable to ketamine 0.25 mg/kg IV plus midazolam 37.5 μg/kg IV in preventing shivering during SA.
