Pretreatment with 800mg and 1200mg gabapentin 2h before the operation increased the level of sedation and reduced the incidence and severity of myoclonic movements due to etomidate.

In clinical practise we believe that after 1mgkg(-1) loading dose, 150μgkg(-1)min(-1) iv esmolol dose is sufficient to suppress responses to tracheal intubation without increasing side effects.

Our case report indicates that although syndrome of inappropriate antidiuretic hormone secretion and autonomic dysfunction are rarely the initial characteristics of Guillain-Barré syndrome, the possibility of postoperative syndrome of inappropriate antidiuretic hormone secretion should be kept in mind. The presence of secondary hyponatremia in this type of clinical presentation may delay diagnosis.

Objectives:To compare midazolam and propofol sedation in hypoalbuminemic geriatric patients under spinal anesthesia in hip surgery with bispectral index monitoring.Methods:This prospective and randomized study was completed in the Department of Anesthesiology, Okmeydani Training and Research Hospital, Istanbul, Turkey between February 2013 and December 2014. Sixty patients undergoing elective hip surgery under spinal anesthesia in the geriatric age group with albumin levels below 3 g/dl were randomly divided into Group I and Group II. After administration of spinal block, Group I were given 0.05 mg/kg bolus midazolam, and then 0.02-0.1 mg/kg/hr dose infusion was begun. In Group II, 1 mg/kg bolus propofol was given within 10 minutes, and then 1-3 mg/kg/hr infusion was begun. The systolic arterial pressure, diastolic arterial pressure, mean arterial pressure, heart rate, peripheral oxygen saturation values, respiratory rate, and Wilson’s 5-stage sedation score were recorded at 15-minute intervals. At the end of the operation, the recovery time and surgeon satisfaction were recorded.Results:The recovery times for patients in Group I were found to be longer than in Group II (p<0.05). The respiration rate in patients in Group I at the start of surgery, 15th minute of surgery, and after surgery were lower than in Group II (p<0.05).Conclusion:We conclude that propofol is more reliable in terms of hemodynamic stability than midazolam, as it causes less respiratory depression and faster recovery in the propofol group.
