A 12-year-old girl who had had an operation for a posterolateral diaphragmatic hernia was admitted to the hospital because of enuresis. Physical examination and radiologic studies revealed the spleen behind the urinary bladder, left-sided hydronephrosis, and a high volume of residual urine. The hydronephrosis and residual urine resolved immediately(More)
We assessed the cardiorespiratory effects of laparoscopic procedures in 27 infants aged between 36 and 365 days. Infants were monitored and anaesthetised in a standardised manner. Heart rate, mean arterial pressure, end-tidal carbon dioxide and oxygen saturation were recorded, and blood gases were measured at 5 min after intubation, 15 and 30 min after(More)
BACKGROUND Thoracotomy causes severe pain in the postoperative period. The aim was to evaluate effectiveness of two pain treatment methods with morphine on postthoracotomy pain and stress response. METHODS Thirty-two children undergoing major thoracotomy for noncardiac thoracic surgery were allocated to receive either single dose of thoracic epidural(More)
AIM Caroli's disease is a simple form of intrahepatic bile duct ectasia. It can be complicated with the involvement of liver parenchyma and portal hypertension.

We compared the endocrine and metabolic changes during acute emergency abdominal surgery performed using either laparoscopy or laparotomy in children. Twenty-nine children aged 1.5-14 years were assigned to undergo laparoscopy (n = 15) or laparotomy (n = 14) with a standard anaesthesia technique. Arterial blood gases and blood prolactin, cortisol,(More)
OBJECTIVE To determine the influence of midazolam on the function of the lower urinary tract when used to sedate the patient. PATIENTS AND METHODS Urodynamic studies were performed on 20 patients (seven boys and 13 girls, mean age 4.04 years, range 1 day to 10 years) before and after the intranasal administration of 0.5 mg/kg of midazolam. The patients'(More)
BACKGROUND The use of N2O during low-flow anesthesia (LFA) causes difficulty in predicting inspired gas mixtures and oxygen concentration due to accumulation. An alternative technique, which uses a mixture of oxygen and air and a morphine infusion to replace N2O, has been evaluated in children during LFA, and the clinical effects and composition of gases in(More)
BACKGROUND AND OBJECTIVES Since the first report of epidural opioid administration to pediatric patients, several studies have described the quality of analgesia, doses, pharmacokinetics, and side effects of this procedure. A pediatric series using an easy and cheap single-injection technique of epidural morphine administration for postoperative analgesia(More)
Bleeding from esophageal varices is an important cause of morbidity and mortality in children with portal hypertension. The treatment protocol is planned according to the etiologic factors underlying the portal hypertension, which may be either intrahepatic or extrahepatic. Although portasystemic venous shunt operations were common previously, they are now(More)
