Case ReportsDeath after re-exposure to propofol in a 3-year-old child: a case report.
This case report discusses the cause of death in a 3-year-old child who survived a high dose (20 mg x kg-1 x h-1) of propofol, infused over a period of 15 h, following which the patient developed a combined respiratory and metabolic acidosis, the oxygenation remaining normal. Bronchospasm was assumed to be the cause of hypercapnia. At this time the doctors in charge did not think of a possible side-effect of propofol. ⋯ Although pharmacokinetic studies have pointed to a possible accumulation of propofol during continuous infusions, an interruption of an infusion for several hours has been considered sufficient for practically total clearance of the drug from the body. In this case re-exposure with a recommended dose of propofol was accompanied by bradycardia and dysrythmias that proved to be resistant to therapy and led to fatal cardiac insufficiency with a functioning artificial pacemaker in place. This case raises concerns about the safety of long-term infusions of propofol for sedation in children and possibly also in adults.

Depth of consciousness and deep sedation attained in children as administered by nonanaesthesiologists in a children's hospital.
Sedation of children is administered by nonanaesthesiologists in a variety of locations within our children's hospital. The purpose of this study was to assess the depth of sedation administered to children in four locations using the Bispectral Index (BIS) and the University of Michigan Sedation Scale (UMSS). ⋯ Our data demonstrate wide variations in depth of sedation attained in the hospital. The goal of either conscious or deep sedation was not achieved in a significant number of children. This is a therapeutic failure that requires reassessment of sedation protocols and investigation of new approaches.

Case ReportsAnaesthetic experiences in three sets of conjoined twins in King Chulalongkorn Memorial Hospital.
We describe the anaesthetic management for magnetic resonance image scanning, angiography and surgical operations in three sets of conjoined twins (ischiopagus, throracopagus and pygopagus) in King Chulalongkorn Memorial Hospital during 1996-2002. The anaesthetic technique and associated problems are summarized.

Case ReportsAnaesthetic management in a neonate with congenital complete heart block.
We present the case of a neonate undergoing surgery on the first day of life for the installation of a permanent pacemaker because of the existence of congenital complete heart block (CCHB) with a basal heart rate of 43 b.min(-1) and minimal elevation after initiating an isoproterenol perfusion. The intervention was under general anaesthesia with laryngeal mask airway (LMA) and spontaneous ventilation. The principal anaesthetic goals were to assure adequate anaesthesia, with haemodynamic and respiratory stability, to maintain the best possible heart rate and to avoid postoperative respiratory depression or apnoea.
