Ketalar (CI-581) in Paediatric Dentistry: A Field Trial in Three Arctic Communities

Three hundred and ten children were anaesthetized with Ketalar for dental surgery in three Arctic communities; in five, conservative dentistry was also carried out. In all cases Ketalar provided satisfactory conditions for the dental work required. The average duration of the surgical procedure was under ten minutes, and five to six children could be treated within an hour. On the average, four teeth were extracted per patient. The retention of protective reflexes, the excellent maintenance of the airway, respiration, and circulation provided a complication-free period of surgery. Only two minor airway problems were encountered, easily manageable with manual support of the jaw and oropharyngeal suction.

Postoperatively the children responded to commands about fifteen minutes following the injection, and were able to sit up unaided after 29 minutes. They were discharged from the recovery room, able to care for themselves, 90 minutes on the average after the injection of a single dose. Most children were quiet during recovery and required little attention; marked restlessness was encountered in 4 per cent, and 14 per cent cried excessively. A state of delirium was observed in twelve children and this was usually of an amusing nature. Nearly 5 per cent complained of headache; double vision was frequently observed. Forty-one per cent of the children vomited at least once and 8 per cent more than three times; vomiting always occurred after the children were conscious and responsive; older children seemed to be more prone to emesis. The incidence of vomiting was some-what reduced when scopolamine 0.1 mg was given intravenously with the induction of anaesthesia.

In this series, Ketalar proved to be a satisfactory and efficient anaesthetic agent for dental surgery, superior to conventionally used anaesthetic techniques. It appeared to be safe without the usual preoperative preparations and premedication, although it should only be administered by a competent anaesthetist.
