An audit of the use of intravenous ketamine for paediatric dental conscious sedation.

AIM: An audit of the use of intravenous ketamine for the provision of conscious sedation in paediatric dentistry was carried out over a three-year period. AUDIT DESIGN: In the audit, 3,751 children were treated and an evaluation was carried out for safety and effectiveness of the drug and procedure, the quality of sedation and clinical procedures provided. In addition, the occurrence of any adverse effects and parental satisfaction were noted along with recovery. All children were ASA I and II, with an average age of 7.5 years. Children were referred because of management problems and were assessed to be at the high anxious level of four and five on the Venham scale. A weight related 0.25 mg/kg was initially administered with additional increments of 0.25 mg/kg given if required. The average total dose provided was 0.41 mg/kg. RESULTS: The majority of children (76%) accepted all treatment with no problems, with 19% experiencing a small amount of resistance. Although a range of dental treatment was provided, it was mostly exodontias of carious primary dentition. A 27% response was provided assessing satisfaction which was very favourable. No adverse reactions occurred although the most common postoperative experience was nausea. CONCLUSION: This audit demonstrated the safety and effectiveness of using intravenous ketamine for paediatric conscious sedation and implications for training and appropriate service delivery were discussed.

Pericardioplasty.

When so desired, a simple technique can be performed to close the pericardium after a cardiac operation. The only requirement is to think about it during the opening of the pericardium and make the appropriate cuts.

Primary repair of traumatic aortic rupture: a preferred approach.

Eighty patients with traumatic rupture of the thoracic aorta were treated. Seven patients died during the initial resuscitation. Forty-three patients underwent surgical repair using the clamp-and-sew technique; 14 patients had a heparin-bonded shunt placed, and 16 patients were repaired using cardiopulmonary bypass. An interposition Dacron graft was used in only 19 patients (26%). The last 32 consecutive patients underwent primary repair of the ruptured aorta. Overall mortality was 19.2% (14 of 80); 9 of 14 patients (64%) had laparotomies along with the aortic repair, and 13 of 14 patients (92%) had three or more associated major injuries. Paraplegia occurred in four cases (5.6%). Traumatic aortic rupture remains a difficult surgical problem. Primary repair, without graft interposition, is the preferred technique and can be accomplished even when the two aortic ends have retracted several centimeters.

Surgery for thoracoabdominal aortic aneurysms.

From July 1985 to July 1989, Loma Linda University Medical Center evaluated 46 thoracoabdominal aortic aneurysms (TAAAs). Forty patients were taken to surgery--18 (45%) were operated on an emergency basis for reasons including rupture (12 patients, 30%), dissection (5 patients, 12.5%), and severe pain (1 patient). The overall mortality for all operated patients was five (12.5%-17% for emergency surgery versus 9% for elective surgery). Nonfatal complications occurred in 40 per cent of patients (16). The overall incidence of paraplegia was 10 per cent (4/40), emergency patients 17 per cent (3/18) versus elective patients 4.5 per cent (1/22). Careful preoperative evaluation, standardization of operative technique, and good postoperative management have improved the outlook for these patients who otherwise would progress to eventual rupture and death. Because mortality and morbidity are substantially reduced in elective patients, we recommend that all patients with TAAAs be evaluated for surgery as soon as diagnosis is made.
