Airway obstruction following carotid endarterectomy.

Upper airway obstruction after carotid endarterectomy is a rare but potentially fatal complication of carotid endarterectomy. Upper airway obstruction is also a well recognized complication after neck surgery involving the thyroid gland and cervical spine. The airway obstruction usually develops slowly over a few hours and the onset is unpredictable. We report a patient who developed upper airway obstruction 16 hours following carotid endarterectomy. She required re-intubation in the intensive care unit (ICU). Fibreoptic assessment demonstrated severe supraglottic and glottic oedema. Tracheostomy was performed on day 2 postoperatively. Serial fibreoptic assessment of the upper airway showed gradual resolution of glottic edema and decanulation was successful on day 43.

Acupuncture for frozen shoulder.

This randomised controlled trial was undertaken to evaluate the effectiveness of acupuncture as a treatment for frozen shoulder. Thirty-five patients with a diagnosis of frozen shoulder were randomly allocated to an exercise group or an exercise plus acupuncture group and treated for a period of 6 weeks. Functional mobility, power, and pain were assessed by a blinded assessor using the Constant Shoulder Assessment, at baseline, 6 weeks and 20 weeks. Analysis was based on the intention-to-treat principle. Compared with the exercise group, the exercise plus acupuncture group experienced significantly greater improvement with treatment. Improvements in scores by 39.8% (standard deviation, 27.1) and 76.4% (55.0) were seen for the exercise and the exercise plus acupuncture groups, respectively at 6 weeks (P=0.048), and were sustained at the 20-week re-assessment (40.3% [26.7] and 77.2% [54.0], respectively; P=0.025). We conclude that the combination of acupuncture with shoulder exercise may offer effective treatment for frozen shoulder.

Critical care in obstetrical patients: an eight-year review.

OBJECTIVE: To review the clinical characteristics and outcomes of critically ill obstetrical patients and to determine the outcome predictability using the Acute Physiology and Chronic Health Evaluation (APACHE) II scoring system. METHODS: A retrospective data collection of all obstetrical patients (n = 49) admitted for more than 24 hours to the Intensive Care Unit at Kwong Wah Hospital from 1988 to 1995 was conducted. Demographics, obstetric data, preexistent medical problems, diagnosis, days staying in the ICU and ICU related data were recorded for each patient. RESULTS: Obstetric admissions to ICU during the study period represented 0.12% of all deliveries during this period. There was a predominance of postpartum admissions and obstetric diagnosis responsible for the patients' critical illness. Massive postpartum haemorrhage was the single most common cause of ICU admission, representing 53.0% of all patients. Preeclampsia and eclampsia (14.3%), anaesthesia related complications (14.3%), and medical diseases complicating pregnancy (14.3%) were the other common disease categories for ICU admission. Two cases (4.1%) of surgical disease complicating pregnancy were admitted. The maternal mortality rate was 5.1 deaths per 100,000 total births, or 2 maternal deaths in 39,354 total deliveries in this study period. All deaths were due to nonobstetric causes. The perinatal mortality rate was 10.0% (5 cases) in this study group. CONCLUSIONS: When applying the Acute Physiology and Chronic Health Evaluation (APACHE) II scoring system in predicting the final outcome in this group of obstetric patients, we found that our obstetric patients requiring intensive care had a better outcome than predicted, as expressed by a low mortality ratio (0.25).

Acute myocardial infarction after selective portal-systemic shunt.

A case of myocardial infarction following a distal splenorenal shunt, a selective portal-systemic shunt, in a cirrhotic patient is reported. The post-operative cardiac morbidity was probably related to the hyperdynamic cardiovascular state associated with liver cirrhosis and the increase in intramyocardial tension upon formation of the distal splenorenal shunt.

Management of tetanus: a review of 18 cases.

Eighteen patients with generalized tetanus seen during an 8-year period in three regional hospitals in Hong Kong are reviewed. Eighty-nine per cent of the patients were intravenous heroin addicts who developed a severe type of generalized tetanus with autonomic dysfunction. Pain or stiffness of the neck or back was the commonest presenting symptom, followed by trismus and dysphagia. Most of the patients developed muscle spasms within 24 h of the onset of presenting symptoms. Early ventilatory support and tracheostomy, together with intensive nursing care, were the mainstay of the treatment. Pulmonary and gastrointestinal complications were common during the course of illness and treatment of autonomic dysfunction was often unsatisfactory. The case fatality rate was 25% among the heroin addicts, but full recovery was the usual outcome for those who survived. The simultaneous administration of intrathecal tetanus immunoglobulin tends to reduce mortality.
