Back pain is one of the most common disorders seen in general practice. Patients with chronic low back pain form a large proportion of the work of any pain relief unit. The aetiology of low back pain and the post-laminectomy pain syndrome are briefly presented and treatment of the 'failed back surgery patient' and the patient with arachnoiditis are discussed.
Arterial blood pressure and pulse rate changes following tracheal intubation were studied in 80 patients undergoing oral surgical procedures who received an etomidate/suxamethonium anesthetic induction sequence. Three treatment groups and a control group were used. Intravenous labetalol (1 mg/kg), acebutolol (0.25 mg/kg), lidocaine (2 mg/kg), and saline (1 ml), injected prior to anesthesia, were compared with respect to their effect on the hemodynamic consequences of direct laryngoscopy followed by the passage of an endotracheal tube. A pre-induction dose of labetalol was found to be more effective than acebutolol and lidocaine in attenuating the pressor response to instrumentation and intubation. Labetalol should prove most useful for those patients at risk from the transient hypertension and tachycardia following instrumentation and intubation.
A new protamine sulphate titration kit has been developed and tested in patients undergoing cardiac bypass surgery. When a prototype of the kit was used, protamine sulphate dosage was significantly reduced (P less than 0.01) without a significant increase in 24-hour postoperative blood loss (P greater than 0.05).

Epidural fentanyl (Sublimaze; Janssen) in the management of postoperative pain, with particular attention to efficacy and safety, was investigated. A treatment group (group 1) of 31 patients and a control group (group 2) of 30 patients were used. Group 1 received epidural fentanyl 100 micrograms postoperatively, while in the control group pain was treated with intramuscular pethidine 1.5 mg/kg 4-6-hourly as required during the 11 hours in the recovery room. Epidural fentanyl started working within 20 minutes and provided excellent analgesia for 8 hours or more postoperatively, comparable to repeated doses of intramuscular pethidine. Of the patients in group 1 13% experienced tolerable pruritus and the incidence of nausea and vomiting was small relative to that recorded in group 2.

Allergic reactions to the intravenous drugs used in anaesthesia pose a major problem for the anaesthetist, since they represent an unpredictable and occasionally life-threatening event. Reports of 2 such cases are presented, and the incidence, assessment and prophylaxis of such reactions are discussed.
An 18-year-old girl was admitted to hospital after deliberately ingesting about 90 capsules of mefenamic acid 250 mg (Ponstan). The management is discussed.
A 44-year-old white woman with Charcot-Marie-Tooth disease underwent an abdominal hysterectomy. The pre-operative preparation and anaesthetic management are presented, and the specific problems discussed.
Patients with the more common connective tissue disorders require surgical operations more frequently than has been realized. They may present the anaesthetist with many potential problems. A few minutes of careful questioning and examination pre-operatively may prevent a tragic situation. A history of drug therapy is essential pre-operative information, particularly since many of these patients will need augmentation or coverage with steroid drugs. The anaesthetist must be aware of the patient's general state of health and must search for evidence of pulmonary, cardiac or haematological abnormalities.
An 18-year-old black youth with myositis ossificans progressiva recently underwent eye surgery. The clinical, laboratory and radiological findings are described. The problems associated with anaesthesia are presented and their management is discussed. The condition is briefly reviewed.
A 14-year-old White boy was recently admitted to the Universitas Hospital, Bloemfontein, with an adrenergic/antimuscarinic syndrome following drug overdose. The causation of the syndrome and successful management with physostigmine salicylate are discussed.
A 30-year-old woman who was 28 weeks pregnant was admitted to hospital after deliberate ingestion of 300 ml Dettol. The patient's management and that of Dettol overdose are discussed.

The effect of premedication with intramuscular atropine and glycopyrrolate on the cardiovascular changes resulting from the performance of laryngoscopy and tracheal intubation has been evaluated in two groups of 25 patients undergoing surgery. Neither atropine nor glycopyrrolate attenuated the hypertensive and tachycardic response to laryngoscopy and intubation; both significantly enhanced it (P less than 0,05).
