- ItemAnaesthesia and the diabetic patient(HMPG, 1985) Roelofse, J. A.; Erasmus, F. R.Since it is estimated that 1 out of every 2 diabetic patients will require surgery at some point in his lifetime, it is imperative that the anaesthetist should understand the disease process as well as the anaesthetic problems associated with it. This article emphasizes the medical, surgical and anaesthetic aspects of the treatment of patients with diabetes mellitus.
- ItemAnaesthesia for abdominal hysterectomy in Charcot-Marie-Tooth disease : a case report(Health & Medical Publishing Group, 1985) Roelofse, J. A.; Shipton, E. A.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.
- ItemAnaesthesia in connective tissue disorders(Health and Medical Publishing Group -- HMPG, 1985-03) Roelofse, J. A.; Shipton, E. A.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.
- ItemBlood oxygen saturation levels during conscious sedation with midazolam. A report of 16 cases(Health & Medical Publishing Group, 1986) Roelofse, J. A.; Van der Bijl, P.; Joubert, J. J.; Breytenbach, H. S.In a double-blind randomized study on 16 healthy individuals, two groups of subjects (8 in each group) received either midazolam (Dormicum; Roche) 0,1 mg/kg or placebo intravenously for conscious sedation during oral surgical procedures. Oxygen saturation of the blood was measured at different stages. Ten minutes after administration of the drug, the percentage oxygen saturation was significantly lower (P<0.05) in the midazolam group than in the placebo group.
- ItemNarkose vir timektonie in myasthenia gravis(Health & Medical Publishing Group, 1981-10-17) Roelofse, J. A.ENGLISH ABSTRACT: This report emphasizes the medical, surgical and anaesthetic aspects of the treatment in cases of myasthenia gravis. Since many of the drugs used in anaesthesia affect the activity of the neuromuscular conduction mechanism, the anaesthetist should be aware of the pathophysiology of the disease and of the effect which these drugs have on it.
- ItemObstruction of a breathing circuit : a case report(Health & Medical Publishing Group, 1984) Roelofse, J. A.; Shipton, E. A.Preventable mishaps resulting from human error contribute to anaesthetic risk, as demonstrated in the case report presented. The incidence of anaesthetic-associated deaths has fallen steadily since 1935, and general anaesthesia is now a very safe procedure, provided the anaesthetist takes the requisite precautions.
- ItemPlasma cholinesterase levels during cardiopulmonary bypass : a report on 10 cases(Health & Medical Publishing Group, 1987) Roelofse, J. A.; Van der Bijl, P.Plasma cholinesterase levels of 10 male patients were determined before, during and after cardiopulmonary bypass surgery. These levels dropped significantly below the pre-anaesthetic values after commencing anaesthesia. In 6 patients levels returned to pre-anaesthetic values before or on the 2nd post-operative day. This could not be explained in terms of enzymic biosynthesis alone, and it is suggested that postoperative fluid readjustments may play an important role in certain cases.
