ABSTRACT
In 102 cases of severe hypertension (DBP > or = 115 mm Hg), with or without acute complications, efficacy and safety of SL Nifedipine 10 mg (NIF), SL Captopril 25 mg (CAP), IV Metoprolol 15 mg (MET) and SL NIF + IV MET were studied in an inpatient trial. Maximum mean percent reduction in SBP was 13.3, 9.7, 15.7 and 19.9 and in DBP was 21.2, 13.9, 12.5 and 20.4 with NIF, CAP, MET and NIF + MET respectively. A safe DBP of < or = 110 mm Hg (Kaplan) was achieved in 90, 61, 72.2 and 95.2 percent of patients. A statistically significant fall in DBP was observed at 5 minutes with all regimens except CAP which was at 15 minutes. Mild side effects observed were palpitations and flushing (NIF n = 4), taste disturbances (CAP n = 3), heaviness of head (CAP n = 1) and giddiness (MET n = 2, NIF + MET n = 2). The trial data suggest that hypertensive crisis can be managed, without intensive care facility, with all four regimens; this implies significant cost containment.

Fifty two patients of severe hypertension, diastolic blood pressure > or = 115 mmHg, with or without acute complications, were treated with sublingual nifedipine 10 mg or sublingual captopril 25 mg in a randomized prospective in patient study with careful clinical monitoring. Both the drugs were safe and effective in rapidly lowering blood pressure. Nifedipine appeared to be superior to captopril with earlier onset of action, greater magnitude of response and longer duration of action. No significant side effects were observed in either of the two groups.

Eighty-two patients were hospitalized following an accidental exposure to chlorine. All patients presented with dyspnoea and cough. The other symptoms included irritation of throat (53.6%), irritation of eyes (42.3%), headache (29.2%), abdominal pain (26.8%), vomiting (24.3%) and giddiness (9.7%). All of them had bronchospasm and 5 (6%) had cyanosis at the onset. An x-ray of the chest revealed patchy infiltrates in 3 (3.85%) and hilar congestion in 2 (2.44%). Pulmonary function tests showed an obstructive pattern in 27.4%, restrictive in 3.25% and mixed in 53.2%. Pulmonary functions were normal in 16.1% of the patients. Bronchoscopy revealed tracheobronchial mucosal congestion in all cases, hemorrhagic spots in 35.7%, erosions and ulcers in 12.5%. All patients were treated with oxygen, aminophylline, hydrocortisone and antibiotics. Haematemesis (n = 1) and pulmonary oedema (n = 2) developed 12 hours after the admission. Two other patients developed pneumonia 48 hours later. All patients recovered satisfactorily. On follow-up 16 patients had no sequelae after one year. Pulmonary functions were normal in 5 patients after 3 years of follow-up.
