A comparison of midazolam with trimeprazine as an oral premedicant for children.

The effect of oral premedication was investigated in a double-blind, randomised trial in 85 children undergoing tonsillectomy and/or adenoidectomy. Orally administered midazolam 0.5 mg.kg-1 given 30 min pre-operatively was compared with trimeprazine 2 mg.kg-1 given 90 min pre-operatively and a placebo preparation. Compliance, sedation and ease of induction were assessed as were the duration and quality of recovery. Following premedication with midazolam none of the patients was anxious, crying or distressed on leaving the ward, compared with 2/28 in the trimeprazine group and 5/28 in the placebo group (p = 0.0007). More patients were calm and quiet on arrival in the anaesthetic room following midazolam than following trimeprazine, with both premedicant agents comparing favourably with placebo. There was no significant difference between the three groups in the time to recovery or the sedation score on discharge to the ward. Midazolam is a safe and effective oral premedicant for children.

Hip pain caused by buttock claudication. Relief of symptoms by transluminal angioplasty.

Two patients with severe hip pain proved to have buttock claudication resulting from isolated stenosis of the hypogastric artery. This diagnosis may be elusive if distal pulses are palpable, directing the clinician's suspicion away from vascular pathology. Diagnosis requires angiography. The patients were successfully treated by transluminal angioplasty. Angioplasty is the initial treatment of choice for these patients because the hypogastric artery is usually readily and safely accessible from either the femoral or axillary artery.

Demonstration of mucosal bridging in Crohn's colitis.

Mucosal bridges, strands of normal appearing mucosa traversing the bowel lumen from one wall to an adjacent wall, can occur in inflammatory bowel disease, usually ulcerative colitis. We report the first radiographically documented case, confirmed by colonoscopy, of multiple mucosal bridges and filiform polyps in a patient with Crohn's colitis.

Therapeutic implications of phlebographic obstruction in chronic venous stasis.

The purpose of this work was to evaluate the functional characteristics of the venous system of patients with chronic obstruction of their deep veins proved by phlebography. Sixty-eight extremities in 34 normal volunteers and 21 extremities in 17 patients with chronic venous stasis and phlebographically demonstrated obstruction of their deep veins (popliteal-superficial femoral in 33.3%, common femoral in 23.8%, iliac in 33.3% and inferior vena cava in 9.5%) were evaluated using mercury in silastic strain gauges on the feet to measure venous volume changes on elevation and exercise. Regurgitant flow, corrected for arterial foot blood flow, was calculated. In the control group, the apparent regurgitation range was 0 to 2.3 ml %/min (mean +/- 2 SD). Sixty-two percent of extremities with obstructed deep veins had significant functional regurgitation. Regurgitation was detected by phlebography in only 14.3% of cases. From these results we conclude that obstruction of the deep venous system by phlebography may or may not signify functional obstruction and, in itself, therefore, does not indicate that bypass surgery is an appropriate method of treatment. Selection for surgical correction requires quantitative determination of insufficiency since higher grades of regurgitation probably contraindicate venous bypass.
