To determine the effect of metoclopramide on gastric emptying in severe head injuries: a prospective, randomized, controlled clinical trial.
To determine the effect of 8-hourly administration of 10 mg intravenous metoclopramide, over a 48-h period on gastric emptying in severe head injury (SHI), 22 patients were prospectively randomized (Glasgow Coma Score of 3-8) to receive 2 ml of intravenous metoclopramide or 2 ml of 5% saline 8-hourly for 48 h. Baseline and serial blood paracetamol absorption assays were performed at time (t) = 0, 15, 30, 45, 60, 90 and 120 min on day 0 and day 2. The area under the curve between the day 0 and day 2 was used to measure the degree of gastric emptying. In SHI, sequential doses of metoclopramide did not appear to improve gastric motility within subject comparisons (p = 0.65) and between subject comparisons (placebo p = 0.4 and drug p = 0.12). Metoclopramide has no significant prokinetic effect on gastric emptying in SHI patients when given in the early postinjury period.
