OBJECTIVE: To compare gastric mucosal pH (pHi) and global oxygen variables [Oxygen Delivery Index (DO2I) and Oxygen Consumption Index (VO2I)] as indicators of adequacy of resuscitation after major trauma.
METHODS: Twenty-seven patients were prospectively randomized into two groups: group 1 (n = 11), normalization and maintenance of pHi at or above 7.30; and group 2 (n = 16), maintaining a DO2I of 600 and a VO2I of > 150. The groups had statistically similar injury severity scores, lactate, and base deficit.
RESULTS: The goals of therapy were achieved within 24 hours of admission in 10 of the 11 patients in group 1 and in 15 of the 16 patients in group 2. One patient (9.1%) in group 1 died. This patient had transient stabilization of pHi to 7.3 and subsequently had persistent mucosal acidosis. Of the 10 patients with pHi > 7.3 at 24 hours, 9 survived. In group 2, 5 (31.3%) died. Four of the 5 nonsurvivors had achieved DO2I and VO2I goals, but had pHi < 7.3 at 24 hours. A comparison of time taken for optimization of DO2I, VO2I, lactate, base excess, and pHi showed pHi and lactate as the variables different in survivors and nonsurvivors. Six of the 8 patients who developed multiple organ dysfunction syndrome had pHi < 7.3 at 24 hours. Persistently low pHi was the first sign of bacteremia (3 patients), small bowel gangrene or pregangrene (2 patients), intestinal anastomotic leak (2 patients), intra-abdominal hypertension (4 patients), and intra-abdominal abscess (5 patients). It was the first finding in all the nonsurvivors at least 72 hours before death.
CONCLUSIONS: pHi may be an important marker to assess the adequacy of resuscitation. pHi monitoring may provide early warning for systemic complications in the postresuscitation period.
