RONCO M, Ricardo; RODRIGUEZ C, José I.; CERDA S, Mario  y  PARIS M, Enrique. Intramucosal gastric pH and prognosis in children with shock. Rev. chil. pediatr. [online]. 1998, vol.69, n.2, pp.60-63. ISSN 0370-4106.  http://dx.doi.org/10.4067/S0370-41061998000200003.

Objective:, to determine if intragastric mucosal pH [pHij measurement offers useful information on hemodynamic conditions and contributes to delineate prognosis in children with shock. Portents and methods', seven parents cged 4 to 14, mean 8.5 years with shock and requiring pulmonary artery catheter were included. All of them underwent pHi determinations simultaneously with arterial pH (pHa], oxygen delivery index [IDC^I, oxygen consumption index |IVO2|, mixed venous saturation [SvOjl and arterial blood lactate concentration which were measured every 6 hours along a 24 hour period. Results: a significant inverse correlation was found between IDO2 and pHi (r = -0.85) (p ~ OO1). There were not relationships between blood lactate, pHa, or SvO2 and pHi. Mean arterial blood lactate concentration was higher in non survivors (3.53 vs. 1.59 mmol/l; p = 0.051). Conclusion: a significant relationship between pHi and IDC>2 was found, but -n the opposite direction of what was "physiologically" expected. pHi did not correlate with mortality in this particular series of patients.

Palabras clave : shock; intragastric intramucosal pH; tonometry; gastric.
