Popis: Objective.To determine if the measurement of gastricintramucosal pH (pHi) is useful for evaluation of circulatory status ofcritically ill pediatric patients. Design.Prospective clinicalstudy. Setting.General intensive care unit in a universityhospital. Patients.Seven pediatric patients (mean age: 2 y.o.);six post-cardiac surgery, one receiving barbiturate therapy.Interventions.Tonometric catheters were placed via nasogastricapproach. pHi was measured after confirmation of the catheter positionby X-ray. Measurements and main results.Saturation of venousblood oxygen (SvO2), arterial keton body ratio (AKBR), serumlactate level and pHi were evaluated simultaneously. No patientssurvived with pHi below 7.22; pHi above 7.11 significantly correlatedwith SvO2 values (r= 0.814, p< 0.001);pHi below 7.11 did not show any significant correlation withSvO2. Whereas SvO2 values of under 40% weredistributed in the pHi range from 7.11 to 7.19, pHi below 7.11 occurredwhen SvO2 values were more than 40%. AKBR and serumlactate level did not correlate with pHi. Conclusion.pHi can bea useful parameter for evaluating the circulatory status of criticallyill pediatric patients; it allows reliable evaluation of splanchnic andperipheral perfusion.
