BACKGOUND: We evaluated the effect of intravenous lidocaine (1 mg/kg and 2 mg/kg) on intra-abdominal pressure (IAP) during endotracheal suctioning.
We studied 40 patients undergoing endotracheal intubation during mechanical ventilation. Group I (1 mg/kg) and group II (2 mg/kg)were given lidocaine double fashion. The endotracheal suctioning (ETS) was done 1, 3, 5 and 7 min after the injection of lidocaine. IAP, systolic blood pressure (SBP), diastolic blood preassure (DBP), and heart rate (HR) during ETS were recorded, IAP was measured using a transurethral bladder catheters. The cough response to ETS was classified as " cough score".
Before administration of lidocaine, ETS produced significant increase in SBP, DBP, IAP and HR compared with baseline values in the two groups (p<0.05). Both groups showed no significant changes in SBP, DBP, and HR during the study. In group I, ETS produced a significant increase in IAP 5 and 7min after lidocaine treatment (p<0.05). There were significant differences between the two groups 5 and 7 min after lidocaine treatment (p<0.05). The score of cough decreased significantly in both groups 3 min after lidocaine treatment but there was a significant difference between the two groups at 7 min.
We concluded that lidocaine pretreatment significantly blunted the increase in IAP, SBP DBP and HR caused by ETS and this effect lasts for 3 min in group I and 7 min in group II.
