Comparative effect of 6% hydroxyethyl starch (containing 1% dextrose) and lactated Ringer's solution for cesarean section under spinal anesthesia.

Purpose: This study aimed to compare low-molecular weight hydroxyethyl starch containing 1% dextrose (HES) infusion and lactated Ringer's solution (LR) in the prevention of hypotension associated with spinal anesthesia for cesarean section.

Methods: Sixty-seven patients scheduled for cesarean section under spinal anesthesia were randomly allocated to receive either LR ( n= 35) or HES ( n= 32) infusion before cesarean delivery. Infusion of the fluid was started immediately after arrival at the operating room, through two fully open i.

[The effects of H2 blockers on gastric flora and sputum culture].

Gastric juice and sputum of 12 patients, who had entered the intensive care unit postoperatively and received respiratory management, were examined for bacteria and their relationship with gastric pH was investigated. Gastric bacteria were detected in only 3 specimens out of 14 (21.4%) when the pH was under 3.
