Abstract: (161 Views)
Background: In general anesthesia, anesthetic agents are administered by inhalation or intravenously, leading to loss of consciousness, immobility, analgesia, and amnesia. In spinal anesthesia, injection of a local anesthetic into the intrathecal space causes sensory and motor block. The aim of this study was to compare the volume of bleeding during cesarean section under general anesthesia and spinal anesthesia.
Methods: This study is a cross-sectional prospective study. The gauzes used were weighed before the operation and bloody gauzes were weighed after the operation. The difference between the weight of bloody and dry gauzes was recorded as the volume of bleeding. This volume was then added to the volume of blood in the suction chamber and the final bleeding volume was estimated.
Results: 70 patients who were candidates for cesarean section were included in the study. The mean age of the patients included in the study was 24.82±4.98 and their mean weight was 77.11±8.97. The mean hemoglobin in the spinal anesthesia group was 91.12±39. Volume of bleeding during cesarean section by spinal anesthesia was significantly less than general anesthesia (P=0.001). Also, the visual estimation of bleeding in spinal anesthesia was significantly lower than general anesthesia (P<0.001). In this study, there was no significant difference between heart rate, systolic and diastolic pressure before and during surgery, and the first- and fifth-minute Apgar scores between the two groups of general and spinal anesthesia.
Conclusion: We found in this study that the volume of bleeding during cesarean section under spinal anesthesia is less than general anesthesia. It is suggested that in future studies, other methods of estimating bleeding such as postoperative hemoglobin reduction, dilution method, atomic absorption spectroscopy and photometry be used. Also, a comparison should be made between the three groups of general, spinal and epidural anesthesia, and the volume of bleeding in each should be checked and the best anesthesia method should be selected for cesarean section.
