Comparison of the efficiency and side effects of different size syringes in spinal anesthesia.

Abstract

INTRODUCTION[|]Obstetric anesthesia and analgesia aim to reduce the pain during the labor. In this study we investigate the effect of 3 different sized injectors (2.5 ml, 5ml, 10 ml) containing the same volume of local anesthesics to the level of subarachnoid block, complications and the patient hemodynamics.[¤]METHODS[|]120 ASA I-II patients in 18-45 age group who would undergo C-section wtih subarachnoid anesthesia were enrolled in our study. In Group I 2.5 ml injectors, in Group II 5 ml injectors and in Group III 10 ml injectors were used. Hemodinamics parameters were recorded. Postoperative Bromage scales and Pinprick tests were performed for motor and sensorial block levels and time for recovery of the blocks were also recorded. Postoperative complications (headaches, lomber pain) and the cases requiring epidural blood patches were noted.[¤]RESULTS[|]There was statatistically significant difference between the Group I and Group II about the time to reach T4 dermatome (p=0.002). It was 2.5+-0.8 min for Group I, 3.2+-0.9 min for Group II and 3.2+-1.0 min for Group III (Group I vs Group II p=0.001, Group I vs Group III p=0.002, Group II vs Group III p=0.843).[¤]DISCUSSION AND CONCLUSION[|]We think that the change in the diameter of the injector will produce a minimal hemodinamic parameters. Further studies with other patient groups with different surgical procedures will produce more comprehensive results.[¤]
