Abstract
Background: Teenage pregnancy has been categorized as high-risk pregnancy due to immature growth of pelvis.The difference of spinal curvature affects the distribution of local anesthesia and complications from spinal anesthesia.
Objective: To determine the difference of onset in local anesthesia spreading via subarachnoid space as well as its complications between teenage and normal pregnancy.
Setting: Buriram Hospital
Design: Prospective observational study
Methods: After the approval from Buriram’s ethic committee, 119 pregnancy patients who undergone cesarean section with spinal anesthesia during October 2012 to April 2013 were blinded to a single anesthesiologist in terms of their age. After the anesthetic procedure, the patients were estimated the onset of anesthesia (defined as the time from spinal injection to loss of sensation at 4th thoracic level). Rates of intra-operative and post-operative complications were obtained.
Results: Sixteen patients were included into teenage pregnancy group (13.4%). There was no significant difference of spread time to the 4 thoracic level (2.75 vs 3.04 minutes, p= 0.819), as well as intra- and post-operative complications (p > 0.05) between teenage pregnancy and control group. Remarkably, the data showed that rate of local anesthesia spreading in the first minute in teenage pregnant group was significantly faster than the control group (p = 0.024).
Conclusion: The onset of local anesthesia spreading was not difference between two groups but the rate of local anesthetic drug spreading in the first minute in teenage pregnant group was significantly faster than the control group (p = 0.024). There was no significant difference of complications found in this study.
