Effects of Surgical Position on Blood Loss in Single Level Lumbal Disc Hernia Microsurgery

Abstract

Background: Lumbar disc herniation refers to the protrusion or rupture of intervertebral discs. Blood loss during spinal surgery can have substantial implications for patient outcomes, including the risk of complications, transfusion requirements, and length of hospital stay. Our study aims to compare the effects of two auxiliary materials used in spinal surgical procedures on surgical blood loss.

Methods: This study was conducted in two centers. This is a prospective, randomized, controlled trial. It included 100 participants. The study was conducted at two centers. The radiolucent spine surgery frame was utilized at one of them, while at the other center, thoracic gel rolls were employed. Body mass index, surgery duration, and bleeding are some variables examined in the study.

Results: No statistically significant difference among the groups regarding age, side, and gender variables (p>0.05). However, statistical analysis has revealed significant differences in the distribution of other analyzed variables, namely Body Mass Index, Duration of Surgery, and Amount of Bleeding, among the groups (p=0.03, p<0.01, and p=0.01, respectively). There is a significant positive correlation between body mass index and the amount of bleeding in both groups.

Conclusion: The effects of surgical position on blood loss in lumbar disc hernia microsurgery remain a topic of ongoing research. Assessing other important perioperative outcomes would provide a more comprehensive understanding of the impact of devices like spine surgery frames and gel rolls on the surgical process
