Objective: We aimed to evaluate the effect of bupivacaine and to compare the routes of administration of bupivacaine in the management of postoperative incision site pain after thyroidectomy. Material and Methods:Consecutive patients who were planned for thyroidectomy surgery were randomized into three groups of 30 patients each: Group 1 (control group): standard thyroidectomy surgery without additional intervention; Group 2 (paratracheal infiltration with bupivacaine): following thyroidectomy, 0.25% bupivacaine was applied on the surgical area; Group 3 (subcutaneous infiltration with bupivacaine): following thyroidectomy, 0.25% bupivacaine was injected into the cutaneous, subcutaneous region and fascia of the surgical area. Postoperative pain was evaluated by a visual analog scale (VAS) at 1 st , 4 th , and 12 th hours after thyroidectomy. Total daily requirement for additional analgesia was recorded. Results:The mean age of 90 patients was 44.37±13.42 years, and the female:male ratio was 62:28. There was no difference between study groups in terms of age, thyroid volume, TSH and T4 levels. VAS score of patients in paratracheal infiltration with bupivacaine group was significantly lower than control group patients at 1 st , 4 th and 12 th hours following thyroidectomy (p=0.030, p=0.033, p=0.039, respectively). The need for analgesics was significantly lower in both paratracheal infiltration and subcutaneous infiltration groups than the control group (86.7%, 83.0%, and 73.3%, respectively, p=0.049). Conclusions:Intraoperative local bupivacaine application is effective in decreasing postoperative pain in patients with thyroidectomy.
The purpose of this paper was to analyze the effect of Valsalva maneuver application before finalizing thyroidectomy operations on the identification of bleeding points and postoperational drainage. One hundred patients (age range, 24-76 years) with multinodular goiter, recurrent multinodular goiter, toxic diffuse multinodular goiter, or papillary thyroid cancer were included in the study and were divided into 2 groups of 50 randomly. Both groups underwent thyroidectomy operation, only 1 group received intraoperative Valsalva maneuver application (twice, 30 seconds of 30-cm PEEP). The size of the thyroid gland, the duration of operation, hospital stay, and drain usage were reported. Postoperational occurrences of drainage, hematoma, reoperation, and additional complications were compared between the groups. Valsalva maneuver application helped to identify minor bleeding points in 32% of the cases. There was no significant difference between the study groups regarding the thyroid gland size, operation duration, hospital stay, and the duration of drain usage (P . 0.05 for all). The amount of drainage as well as the frequencies of hematoma, reoperation, and further complications was not significantly different between the study groups (P . 0.05 for all). Intraoperative application of Valsalva maneuver is only useful to detect minor bleeding points in some patients during thyroidectomy operations, but it had no effect on the duration of postoperative drain usage, the amount of drainage, and risk of hematoma. Therefore, intraoperative application of Valsalva maneuver has no beneficial effect on postoperative hemorrhagic complication after thyroidectomy operations.
