ABSTRACT
Background: Fascia iliaca compartment nerve block (FICB) is commonly preferred pain management technique in femoral fractures. Dexamethasone and clonidine as adjuvants to local anesthetics have good analgesic effect with limited adverse effect. Aim and Objectives: To assess the efficacy of bupivacaine with clonidine, bupivacaine with dexamethasone, and bupivacaine alone in fascia iliaca compartment block in cases with femoral fractures. Materials and Methods: The present prospective randomized study included a total of 120 cases undergoing proximal femoral surgeries under subarachnoid block above 21 years. The study cases were randomly divided into three study groups, i.e. 40 participants in each group. Group 1 received 0.25% bupivacaine with 2 ml normal saline, Group 2 received 0.25% bupivacaine with 50mcg clonidine, and Group 3 received with 0.25% bupivacaine with 8mg dexamethasone. Parameters such as heart rate (HR), mean arterial pressure (MAP), systolic blood pressure (SBP), diastolic blood pressure (DBP), oxygen saturation levels, and visual analog scale (VAS) score was monitored and recorded. Results: The mean difference of HR between the study groups was statistically not significant (P > 0.005). The mean SBP, DBP, and VAS score was comparable between study groups. The mean analgesic duration in Group 1 was 6.01 h, in Group 2 was 13.58 h, and in Group 3 was 14.44 h. The mean difference of rescue analgesia requirement and duration of rescue analgesia was statistically significant. No adverse effects toward drugs were noticed. Conclusion: About 0.25% bupivacaine with 8 mg Dexamethasone had better analgesic duration and require minimal rescue analgesia in the first postoperative day than 0.25% bupivacaine with 50 mcg clonidine in cases undergoing femoral surgeries under FICB.
ABSTRACT
Background: Functional endoscopic sinus surgery is a minimally invasive surgical procedure performed under controlled hypotensive anesthesia. This technique has the advantage of minimal blood loss and visualizes surgical field distinctly. Aim and Objectives: To compare the efficacy of Dexmedetomidine and Esmolol for the induction of controlled hypotension in functional endoscopic sinus surgeries. Materials and Methods: A total of 80 cases with paranasal sinus pathologies posted for functional endoscopic sinus surgeries between 21 and 60 years were recruited. Study participants were randomly divided into two study groups, i.e. Group 1 administered with dexmedetomidine and Group 2 administered with Esmolol. Parameters such as hemodynamics, total intraoperative fentanyl consumption, duration of surgery, and total blood loss were noted. Results: The mean difference of systolic blood pressure, diastolic blood pressure and mean arterial pressure was not statistically significant (P > 0.05). The mean difference of heart rate between two study groups was statistically significant (P < 0.05). The mean duration surgery in Group 1 was 87.9 min and in Group 2 was 89.5 min. The estimated blood loss was 132.2 ml in Group 1 and 134.2 ml in Group 2. No desaturation was observed in the study participants during recovery and the postoperative period. Conclusion: Both dexmedetomidine and esmolol infusion are efficacious and are safe drugs for maintaining controlled hypotension and improve the quality of surgical field. Dexmedetomidine was associated with good postoperative sedation while esmolol associated with early recovery time. Surgeon satisfaction score was similar was similar in both groups.
