Bipolar Diathermy versus Conventional Cold Dissection Method a comparison of Mean Operative Blood Loss.
Pak J Med Health Sci Jan ;12(3):953-6.

Background: Intra-operative hemorrhage is the most significant complication in tonsillectomy. No previous study has been done to assess the efficacy of bipolar diathermy regarding intra-operative blood loss during tonsillectomy in local population so far. Aim: To compare the mean intra-operative blood loss during tonsillectomy using bipolar diathermy versus cold dissection method. Methodology : A Randomized Controlled Trial was carried out in the ENT Department, The Children’s Hospital , Lahore within six months (1st February 2017-31st July 2017) on 100 patients divided in 2 equal groups i.e. patients to be operated with bipolar diathermy ( group B) and operation with cold dissect ion procedure ( group C). After taking consent from patient they were operated as the first case in operation list. Anesthetist was not aware of the type of procedure opted for a specific patient. After anesthetizing the patient, same type of surgery (tonsillectomy with bipolar diathermy and cold dissection ) was performed on both group patients by same surgeon under same operative environment. Post-operatively patients were kept in recovery and then shifted to the ward. Operative blood loss was measured by direct method. Results : Male predominancy was observed in the current study (male-female ratio in group B :1.5:1 and in group C:1.6:1 ) The Mean+/-SD of the ages were 10.78+/-3.25 years and 11.14+/-3.68 years respectively. The mean operative blood loss presents statistically significant difference between two groups B and C (P<0.05). Conclusion: Bipolar diathermy is an effective and safe technique in pediatric patients. Advantages were observed in terms of shorter operative time and minimal intra-operative blood loss.
