Anand Agricultural University, Anand

Anand Agricultural University (AAU) was established in 2004 at Anand with the support of the Government of Gujarat, Act No.(Guj 5 of 2004) dated April 29, 2004. Caved out of the erstwhile Gujarat Agricultural University (GAU), the dream institution of Sardar Vallabhbhai Patel and Dr. K. M. Munshi, the AAU was set up to provide support to the farming community in three facets namely education, research and extension activities in Agriculture, Horticulture Engineering, product Processing and Home Science. At present there seven Colleges, seventeen Research Centers and six Extension Education Institute working in nine districts of Gujarat namely Ahmedabad, Anand, Dahod, Kheda, Panchmahal, Vadodara, Mahisagar, Botad and Chhotaudepur AAU's activities have expanded to span newer commodity sectors such as soil health card, bio-diesel, medicinal plants apart from the mandatory ones like rice, maize, tobacco, vegetable crops, fruit crops, forage crops, animal breeding, nutrition and dairy products etc. the core of AAU's operating philosophy however, continues to create the partnership between the rural people and committed academic as the basic for sustainable rural development. In pursuing its various programmes AAU's overall mission is to promote sustainable growth and economic independence in rural society. AAU aims to do this through education, research and extension education. Thus, AAU works towards the empowerment of the farmers.

    EFFECTS OF MONOPOLAR AND BIPOLAR ELECTROSURGICAL UNIT ON ABDOMINAL WALL, MESENTERIC ARTERIES AND SMALL INTESTINE OF RABBITS (Oryctolagus cuniculus)
    (AAU, Anand, 2011) ALASE, ASHWINI LAXMAN; PATIL, D. B.
    Electrosurgery is one of the most often and routinely used surgical tool for tissue cutting and coagulation, with thermal damage extending to hundreds of micrometers. The desired therapeutic result of electrosurgery is controlled tissue destruction at the site of the active electrode, with no effect at any other location, including the site of the dispersive electrode. However, the degree of thermal damage produced by this instrument is often suspected to be extensive. This study was undertaken to assess the thermal damage caused by Monopolar and Bipolar electrocoagulation at clinically relevant different power outputs and durations of applications on mesenteric arteries having 2 mm diameter, small intestine and abdominal wall in rabbits in order to avoid the side effects for the safer surgery without hazards. After the rabbits were anesthetized with xylazine-ketamine-diazepam mixture, and laparotomy performed. Monopolar and Bipolar electrodes were applied on the muscular part of the abdominal wall without skin, mesenteric arteries and jejunum. Each of the different power outputs viz., 24 Watts (W), 56 W and 72 W were applied for 1 second (sec), 2 sec and 3 sec. The animals were sacrificed and the tissue samples were fixed and embedded in paraffin before sections were taken and stained. Using light microscopy and morphometric imaging analysis, the area of lateral thermal damage of Aabdominal muscles was measured at the point of application of electrode. The quality of coagulation and thermal damage in mesenteric arteries, jejunum, and abdominal muscles were statistically evaluated for differences between Monopolar electrocoagulation and Bipolar electrocoagulation at different power outputs and durations of applications (Univariant analysis). In mesenteric arteries with 2 mm diameter, good quality of coagulation with minimum thermal damage was achieved at 24 Watts for 2 and 3 seconds of application and at 56 W for 1 second application by Monopolar electrocoagulation. Bipolar electrocoagulation showed good quality of coagulation with minimum thermal damage at 24 W for 3 seconds application and at 56 W for 1 and 2 seconds of application. Monopolar electrocoagulation of jejunal serosa caused more thermal damage to the wall of jejunum than Bipolar electrocoagulation and the damage extended upto tunica musculosa at lowest power output (24 W) and upto tunica mucosa at highest setting (72 W). The mean area of abdominal muscle damage caused by Monopolar electrocoagulation was significantly greater than that of Bipolar electrocoagulation. Irrespective of the tissue, based on histopathology and morphometry. Monopolar electrocoagulation caused greater thermal damage as compared to that of Bipolar electrocoagulation and the thermal damage increased with increase in power output and duration of application. Thus, whenever Monopolar Electrosurgical unit is to be used, the power output and the duration of application should be kept as low as possible.
