Moreover, post-operative wound infection or surgical site infection (SSI) delays return to gainful employment and prolong hospital stay. The objective of closed suction drainage of an established surgical site wound collection is to facilitate treatment of such collection with the aim of increasing patient’s comfort, decreasing patient morbidity and decreasing the length of hospitalization. AIMS/OBJECTIVES: 1. To evaluate the role of closed suction drainage in reduction of surgical site infection in elective laparotomy wounds as compared to laparotomy wounds closed without suction drainage. 2. To study the effect of closed suction drainage in reducing the hospital stay. METHODS: Study group consists of patients with suction drain in wound closure, while controls were patients w...

It is found that the antenna shows dual band characteristics with resonant frequency at 4.76 and 6.79 GHz. The dual nature of the antenna is realized by loading shorting pin with U-slot loaded patch. The lower and upper frequency bands are achieved as 443 and 287 MHz respectively. It is noted that the antenna shows frequency ratio of 1.4.
