Background: To analyse use of monopolar diathermy stimulation of pedicle screws in order to improve breach detection. Methods: Prospective single-blind study. Patients with preoperative neurological deficit excluded. Pedicle screws inserted freehand into thoracic and lumbar spine. Monopolar diathermy in “cutting” mode at half the strength used for actual cutting purpose was used to stimulate th...

Therapy using pulsed electromagnetic energy is now used widely in the UK and many claims are made regarding its clinical effectiveness. The technique developed about 40 years ago from that of continuous short-wave diathermy, to which it is similar in many respects. There are, however, certain important differences between these therapies that influence significantly their clinical application. ...

Background and Objectives: To compare the efficacy of three surgical methods in tonsillectomy patients; combination monopolar bipolar diathermy (diathermy), coblation dissection using Evac (coblation), Harmonic scalpel assisted (harmonic). Materials Methods: Ninety-seven patients underwent a single institute between January 2020 May 2021. Postoperative pain was evaluated visual analogue scale (...

Objective: To estimate the frequency of gallbladder perforation with conventional Monopolar Diathermy versus Harmonic scalpel in laparoscopic cholecystectomy.
 Study Design: Quasi-experimental study.
 Place and Duration Study: Department Surgery, Combined Military Hospital, Quetta Pakistan, from Sep 2018 to 2019.
 Methodology: A total 160 patients undergoing cholecystectomy for s...

HYPOTHESIS New hemostatic methods have been widely used in open and laparoscopic surgery. The LigaSure Precise diathermy system (Valleylab, Boulder, Colo) has been recently used in thyroid surgery. We hypothesized that its use could lead to reduced operative time and fewer complications compared with conventional knot tying in total or near-total thyroidectomy. DESIGN Prospective case-control...

The principles governing the passage of high frequency currents through various conductors have been discussed and exemplified in experiments done on both non-living and living bodies. In Part I it was shown: (1) That the current takes the path of least electrical resistance rather than the shortest path; (2) that maximal heating occurs at the point of greatest concentration of the lines of cur...

BACKGROUND Delayed onset muscle soreness (DOMS) occurs following unaccustomed or intense bouts of exercise. Previous research has demonstrated that that preconditioning with low load exercise or heat relieves muscle soreness. However, actively warming up the muscles with exercise may be an effective alternative. OBJECTIVES This study compared preconditioning effect of light load eccentric exe...

MANY different explanations have been put forward to account for the phenomenon of late-phase fluorescence in fluorescein fundus photography. Until the exact mechanism is known, its value as a tool for the diagnosis of fundus pathology is limited. It seems quite clear that localization of fluorescein does occur in spite of the statement by Schiller, Schayer, and Hess (1953) that aqueous fluores...

Over the last century electrocautery has emerged as an imperative adjunct to surgery across the entire range of surgical disciplines. A diathermy machine converts electricity of the main supply (240V; 50 Hz) into high frequency current (>100,000 Hz) to minimize the risk of electrical shocks. In monopolar mode, the current from the diathermy enters the patient through the active electrode and ex...
