Abstract:

“Venous cannulation is often performed without any analgesia, even though pain experienced during this procedure is at times very distressing. Various pharmacological and nonpharmacological measures have been tried with variable results to minimize venous cannulation pain. We designed the present study to evaluate the efficacy of a flash of light on attenuating venous cannulation pain. Ninety adults (15-60 yr), ASA physical status I and II, of either sex, undergoing elective laparoscopic cholecystectomy, were included in this prospective and randomized study. Patients were divided into three groups of 30 each. Group I (control); Group II (distraction): photographed without a flash of light; and Group III (flash): photographed with a flash of light just before venous cannulation of a vein on the dorsum of the nondominant hand. Immediately after the photograph, venous cannulation was performed using an 18-gauge cannula. Two patients from each group could not be cannulated on their first attempt and were therefore dropped from subsequent analysis. The incidence of venous cannulation pain in the flash group was lower, i.e., 50% (14 of 28) when compared to 100% (28 of 28) observed in the other two study groups” (Agarwal et al 2008).
