“…A study comparing systemic Responses to Tourniquet Release observed that children tolerated tourniquet release with less hemodynamic change as compared to adults where tourniquet deflation resulted in significant decreases in blood pressure [30] . In another study, Moncorge et al [31 ], who studied 11 children, found that systolic blood pressure fell and pulse increased by 15 mm Hg and 12 beat per min, respectively. We also found similar hemodynamic changes on tourniquet deflation in either of the groups except two patients in placebo group who developed sinus tacchyarrhythmias immediately after deflation.…”

Background: Pneumatic Tourniquets are commonly used in orthopaedic surgery of the extremities to reduce bleeding and to provide a clear field to the surgeon, but severe pain often complicates the tourniquet inflation. Although the mechanism of tourniquet induced hypertension (TIH)is not well understood, the autonomic nervous system plays an important role. Hence, Dexmedetomidine, a potent a2-adrenoceptor agonist may prevent hyper adrenergic responses and can be of prophylactic value for tourniquet induced hypertension. Methods: Forty American Society of Anesthesiologists (ASA) physical status class I and II children, aged 5-12 years, posted for Orthopaedic surgery of upper limbs under general anaesthesia with tourniquet application were included in the study. They were randomly assigned to receive intravenous Dexmedetomidine (Group D; n=20) or normal saline (Group C; n=20) before tourniquet inflation. Incidence of TIH, Mean Arterial blood pressure and heart rate were recorded. Results: There were no significant differences between the baseline characteristics. The incidence of TIH in group D was significantly less than the group C (20%) as compared to group D (70%).There was significant increase in the heart rate of placebo group after 30 minutes of tourniquet inflation while there was minimal variability of heart rate in the group D. In the group D, arterial pressure was not significantly changed, but in the group C, the arterial pressure was significantly increased after 20 minutes of tourniquet inflation. No significant adverse effects were noted in any group. Conclusion: Preoperative low dose intravenous Dexmedetomidine prevents tourniquetinduced hypertension in paediatric patients undergoing general anaesthesia for upper limb surgeries.

A new technique for autologous fat harvesting is presented. It is termed the "no-touch" technique because the concentrated fat graft is obtained with no handling of fatty tissue. With the no-touch technique, fat aspiration is performed under tourniquet. There is no need for any mechanical manipulations such as centrifugation, washing, whisking, filtering, or straining. The medial aspect of the knee is used as the donor area. Fat is aspirated through a disposable 10-ml syringe and a 14-gauge microcannula, which consists of a curved, semiblunted tip such as that of the Tuohy needle. What remains in the syringe is the concentrated fat without blood, serum, or lidocaine. The authors report their experience with 30 patients.
