UNLABELLED The mechanism of tourniquet-induced arterial pressure increase is not known. We investigated the effect of preoperative ketamine on tourniquet-induced arterial pressure and heart rate changes in 85 patients undergoing knee surgery with a tourniquet under general anesthesia. Patients were randomly assigned into three groups; Large Ketamine (n = 28; ketamine 1.0 mg/kg), Small Ketamine ...

BACKGROUND Intravenous Regional Anesthesia (IVRA) is a well-known technique for producing analgesia during surgical procedures in the extremities. However, the rapid onset of pain following the deflation of a double-cuff tourniquet during IVRA is a serious disadvantage, leading patient suffering. OBJECTIVES The aim of this study was to evaluate the clinical effectiveness of a pneumatic arm to...

BACKGROUND The aim of this study is to evaluate the effects of tourniquet release before wound closure for hemostasis or after wound closure in cemented total knee arthroplasty (TKA). METHODS We conducted a meta-analysis and review work on relevant clinical outcomes to evaluate the effects of the timing of tourniquet release in cemented TKA. Electronic databases were searched for relevant ran...

background: the pneumatic tourniquet (pt) is routinely used in upper and lower limb operations by most orthopaedic surgeons. the silicone ring tourniquet (srt) was introduced in clinical practice the last decade. clinical as well comparative studies in volunteers concerning its safety and efficacy have been published. the aim of this study was to investigate the postoperative effect of the sili...

BACKGROUND In patients undergoing total knee arthroplasty, intraoperative pulmonary embolic events are rare, and most occur following tourniquet deflation. This embolization can be observed using transesophageal echocardiography. However, the authors have encountered sudden decreases in arterial oxygen partial pressure while a tourniquet is still inflated. Therefore, the current investigation w...

BACKGROUND To assess the effects of tourniquet use in arthroscopic anterior cruciate ligament (ACL) reconstruction surgery. METHODS We conducted a systematic review and meta-analysis of randomised controlled trials (RCTs) that compared surgical outcomes following tourniquet use against non-tourniquet use during ACL reconstruction surgery. We searched the Cochrane Central Register of Controlle...

BACKGROUND The purpose of this research is to evaluate the effects of a tourniquet in total knee arthroplasty (TKA). METHODS The study was done by randomized controlled trials (RCTs) on the effects of a tourniquet in TKA. All related articles which were published up to June 2013 from Medline, Embase, and Cochrane Central Register of Controlled Trails were identified. The methodological qualit...

PURPOSE: Carpal tunnel syndrome is a common cause of upper extremity discomfort. Surgical release of the median nerve can be performed under general or local anesthetic, with or without a tourniquet. Wide-awake carpal tunnel release (CTR) (local anesthesia, no sedation) is gaining popularity. Tourniquet discomfort is a reported downside. This study reviews outcomes in wide-awake CTR and compare...

The effect of the pneumatic tourniquet on the incidence of postoperative deep venous thrombosis is uncertain. We carried out a controlled study comparing the incidence of deep venous thrombosis when a tourniquet was used with the incidence when a tourniquet was not used. Thrombosis was detected by radioisotope venography. The results of the study showed no difference in incidence and we conclud...

An unusually wide pneumatic tourniquet has recently become available; we provide a simple formula for its use with a low but effective inflation pressure. A prospective, randomised and controlled trial in 600 lower limb and 150 upper limb operations is reported. The wide tourniquet (12.5 cm) was as effective at low pressure as was a conventional tourniquet (9 cm) inflated to significantly highe...
