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...

The robot described in this paper, SUE (Supinator Extender), adds forearm/wrist rehabilitation functionality to the UCI BONES exoskeleton robot and to the ArmeoSpring rehabilitation device. SUE is a 2-DOF serial chain that can measure and assist forearm supination-pronation and wrist flexion-extension. The large power to weight ratio of pneumatic actuators allows SUE to achieve the forces neede...

This paper describes a WWW site that allows users to “leave the Web” and interact with the real world. An interdisciplinary team of anthropologists, computer scientists and electrical engineers collaborated on the project, desigining a system which consists of a robot arm fitted with a CCD camera and a pneumatic system. By clicking on an ISMAP control panel image, the operator of the robot dire...

This study aimed to examine the time course of endothelial function after a single handgrip exercise session combined with blood flow restriction in healthy young men. Nine participants (28 ± 5.8 years) completed a single session of bilateral dynamic handgrip exercise (20 min with 60% of the maximum voluntary contraction). To induce blood flow restriction, a cuff was placed 2 cm below the antec...

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...

BACKGROUND Pain due to injection propofol is a common problem. Different methods are used to decrease the pain but with limited success. The objective of this study was to assess the effect of injection dexmedetomidine 0.2 mcg/kg for prevention of pain due to propofol injection and compare it with injection lignocaine 0.2mg/kg. METHOD After taking permission of the Institutional Ethical Commi...

The literature supports the routine use of a tourniquet during total knee arthroplasty (TKA). With tourniquet use, there is decreased intraoperative blood loss with subsequent improved visibility and a bloodless surgical field. This facilitates efficiency with the potential for decreased operating time. Increased operating time has been associated with an increase in the incidence of infection ...

BACKGROUND The effects of cuff shape, timing of tourniquet application, and automated systems using limb occlusion pressure (LOP) have been reported to minimize the appropriate tourniquet pressure. However, studies on the raw material of the cuff itself to reduce the complications related to the tourniquet have been very rarely reported. The purpose of this study is to report the efficacy and s...
