background and objective: considering the wide side effects of synthetic pain killers, use of herbal drugs in folk medicine as analgesic agents has increased. in the present work, we tried to uncover the pharmacological potential of ethanolic extracts by using various animal models and also to explore the potent antinociceptive effect of the plant thymus kotschyanus. materials and methods: the ...

Background: Bier block is a reliable technique used in extremity surgeries. Typically, angiocatheters are palced in the distal portion of the extremity that is going to be operated. Although, it is not the case in every operation. Therefore, determining the effectiveness of the local anesthetic injection site on the quality of the upper-extremity block can be helpful. Methods: In this double-b...

We have compared the analgesic potency of MAC-equivalent concentrations of xenon (10, 20, 30 and 40%) and nitrous oxide (15, 30, 45 and 60%) in humans using a multimodal experimental pain testing and assessment technique. We tested 12 healthy volunteers in a randomized, single-blind, crossover study. The following experimental pain tests were used: nociceptive reflex to repeated stimuli; pain t...

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...

The protective effect of local hypothermia was studied in pig's limbs made ischaemic by long, repeated application of a pneumatic tourniquet. Twenty-one Landrace pigs were anaesthetised on two separate occasions six days apart and a pneumatic tourniquet at 500 mmHg pressure was applied to the same forelimb for three and two hours respectively. Ten of the pigs had local hypothermia from cold gel...

CASE REPORT A 28-year-old Connecticut woman had fever and rash 3 days after returning from the Dominican Republic. During her trip, she ate the food, drank the water, and suffered many mosquito bites. The rash involved her neck, chest, and extremities. Accompanying the rash, she had chills, fever, headache, and malaise. She had no arthralgias, myalgias, or diarrhea. During childhood, she immigr...
