BACKGROUND: Opioids have been the mainstay of treatment in the physiologically young geriatric hip fracture patient undergoing total hip arthroplasty (THA). However opioid-related side effects increase morbidity. Regional anesthesia may provide better analgesia, while decreasing opioid-related side effects. The goal of this study was to examine the effect of perioperative continuous femoral nerve blockade with regards to pain scores, opioid-related side effects and posthospital disposition in hip fracture patients undergoing THA...

Most diagnostic testing in patients with anomalous aortic origins of coronary arteries, myocardial bridges, and coronary artery changes after Kawasaki disease are performed with the use of noninvasive techniques. In some cases, however, further diagnostic information is needed to guide the clinician in treating these patients. In such instances, cardiac catheterization with invasive anatomic and functional testing is an invaluable tool. Moreover, interventional treatment in the cardiac catheterization laboratory may be performed in a small subset of these patients...

We documented brachial plexus injury by electromyography and magnetic resonance imaging secondary to needle sticks for central line insertion. This type of complication is rare in the literature, as few case reports exist. Brachial plexus injury can happen because of anatomic variations. Nevertheless, multiple attempts or introducer needle rotations should be avoided during subclavian vein catheterization. Pain that emerges in the ipsilateral arm after subclavian catheter placement should be taken into serious consideration...

OBJECTIVES: Fetal lower urinary tract obstruction (LUTO), most often associated with presence of posterior urethral valves, poses high risk of perinatal mortality or postnatal renal failure. Looking for a method of causative treatment we have devel-oped a technique of fetal urethroplasty with a coronary angioplasty balloon catheter inserted under an ultrasonographic guidance via an 18-gauge needle introduced transabdominally to fetal bladder. MATERIAL AND METHODS: We have used this procedure in three women with singleton pregnancies (two primiparas and one multipara, 32-35 years of age), diagnosed with fetal megacystis at 12-16 weeks of gestation...

REVIEW
Osaree Akaraborworn
Central venous catheterization is widely used in the emergency setting. This review aims to assess central venous catheterization from the perspectives of types of catheters, sites of insertion, and techniques. In emergency conditions, non-tunneled catheters are preferred because the technique for its insertion is not complicated and less time-consuming. The size of catheter depends on the purpose of catheterization. For example, a large bore catheter is needed for rapid infusion. The ideal catheterization site should bear fewer thromboses, lower infectious rate, and fewer mechanical complications...
