popularity over the last two decades [1]. This new application of technology also facilitates spinal anesthesia in patients with challenging anatomy, such as those with scoliosis or obesity, or elderly patients [2,3]. Infiniti Plus (CIVCO Medical Solutions, Kalona, IA, USA) is a needle-guidance system that was recently developed to assist clinicians in performing ultrasound-guided nerve blocks....

Introduction: Analgesia following shoulder surgery commonly uses interscalene nerve blockade. When contraindicated (i.e. respiratory compromise), suprascapular nerve blockade can provide a viable alternative. Although a number of techniques have been used, Barber in 2005 described a simple method using anatomical landmarks. While theoretically straightforward, substantive evidence supporting th...

objectives this study aimed to examine the relationship between patients’ anthropometric characteristics and depth of spinal needle insertion to the subarachnoid cavity. patients and methods 385 patients with asa class i – ii, aged 18 - 65 years and undergoing elective surgery of the lower abdomen and extremities under spinal anesthesia, were selected for this cross-sectional study. the patient...

BACKGROUND Postdural puncture headache (PDPH), mainly resulting from the loss of cerebral spinal fluid (CSF), is a well-known iatrogenic complication of spinal anesthesia and diagnostic lumbar puncture. Spinal needles have been modified to minimize complications. Modifiable risk factors of PDPH mainly included needle size and needle shape. However, whether the incidence of PDPH is significantly...

post spinal puncture headache (psph) is a well known complication of spinal anesthesia. it occurs after spinal anesthesia induction due to dural and arachnoid puncture and has a significant effect on the patient’s postoperative well being. this manuscript is based on an observational study that runs on babol university of medical sciences and review of literatures about current concepts about t...

On the day of surgery, preoperative vital signs were blood pressure, 122/74 mm Hg; heart rate, 52 beats per minute and regular; hemoglobin saturation, 100% on room air; respirations, regular and nonlabored at 16 breaths per minute. Upon entry to the operating room, an 18-gauge intravenous (...

INTRODUCTION Our objective was to compare the effectiveness, speed, and complication rate of the traditional manually placed intraosseous (IO) catheter to a mechanical drill-assisted IO catheter by emergency medicine (EM) resident physicians in a training environment. METHODS Twenty-one EM residents participated in a randomized prospective crossover experiment placing 2 intraosseous needles (...

Radiofrequency heat lesioning has been advocated to prolong the duration of therapeutic effect of lumbar sympathetic block in Complex Region Pain Syndrome (CRPS) of the lower extremity. Prior to radiofrequency lesioning of the lumbar sympathetic trunk, sensory and motor stimulation may be used to verify that the active needle tip is not adjacent to a spinal nerve to avoid unwanted neural injury...

background the incidence of transient neurologic symptoms (tns) after spinal anesthesia with lidocaine is reported as high as 40%. objectives this prospective clinical trial was designed to determine the incidence of tns in patients who underwent spinal anesthesia with two different needles, in two different surgical positions. patients and methods the present randomized clinical trial was cond...
