Normal saline or air is used to identify loss of resistance during identification of the epidural space for combined spinal-epidural analgesia. Following epidural needle placement using air for loss of resistance, up to 80% of parturients move, grimace, vocalise or experience paraesthesia or dysaesthesia during subsequent dural puncture by a spinal needle. We compared the effects of saline vers...

BACKGROUND How smoothly insulin is injected is one of the major concerns when patients commence insulin injection therapy. Improving its usability may be important in initiation therapy and adherence, resulting in clinical benefits to the patient. METHODS In a single-center, open-label and randomized two-period crossover trial, the effect of the tapered needle of NanoPass (33 gauge, 5 mm) on ...

AIM To assess technical and lesion related factors affecting the quality of ultrasound guided core needle biopsy (CNB) of musculoskeletal soft tissue tumors. MATERIALS AND METHODS Data of 223 CNBs were evaluated in a retrospective study. Diagnostic yield was calculated for all lesions on the basis of lesion location (extremity/torso), examiner, biopsy needle gauge/length and number of acquire...

BACKGROUND Endobronchial ultrasound (EBUS)-guided transbronchial needle aspiration (TBNA) of mediastinal lymph nodes has been found to be more accurate than standard TBNA in the setting of malignancy. In patients with suspected sarcoidosis, the smaller ultrasound needle may yield inadequate material to make a histologic diagnosis of granulomatous inflammation. The aim of this study was to compa...

BACKGROUND The purpose of this study was to evaluate the effect of needle type on pain and bleeding during oocyte pick-up (OPU). METHODS From May through November 2013, patients undergoing OPU from a single follicle without any analgesic treatment were including this study. Eligible patients (n=75) were randomized 1:1 to undergo the procedure with either a reduced needle (17 gauge body, 20 ga...

OBJECTIVES To demonstrate a novel approach to cricoarytenoid joint (CAJ) injections. STUDY DESIGN Anatomic feasibility study. METHODS Five human cadaveric larynges providing 10 CAJ s were used to obtain trajectory measurements of a 27-gauge 1½-inch needle placed between the CAJ capsule and the contralateral cricothyroid membrane. Ten additional larynges providing 20 CAJ s were then used to ...

Sir, We appreciate the interest of Patnaik S [1] in our paper published in Journal of Orthoapedic Case Reports [2] and thank him for sharing his experience with the technique. We shall answers the queries raised sequentially. We are routinely using 16 or 18 gauge needle depending on the size of the child and in very young child infant a 18 gauge needle is enough. The trick is to tense the tendo...

BACKGROUND The liver sampling technique in dogs that consistently provides samples adequate for accurate histopathologic interpretation is not known. HYPOTHESIS/OBJECTIVES To compare histopathologic results of liver samples obtained by punch, cup, and 14 gauge needle to large wedge samples collected at necropsy. ANIMALS Seventy dogs undergoing necropsy. METHODS Prospective study. Liver sp...

Laparoscopic gastric surgeries are routinely performed with use of a nasogastric tube to decompress the upper gastrointestinal tract. A distended upper gastrointestinal tract can complicate successful laparoscopic gastric surgery as the distention compromises not only the visual field but also the laparoscopic manipulation of the stomach. Since nasogastric intubation is not without risks, we ha...

Endoscopic transmural drainage by using endoscopic ultrasound (EUS) guidance is not always safe because of the risk of bleeding and perforation. Additionally, the effective area of the EUS-guided procedure using a large diameter needle is relatively narrow. We evaluated the effectiveness and safety of EUS-guided drainage using fine needle and stiff fine guidewire without electrocautery. From No...
