Although laparoscopy is one of the most common surgical procedures done today, bowel perforations can and do occur during the initial insertion of the Veress needle and/or trocar. Recent advances in microlaparoscopy have reduced the morbidity of this complication when encountered. We report a case of small bowel perforation following insertion of a Veress needle with its 2 mm trocar and our min...

BACKGROUND Accurate identification of the epidural space is critical for safe and effective epidural anesthesia or treatment of acute lumbar radicular pain with epidural steroid injections. The loss-of-resistance technique is commonly used, but it is known to be unreliable. Even when it is performed in conjunction with two-dimensional fluoroscopic guidance, determining when the needle tip enter...

Necrotizing fasciitis is a severe life-threatening infection of the deep subcutaneous tissues and fascia. Infection with Vibrio vulnificus, a halophilic Gram-negative bacillus found worldwide in warm coastal waters, can lead to severe complications, particularly among patients with chronic liver diseases. We herein present an unusual case of necrotizing fasciitis caused by V. vulnificus trigger...

OBJECTIVES The purpose of this study was to determine the pain associated with needle insertion (with or without topical anesthetic) and solution deposition for the long buccal nerve block injection in patients with irreversible pulpitis. Initial pain and any differences by age and gender were also studied. STUDY DESIGN One hundred twelve emergency patients with irreversible pulpitis received...

This paper shows how to implement haptic rendering for a needle insertion problem with volume graphic model. The target is a spine biopsy simulator for tumor inspection by needle insertion. Simulated force is calculated from the relationship between voxel data and the orientation and position of the needle. At first, it is generated using PHANToM. The needle puncturing resistive force is calcul...

OBJECTIVE The study was designed to compare the insertion characteristics and incidence of PDPH between 25 gauge Quincke needle and 26 gauge Eldor needle for spinal anaesthesia in elective c/s. METHOD 60 pregnant women (aged 19-35 yrs and weighing 58 -67 kg) undergoing elective caesarean section were randomized into group A (Quincke spinal needle group) or group B (Eldor spinal needle group)....

Objective: We report a case of self inserted needle into the left ventricle heart and description our surgical intervention in psychiatric patient without decision-making capacity. discuss issues regarding obtaining consent this with sub-acute presentation, operative approach, summarize treatment approach based on review current literature. Methods: A PubMed search using terms “needle, “heart”,...

BACKGROUND Infection and epidural abscess are important complications of epidural analgesia. Difficult insertion may be associated with an increased risk of bacterial contamination of the epidural needle or catheter. METHODS Bacterial contamination of epidural needles and trocars after difficult epidural insertion, defined as two or more skin passes, was assessed in 38 obstetric and ten gynae...

Performance of neuraxial blockade using a midline approach can be technically difficult. It is therefore important to optimize factors that are under the influence of the clinician performing the procedure. One of these factors might be the chosen point of insertion of the needle. Surprisingly few data exist on where between the tips of two adjacent spinous processes the needle should be introd...
