Anaphylaxis during anesthesia is an unpredictable, severe, and rare reaction. It has an incidence of 1/10 000 to 1/20 000 surgeries. In most series, the responsible drugs include neuromuscular blocking agents, latex, or antibiotics. The frequency and etiology of systemic allergic reactions in other medical procedures are largely unknown. The identification of responsible drugs of anaphylaxis is a complex task, requiring testing of all medications and substances used during surgery. We describe our experience in a retrospective study of 15 patients...

With rapid improvement in healthcare in Saudi Arabia, increasing number of women with surgically corrected kyphoscoliosis are likely to present for cesarean section (CS) or vaginal delivery requiring anesthesia or analgesia. Despite the surgical correction, these patients have poor cardiopulmonary reserves which increase the risks associated with general anesthesia. Whereas altered vertebral anatomy from previous surgery and the presence of metal work in spine make performing of regional anesthesia (RA) difficult and unpredictable, we report anesthetic management of such a patient who underwent CS using continuous spinal anesthesia technique...

BACKGROUND: Hip arthroscopic surgery is performed on older pediatric patients. Fascia iliaca compartment block has proven efficacy in providing analgesia following hip surgery and can be performed with target location of local anesthetic below or above the inguinal ligament. The reported success of ultrasound-guided infra-inguinal fascia iliaca compartment block is lower when compared to traditional landmark technique, while the reliability of supra-inguinal fascia iliaca compartment block is unreported...

BACKGROUND: Previous studies have documented that single injection nearby the sciatic nerve bifurcation would influence the anesthesia and analgesia effect. But this is uncertain for preoperative continuous popliteal sciatic nerve block. So we conducted this trial to compare two paths (proximal to the bifurcation and at the bifurcation) of ultrasound guided continuous popliteal sciatic nerve block in foot and ankle surgery. METHODS: 40 recruited objects were randomly assigned to receive ultrasound-guided continuous popliteal sciatic nerve block at the puncture path proximal to the nerve bifurcation either at the nerve bifurcation...

BACKGROUND A case report of urethral diverticulum complicating pregnancy is presented. The diagnosis and management are challenging because of the rare nature of this condition, the varied presentations and differential diagnoses, and the possibility of misdiagnosis. CASE REPORT A 25-year-old primigravida with scheduled induction of labor at 39 weeks gestation due to gestational diabetes mellitus presented for a routine antenatal appointment at 38 weeks and four days. On digital cervical examination, she was found to have a large semi-solid anterior vaginal mass, shown by trans-vaginal ultrasound to have a nearly solid appearance of a 5×7 cm mass with septation...

PURPOSE OF REVIEW: Ultrasound has become readily available in the perioperative area. In this review, we aim to bring forth some uses of ultrasound beyond that in regional anesthesia. RECENT FINDINGS: Critical care and emergency physicians have embraced ultrasound in their respective fields. We as anesthesiologists and practitioners of acute care medicine are not immune to this penetration. There is been a lot of recent literature on the various uses of perioperative point of care ultrasound...

Ultrasound (US) performed at the point of care has found fertile ground in perioperative medicine. In the hands of anesthesiologists, transesophageal echocardiography (TEE) has become established as a powerful diagnostic and monitoring tool in the perioperative care of cardiac and non-cardiac patients. A number of point-of-care US (POCUS) applications are relevant to perioperative care, including airway, cardiac, lung and gastric US. Although guidelines exist to define the scope of practice for basic and advanced TEE, there remains a lack of such guidelines for perioperative point-of-care ultrasound (POCUS), despite a number of recent calls for action in the academic anesthesia community...

INTRODUCTION: Ultrasound is a portable and safe technology that is increasingly used to assist anesthetic procedures and has been integrated into the routine practice of a wide range of invasive procedures. As a complementary diagnostic tool, publications related to perioperative support other than vascular access and nerve blocks are currently lacking. EVIDENCE ACQUISITION: Given the growing interest of anesthesiologists in acquisition of knowledge and skills of ultrasound, we propose a systematic review of the diagnosis, decision making or change in perioperative management of non-cardiac surgical patients derived from ultrasound practice...

BACKGROUND: One of the main challenges in anesthesiology is difficult intubation. There are many anatomical parameters for evaluating the feasibility of tracheal intubation; one that can reliably predict a difficult intubation is the Cormack-Lehane classification obtained during direct laryngoscopy. This is an invasive procedure that cannot be performed in an awake patient or for pre-anesthetic airway assessments in patients with no prior history of tracheal intubation. Recently, ultrasound has been successfully used for several airway-related applications...

PURPOSE: Cyanoacrylate closure of the saphenous vein with the VenaSeal system is a new technique just approved on December 2016 in Korea. Therefore, there are seldom reports about postprocedural outcomes of VenaSeal system in Asian countries. We report the initial outcomes of VenaSeal system for the treatment of great saphenous veins (GSVs) and small saphenous veins (SSVs) as a first report in Korea. METHODS: Thirty-four patients with incompetent saphenous veins (47 GSVs and 16 SSVs) were treated at a single session...
