Monitoring the injured brain is an integral part of the management of severely brain injured patients in intensive care. There is increasing interest in methods to monitor global and regional cerebral oxygenation. There have been significant advances in analysing tissue oxygenation and local metabolites in the injured brain over the past decade. Cerebral(More)
BACKGROUND Although fluoroscopy is an established imaging modality for pudendal nerve block, ultrasound (US) technique allows physicians better visualization of anatomic structures. This study aimed to compare the effectiveness and safety between the US- and fluoroscopy-guided techniques. METHODS A randomized, single-blind, split-plot design was used to(More)
A hypersensitivity reaction, either anaphylactic or anaphylactoid, is a well-known adverse effect following intravenous and oral administration of vancomycin. The authors report a case of circulatory collapse and its management after the topical application of vancomycin powder during spinal instrumentation surgery. A 52-year-old woman with breast cancer(More)
STUDY OBJECTIVE To study the role of magnesium sulphate (MgSO4) on analgesic requirement, pain, discomfort, and sleep during perioperative period. DESIGN prospective, double-blinded, randomized study. SETTINGS Operating room and recovery ward at a university teaching hospital. PATIENTS 50 ASA physical status I and II patients scheduled for elective(More)
In this case report, we are the first to describe the occurrence of a pneumothorax after ultrasound-guided supraclavicular block. The block was performed using a medial-to-lateral in-plane needle insertion technique. The predisposing operator, technical, and patient factors as well as strategies for preventing this uncommon yet potentially severe(More)
Recent animal studies have provided insight and understanding, as well as promising clinical tools, to help identify needle-to-nerve contact and potentially hazardous intraneural injection. This narrative review describes and summarizes the contemporary animal studies primarily relating to indicators of needle-to-nerve contact and intraneural injection.(More)
BACKGROUND AND OBJECTIVES Although the stellate ganglion is located anteriorly to the first rib, anesthetic block is routinely performed at the C6 level. Ultrasonography allegedly improves accuracy of needle placement and spread of injectate. The technique is relatively new, and the optimal approach has not been determined. Moreover, the location of the(More)
In this double-blind, randomized, placebo-controlled study, we evaluated the efficacy and safety of different doses of prophylactic IV dexamethasone for postoperative nausea and vomiting (PONV) in 168 children (aged 2-15 yr) scheduled for strabismus surgery. Patients received IV dexamethasone 0.25 mg/kg (D 0.25), 0.5 mg/kg (D 0.5), 1.0 mg/kg (D 1), or(More)
We studied the efficacy of a range of doses of dexamethasone for prevention of postoperative nausea and vomiting following strabismus repair in children in a hospital-based, prospective, double-blinded, randomized, placebo-controlled trial. Two hundred and ten children were randomized to receive either dexamethasone in one of four dosages: 50 microg/kg(More)
Monitoring the injured brain is an integral part of the management of severely brain injured patients in intensive care. Brain-specific monitoring techniques enable focused assessment of secondary insults to the brain and may help the intensivist in making appropriate interventions guided by the various monitoring techniques, thereby reducing secondary(More)
