Aim: To find the frequency of CSF leakage after primary repair incidental durotomy in lumbar spine surgery with use fibrin glue. Study Design: Descriptive case series. Place and duration study: Neurosurgery Unit 2, Punjab Institute Neurosciences, Lahore General Hospital, from 25-02-2021 to 25-08-2021. Methodology: Sixty five patients admitted for informed written consent was taken. All cases we...

The effort that occurs during the Valsalva maneuver provokes a raise in intracranial pressure and may decompensate patients with increased intracranial pressure. The aims of this study were to evaluate the incidence of intestinal constipation in the preoperative period of patients with intracranial tumors and establish a relationship between constipation and intracranial pressure decompensation...

BACKGROUND In the presence of elevated cardiac filling pressures, the decline of blood pressure (BP) during the straining phase of a Valsalva manoeuvre is blunted or absent. We compared the use of non-invasively measured BP response to a Valsalva manoeuvre with clinical assessment and bioimpedance measurements to identify haemodialysis patients at risk of acute congestive heart failure (CHF). ...

AIM To assess the correlation between retrograde leak point pressure (RLPP) and 24-hr pad weight (24PW) in men with post-prostatectomy incontinence. METHODS We performed RLPP and 24PW measurements on 61 patients with a history of post-prostatectomy stress urinary incontinence (SUI). We examined the relationship of RLPP and 24PW. We also reviewed the urodynamic and clinical data of these patie...

In The Lancet, Andrew Appelboam and colleagues present the fi ndings of a simple but clinically relevant investigation of a safe and non-invasive treatment for patients with stable supraventricular tachycardia who present to emergency departments. This topic is important because patients with supraventricular tachycardia are common, often recurrent, emergency department attenders, and can requi...

Small leaks in the low-pressure system (LPS) of the anesthesia gas machine can cause hypoxia or patient awareness. We sought to determine the relative sensitivities of the various tests recommended for detecting LPS leaks before anesthesia. Special adapters were fashioned to create leaks of six different sizes in the LPS that were equivalent to the following: a single 25-, 22-, 20-, or 15-gauge...

The pudendal nerve innervates the external urethral sphincter and, when injured, can contribute to incontinence development. This experiment was designed to study the time course of functional changes in the urethra after pudendal nerve crush in rats. Leak-point pressure (LPP) was measured 2, 4, 7, or 14 days after bilateral pudendal nerve crush and was compared to that of a control group. LPP ...

The LMA Supreme is a new extraglottic airway device which brings together features of the LMA ProSeal, Fastrach and Unique. We test the hypothesis that ease of insertion, oropharyngeal leak pressure, fibreoptic position and ease of gastric tube placement differ between the LMA ProSeal and the LMA Supreme in paralysed anesthetised patients. Ninety-three females aged 19-71 years were studied. Bot...
