Anaesthsia

BACKGROUND: The efficacy of i.v. or topical lidocaine as an anaesthesia adjunct in improving clinical outcomes in patients receiving gastrointestinal endoscopic procedures under propofol sedation remains unclear. METHODS: Electronic databases (MEDLINE, EMBASE, and Cochrane Library) were searched for RCTs comparing the clinical outcomes with or without lidocaine application (i.v. or topical) in patients receiving propofol for gastrointestinal endoscopic procedures from inception to 29 March 2021...

INTRODUCTION: Brachial plexus blocks are frequently practiced and safe mode of anaesthsia. Although minor complications may occur, major complications are a rarity. However, we report a rare case of prolonged supraclavicular brachial plexus block which required almost 4 months to recover without a perceivable cause. CASE PRESENTATION: A 22-year-old gentleman posted for open reduction and internal fixation of both forearm bones was administered an ultrasound-guided supraclavicular brachial plexus block...

INTRODUCTION: Traumatic posterior dislocation of the hip (TPDH) is considered an absolute orthopeadic emergency and the outcome of management and prognosis is time dependent. The optimum time within which reduction should be achieved to yield excellent result has remained an issue of considerable controversy. In this paper we evaluated the influence of interval between injury and reduction of dislocation on the choice and outcome of management of TPDH. METHOD: This is a five year prospective and multicenter study in North-central Nigeria...

This prospective study was carried out is 250 patients undergoing CABG. The aim of this study was to assess the effects of high thoracic epidural anaesthesia during CABG, along with modified general anaesthsia; facilitate early extubation and fast tracking post operatively; evaluate effect on post-operative analgesia and discuss difficulties in patient selection for high thoracic epidural catheterization. 250 patients undergoing CABG over a period of nine months were included in this study. Patients with age >64 yrs, weight < 50 kg, EF < 50%, redo surgery, recent MI, receiving aspirin or ticlopidine or heparin were excluded from the study...

Twenty three adult patients with ischaemic heart disease undergoing elective non-cardiac surgery were studied. Induction of anaesthesia was similar for each patient and included thiopentone (4-5 mg/kg), morphine (0.1 mg/kg) and vecuronium (0.1 mg/kg). Additional morphine and vecuronium were used when necessary. All these patients were maintained with either sevoflurane (n=11) or isoflurane (n=12). The inhaled anaesthetics were titrated to achieve adequate clinical 'depth of anaesthsia' and to maintain mean arterial pressure within 20% of the pre-induction values...

The local anaesthetic and haemodynamic parameters achieved by lidocaine with clonidine or epinephrine, administered for maxillary infiltration anaesthesia, were studied in 40 patients (American Society of Anesthesiologists, physical status 1) who underwent upper third molar surgery. All patients received 2 ml of 2% lidocaine with clonidine (15 microg/ml; n=20) or epinephrine (12.5 microg/ml; n=20) in a randomized, double-blind fashion. Vascular effects were evaluated on the isolated human infraorbital arteries...

The aim of this study was to compare recovery assessed with the Newman, deletion af a's and postbox tests after total intravenous anaesthsia for procedures lasting more than 90 min, with either propofol (PPF) or midazolam (MDZ), reversed or not by flumazenil (FMZ). Thirty patients scheduled for peripheral surgery were randomly allocated to 3 groups of 10, receiving by continuous infusion until the end of surgery either PPF (n = 10) or MDZ (n = 20) combined with alfentanil. FMZ was administered thereafter to 10 patients receiving MDZ until they opened their eyes on command or to a maximum dose of 1 mg...

In patients with an intracardiac shunt, the oxygen saturation of the mixed venous blood cannot be measured, but it must be estimated from the oxygen saturation in the superior and in the inferior vena cava. We have evaluated the results of patients who had definitively no shunt and who had been catheterized for other reasons. Based on statistical principles we developed formulas to calculate the oxygen saturation of the mixed venous blood. We examined three group of patients: a) Children up to 11 years catheterized during general anaesthesia (58 patients) b) Children up to 11 years catheterized after premedication but without general anaesthesia (53 patients) c) Adults catheterized without general anaesthsia (59 patients) We found that the formulas from the patients who had been catheterized during general anaesthesia were quite different from those without anaesthesia...
