This article aims to present a concise overview regarding global economic ideas and its historical development with brief evaluation of capitalism and communism as well as question of laissez-faire and concept of ownership in relation to Islamic economic thought. What are the rudiments, fundamentals and historical sketch of these systems? Measuring them analytically vis-à-vis their comparative examination has been taken into account to visit the characteristics of prevailing as well as outdated and nonoperational economic systems. As capitalism emphasis on eagerness to find wealth where billionaires are about to getting more and more ignoring various other ethical perspectives and paying no attention to the poor classes of society. Communism claiming equality remained also not compatible to sustain around the globe as a balanced and stable system. At the end this article predicts that other than Islamic economic thought no system may fulfill the natural need of global economy and it also recommends that Islamic Scholars have to present an alternative full-fledged practical model for economics.

A Randomized Control Trial Comparing Train of Four Ratio ≥0. 9 to Clinical Assessment of Return of Neuromuscular Function Before Endotracheal Extubation on Critical Respiratory Events in Adult Patients Undergoing Elective Surgery at the Aga Khan University Hospital, Nairobi

Background: There is increasing evidence that the incidence of postoperative residual paresis after using neuromuscular blockers ranges from 24 to 50% in post anaesthesia care unit and is associated with postoperative complications such as critical respiratory events as evidenced by hypoxia, hypoventilation and upper airway obstruction. Quantitative neuromuscular monitoring (such as the assessment of Train of four (TOF) ratio) and reversal of neuromuscular blockers has been shown to reduce postoperative residual paresis. There are very few outcome studies on effect of residual paresis in Post anaesthesia care unit (PACU). There are no published randomised control trials investigating whether using a TOF ratio ≥0.9 before endotracheal extubation compared to clinical assessment of return of neuromuscular function reduces the incidence of critical respiratory events in PACU. Primary Objective: To determine whether using TOF ratio ≥0.9 compared to clinical assessment of return of neuromuscular function before endotracheal extubation reduces the incidence of critical respiratory events in PACU Secondary objectives: To determine incidence and severity of hypoxia in PACU. To determine incidence of upper airway obstruction in PACU Study Design: Randomised, prospective, double blinded control trial Setting: Operating theatres of the Aga Khan University hospital Nairobi Population: Adults, aged 18-65 years ASA physical status I and II undergoing elective surgery under general anaesthesia. Sample size: 168 patients randomised to TOF ratio group and clinical assessment group, 84 per group. Methods: Patients requiring general anaesthesia for elective surgery with cisatracurium as the muscle relaxant were randomised into 2 groups using computer generated numbers. Group 1 were patients who required a TOF ratio of ≥0.9 before extubation. Group 2 patients were extubated based on clinical assessment of return of adequate neuromuscular function by the anaesthetist as is the standard of practice at the Aga Khan University hospital Nairobi. General anaesthesia was standardised in both groups. Both the investigators and patients were blinded during the study. Once the patient was transferred to PACU, oxygen saturation (SP02), respiratory rate and any signs of upper airway obstruction as demonstrated by stridor, laryngospasms or requirement of any airway manipulation was recorded for the first 30 minutes. Duration of anaesthesia and surgery was also recorded. Patient demographics were recorded and analysed. vii Results: There was no statistical difference between the 2 groups in terms of patient demographics, duration of surgery and anaesthesia and duration since last muscle relaxant was given. In terms of hypoxia on arrival in PACU, the incidence of
