Abstract

Abstract This retrospective study aimed to determine the main indications of tracheostomy in four main hospitals in Basrah centre. The study included 89 patients who were submitted to tracheostomy during a 2 year period and data was reviewed from the medical records. Patients were 70 males (78.66%) and 19 females (21.34%). The age of the patients ranged from 1-75 years with mean age of 44.367±13.18 years. Open surgical tracheostomy was performed in all patients, 89.89% of them were submitted to surgery as elective procedure and 94.39% were operated upon under general anesthesia. The main indications of tracheostomy in this study is the need for prolonged ventilation (61.80%) mostly caused by head injury, followed by upper aero-digestive tumor (19.1%) and lastly cranio-cervical trauma (8.89%). In conclusion, the commonest indication of tracheostomy in Basrah is the need for prolonged ventilation.

Abstract

Summary:Background: Acute inflammatory demylinating polyneuropathy (Guillain-Barr'e syndrome) is the commonest cause of acute neuromuscular paralysis in most countries. The onset of symptoms in patients with GBS can either be acute or sub acute .Ventilatory failure is primarily caused by inspiratory muscles weakness although weakness of abdominal and accessory muscles of respiration, retained airway secretion leading to aspiration and atelectasis are all contributing factors. Nutritional support of critically sick children is important for metabolic maintenance and tissue repair.Methods: To identify clinical and respiratory features associated with progression to respiratory failure in children with GBS. Twenty two consecutive children with severe (Rapidly progressive) GBS admitted to the RICU in Children Welfare Teaching Hospital-Medical City –Baghdad, between July 2004-July 2006, were studied .Other 22 children with sub acute GBS who didn't receive mechanical ventilation admitted in the same period to the same hospital as a control group.Results: There is significant association between each of bulbar, autonomic neuropathies and low SiO2 at admission with severe GBS .There is significant reduction in duration of mechanical ventilation and duration of RICU stay achieved by the use of Freamine amninoacid solution as partial parenteral nutrition.Conclusion: Progression to mechanical ventilation was highly likely to occur in those patients with rapid disease progress (less than one week) bulbar dysfunction and dysautonomia, and low SiO2 at admission. Partial parenteral nutrition may reduce the duration of mechanical ventilation and RICU stay by about 3 days.Keywords: GBS; mechanical ventilation; children.

Abstract

Computational Fluid Dynamics (CFD) of indoor environment as well as quality considerations are important element in the study of energy consumption, thermal comfort and indoor air quality in buildings. This paper investigate a comparison work between impinging jet, displacement, and mixing ventilation systems for an isothermal and non-isothermal ventilated room for Indoor Air Quality (IAQ) and thermal human comfort under Iraqi climate. For IJV system, draught discomfort is the issue of most concern since it supplies cooled air directly to the occupied zone. This study investigated a number of factors influencing draught discomfort and temperature stratification in an office environment. The considered factors, supply airflow rate and supply air temperature. RNG K-Ɛ turbulence model was used with the turbulent flow. The second aspect included numerical analyses by adopting ANSYS FLUENT15 code to generate simulation models. A square shaped air supply device was used with [0.1 times room height (h)] outlet terminal height from the foot level end. The IJV system proved more efficient than displacement and mixing ventilation systems. The Air Distribution Performance Index (ADPI) obtained for an isothermal and non-isothermal ventilated room adopting IJV system gave best values (0.80, 0.83) respectively compared with the other two ventilation systems.

CIPROFLOXACIN OTIC DROPS FOR PREVENTION OF OTORRHOEA FOLLOWING MYRINGOTOMY AND VENTILATION TUBE INSERTION AMONG CHILDRENAmmar A Selman*, Ahmed A Alansary# & Abdulwahab B Abdulwahab@*MB,ChB, Arab board candidate, ENT Dept., Basrah General Hospital. #MB,ChB, FICMS, Consultant Otolaryngologist, Head-ENT Dept, Basrah General Hospital. @MB,ChB, FICMS, ENT Specialist, ENT Dept, Basrah General Hospital.Abstract This study aimed to determine the effect of topical otic drops on the rates of postoperative ventilation tube otorrhoea and ventilation tube occlusion in children after myringotomy and ventilation tube insertion in children. A randomized comparative interventional study was carried out on 45 children (84 years) attending Basrah General Hospital, they were 32 males (71%) and 13 females (28.9%), 39 cases have bilateral otitis media with effusion and 6 with unilateral disease, the age range was 3-17 years old. After full assessment of patients, myringotomy and ventilation tube insertion was done for every one with or without adenoidectomy and tonsillectomy or both. They were divided into three groups: first group with no local intervention, second group with single application of ciprofloxacin otic drops at surgery, third group with continuous application of ciprofloxacin otic drops for four days after surgery. A follow-up visit was instructed after 14 days for all. The rates of postoperative ventilation tube otorrhoea and ventilation tube occlusion were recorded. With application of statistical analysis on the results, there was a statistically significant reduction in the rate of postoperative otorrhoea with using the ciprofloxacin otic drops for four days after surgery (P-value 0.043) with a reduction in the incidence of otorrhoea from 29.6% to 7.6% as compared to the group without using the drops. No significant results obtained with a single drops application at time of surgery. There were no statistically significant results in regard to the rates of postoperative ventilation tube occlusion among the study groups. In conclusion, ciprofloxacin otic drops application for few days after myringotomy and ventilation tube insertion appears to be effective to reduce the rate of postoperative ventilation tube otorrhoea. Neither the single nor the continuous otic drops applications could reduce the rates of postoperative ventilation tube occlusion

Abstract

ABSTRACT:BACKGROUND: Intubation and mechanical ventilation are sometimes necessary during treatment of acute stroke. Indications include neurological deterioration, pulmonary complications, and elective intubation for procedures and surgery.OBJECTIVE: This study was performed at neurosciences hospital for the period 2013 - 2014 to prospectively assess the prognosis of stroke patients who require ventilation in a neurological intensive care unit and to determine factors that may influence outcome. METHODS: Analysis was made of 124 consecutive stroke patients,who required mechanical ventilation over a 2-year period. We determined the survival rate at 1 year after admission.RESULTS: The 1-year survival rate was 33.1%. Sixty-five patients (52%) died in the neurological intensive care unit. Among 17 variables analyzed, seven were found to significantly influence 2-month fatality in the univariate analysis: age greater than 65 years, atrial fibrillation, bilateral absence of pupillary light reflex, bilateral absence of corneal reflex, bilateral Babinski’s sign, infratentorial stroke, and Glasgow Coma Scale (GCS) score less than 10. Independent predictors of death at 2 months were age greater than 65 years, GCS score less than 10, and intubation performed because of coma or acute respiratory failure.CONCLUSION:Intubation and mechanical ventilation of severe stroke patients should be performed in a timely manner.older patients comatose on admission requiring mechanical ventilation have very poor prognosis. Fatality rate in our patients was high, but one third were still alive at 1 year after admission. Patients electively intubated in our study had a better prognosis independent from other factors, including age and GCS score.The probability of death at 2 months was more than 2.5 times greater in patients who were intubated because of neurological or respiratory deterioration than in those electively intubated for angiography or surgical intervention.

Abstract

Applications of nonlinear, time variant, and variable parameters represent a big challenge in a conventional control systems, the control strategy of the fuzzy systems may be represents a simple, a robust and an intelligent solution for such applications. This paper presents a design of fuzzy control system that consists of three sub controllers; a fuzzy temperature controller (FC_T), a fuzzy humidity controller (FC_H) and a ventilation control system; to control the complicate environment of the greenhouse (GH) using a proposed multi-choice control system approach. However, to reduce the cost of the crop production in the GH, the first choice is using the ventilation system to control the temperature and humidity of the GH environment according to the external climate if it is possible, if it is not possible then the second choice uses the FC_T to actuate the cooling-heating system to control the temperature and FC_H to actuate the humidifier-dehumidifier to control the humidity of the GH environment. The resultant is a robust, multi choice and multi-mode capability system. The designed system reflects the fuzzy system capability to deal with complicated environments and its flexibility to use the same design in controlling different applications

التطبيقات ذات البارامترات المتغيرة, اللاخطية والمتغيرة مع الوقت تمثل تحدي كبير بالنسبة الى انظمة السيطرة التقليدية. ان هذا التحدي ربما يكون اكثر تعقيدا عند استخدامه للسيطرة على الانظمة عبر شبكات الاتصال السلكية او اللاسلكية. من جهة اخرى فان ستراتيجية السيطرة في الانظمة الضبابية ربما تكون حلول بسيطة, متينة وذكية لمثل هذه التطبيقات.في هذا البحث سيتم تصميم نظام سيطرة ضبابي يتكون من ثلاث مسيطرات: مسيطر ضبابي حراري, مسيطر ضبابي للرطوبة ونظام سيطرة على التهوية, للسيطرة على البيئة المعقدة للبيت الزجاجي باستخدام نظام سيطرة مقترح متعدد الاختيارات. على اية حال, لتقليل كلفة انتاج المحاصيل في البيوت الزجاجية, فان اول اختيار يتمثل في استخدام نظام التهوية للسيطرة على حرارة ورطوبة البيت الزجاجي بالاعتماد على المناخ الخارجي اذا كان ممكن. واذا لم يكن ممكن, فان الاختيار الثاني يستعمل المسيطر الضبابي الحراري لتشغيل نظام التدفئة-التبريد للسيطرة على درجة الحرارة والمسيطر الضبابي للرطوبة لتشغيل نظام الترطيب-التجفيف للسيطرة على الرطوبة. ان النتيجة التي تم الحصول عليها هي نظام متين, متعدد الاختيارات والانماط في السيطرة. ان هذا النظام في تصميمه يعكس قابلية النظام الضبابي في التعامل مع البيئات المعقدة ومرونته في استخدام نفس التصميم لعدة تطبيقات.

Abstract

Background:Guillain Barré syndrome (GBS) is an acute post infective autoimmune polyradiculo-neuropathy; it is the commonest polyneuropathy causing respiratory failure. A lot of studies suggested certain GBS clinical and preclinical features anticipate and predicate the neuromuscular respiratory failure and can accurately assess the progression to mechanical ventilation; bulbar muscles involvement, severity of weakness of upper and lower limbs, bilateral facial muscles involvement and autonomic nervous system involvement were the main features associated with progression to mechanical ventilation.Objectives:To assess demographic, clinical and para clinical features and their relation with the progression of GBS to respiratory failure.Methods:Clinical and paraclinical predictors of impending respiratory involvement and requirement for mechanical ventilation were studied in 40 GBS patients aged 12-57 years (28 males and 12 females).Results:Ten (6 female/4 male) patients (25%) were admitted to the intensive care unit and received mechanical ventilation. Younger age, female gender and rapid disease progression in first 3 days were associated with respiratory involvement and subsequent ventilation. Bulbar weakness, bilateral facial palsy, poor digit counting (<10/1 breath) were the strongest indicators of impending respiratory failure. In combination they were found in 90% of ventilated patients. Dense weakness (power grade ≤2), weak neck flexion and axonal electromyography also showed significant risk for mechanical ventilation. Other parameters (autonomic dysfunction, antecedent gastrointestinal and respiratory illness, earlier upper limbs weakness and pain) showed no statistical significance in our studyConclusion:Respiratory failure in the course of GBS can to some extent, predicted depending on clinical information. Respiratory failure was associated with younger age, female gender, rapid progressive weakness, bulbar weakness. Facial weakness. Dense weakness, weak neck flexion, poor digit count and axonal neuropathy.Keywords:Guillain Barre syndrome, respiratory failure, bulbar weakness, mechanical ventilation.

Abstract

The experimental analysis includes a patient lying on an operation table, surgical staff members, and surgical lights above the patient. The cold clean air is supplied to the room through grilles from ceiling diffusers and exhausted through low side walls. The first aim of the experimental study is to investigate the validity of air distribution within operation room and the effect of using the air filtering on the air flow distribution. Different air distribution system to what exists in the optical operation room, is also investigated by locating the inlet at the upper part of a side wall, while the exhaust grilles were in the lower part of the opposite side. From this study, it was found that the temperature and relative humidity in the surgical zone are 21.3oC and 49.3% in the optical operation room. While, the values in the experimental operation room are 23.6oC and 45.3%. These values in both operation rooms are in the acceptable range of the surgical conditions as well as for the carbon dioxide. Therefore, it can be using the wall air supply system in the operation room with good conditions for the surgical work.
