Abstract

ABSTRACT:BACKGROUND:The nature and indications for thyroid surgery vary and a perceived risk of postoperative complications such as seroma , haematoma , wound infection and haemorrhage post-surgery is one reason why wound drains are frequently inserted. They are generally used as a matter of the surgeon’s habit or preference more than a matter of proven benefit in the patient’s postoperative period.OBJECTIVE:To evaluate the differences in outcome and complications following thyroid surgery whether draining the wound or not .PATIENTS AND METHODS:One hundred forty five patients with different thyroid diseases requiring surgical intervention presenting to the first surgical unit in Baghdad teaching hospital between the first of October 2007 to the 31th of December 2009(27 months period) were enrolled. Patients were divided into two groups : those who had their wounds drained postoperatively ; (the drain group DG) and those who had their wounds closed without drain ; (the non drain group NG).RESULTS:Seroma occurred in three patients (3%) in the DG, and in two patients (4.4%) in the NG. Small haematoma occurred in three patients (3%) in the DG, and in two patients (4.4%) in the NG. Large haematoma occurred only in one patients (1%) in the DG, and it didn't occur in the NG. Wound infection occurs only in two patients (2%) in the DG, and in one patient (2.2%) in the NG. The mean of in-hospital stay was 2.07 days in the DG, and 1.06 days in the NG.CONCLUSION:The use of drain showed no effect on the prevention of wound infection , seroma , haematoma formation or the need for re-exploration, indeed the use of drain had lengthened the in hospital stay .So the Routine use of drains after thyroid surgery might be therefore not necessary, if not detrimental.

Abstract

COMPARISON BETWEEN SINGLE DRAIN VERSUS TWO DRAINS IN THE PREVENTION OF POSTMASTECTOMY SEROMA Ahmed N Abdulnabi MB,ChB, CABS, Specialist Surgeon, Al-Fayhaa General Hospital, Basrah, IRAQ. Abstract Breast cancer is managed with many surgical options. Modified radical mastectomy with axillary dissection is the commonest procedure done nowadays. It is not free from complications, where seroma one of these. A comparative study was conducted to evaluate the effectiveness of single delayed removed drain versus two drains early removed for the prevention of seroma formation. One hundred and fifty patients were treated by modified radical mastectomy with axillary dissection for breast cancer between January 2010 and September 2016 in Al-Fayhaa General Hospital. Patients were divided into two groups, fifty patients were managed with single drain left for nine to ten days and the other one hundred patients had two drains removed after five days for prevention of seroma formation under mastectomy flaps. The highest age group affected by breast cancer was the 36-45 years and the lowest one was the 25-35 years. The incidence of seroma was 12% for the first group and 30% for the second one. The wound infection slightly more in the first group (14%) when compared with the other group (12%). In conclusion, the use of single drain for slightly longer time is better than two drains removed early in the prevention of seroma formation.

Abstract

This study is concerned with investigating the advantages of using prefabricated vertical drains (PVD) to improve the foundation soft soil under an embankment. PVD combined with staged construction of embankment is considered as a common technique to reduce both the time for full consolidation and the excess pore water pressure. Rocscience Settle 3D software was used to analyze the embankment and the underlying soft soil which is chosen to be at Basra region. The numerical analysis showed that the PVD is very effective in accelerating the consolidation process and increasing the long term stability of the embankment. It is interesting to note that installing the PVD with spacing (1 m) leads to a rapid dissipation of most of the excess pore water pressure at the end of each stage. The length of PVD sheets can significantly accelerate the consolidation more than the spacing.

تعنى هذه الدراسة بالتحقيق في مزايا استخدام المبازل الشاقولية مسبقة الصنع (PVD) لتحسين تربة الأساس الضعيفة تحت التعلية الترابية. يعتبر إستخدام PVD جنبا إلى جنب مع البناء على مراحل للتعلية الترابية أسلوبا" شائعا" لتقليل الوقت لكل من الإنضمام وضغط المياه المسامي الزائد. تم استخدام برنامج (Rocscience Settle 3D) لتحليل التعلية والتربة الضعيفة الأساسية والتي تم اختيارها لتكون في منطقة البصرة. أظهر التحليل العددي أن PVD فعال جدا في تسريع عملية الإنضمام وزيادة الاستقرار طويل الأمد للتعلية الترابية. ومن المثير للاهتمام أن نلاحظ أن تثبيت PVD مع تباعد (1 م) يؤدي إلى التبديد السريع لمعظم ضغط المياه المسامي الزائد في نهاية كل مرحلة. طول شرائح PVD يمكن أن يسرع بشكل كبير من اللإنضمام أكثر من التباعد فيما بينها.

Abstract

the influence of permeability tensor upon drainage of anisotropic soils under ponded water and steady recharge (rainfall) is theoretically investigated. Tensorial permeability has led to the formulation of mixed type partial differential equations. Since there is no analytical solution to this problem, the formulation is therefore solved numerically by the method of finite elements. The finite element formulation is implemented into a computer model which can be applied to any problem of seepage under steady state conditions. Two different example problems representing two different flow conditions under full anisotropy have been studied. Results of the model for the isotropic case were checked against exact mathematical solutions derived analytically for isotropic soils and found to be accurate which indicates that using this model for anisotropic soils is safe and sound.
