This search included 150 pregnant women who had gestational age of 36 weeks or more, and had been admitted to the Department of Obstetrics and Gynecology at Al – Assad University Hospital in Lattakia for the spontaneous vaginal delivery during the study period ( 1\1\2012 to 1\7\ 2013). Exclusion criteria were patients undergoing cesarean section, patients with placenta previa, or abruptio placenta, patients with hemoglobin<9 gm%, pregnancy-induced hypertension or pre eclampsia–eclampsia, grand multiparty, coagulation abnormalities, positive history of PPH, expensive hemorrhage or other medical disorders. Patients were randomly divided into three groups: ( 1: uterine massage group, 2: 10 units oxytocin in 500 cc glucose 5% intravenously with delivery of the anterior sholder\ control group, 3: three 200µg rectal misoprostol tablets\study group). No significant differences were observed between the groups regarding baseline characteristics. There was blood loss of ≥500 ml occurred in 18% in the first group, 6% in the second group, 8% in the third group. Routine use of 600 µg of rectal misoprostol was effective in reducing blood loss after delivery ل gm%, pregnancyts with hemoglobin}ergoing cesarean section, patients with placenta pre and g (RR 0.44 ; CI 0.32 – 1.53), but not as effective as intravenous oxytocin (RR 1.33 ; CI 0.4 – 3.39). Although these were differences, they were not significant (No significant differences were observed between the control and study groups for the length of the third stage of labor, the estimated blood loss, the changes in Hb and Hct concentrations, need for additional uterotonics, manual removal of placenta, blood transfusion…..). This dose of misoprostol and route of administration were well tolerated, and usual side effects such as shivering and fever were transient, resolved on their own, and were not threatening. Because PPH is the most significant direct cause of maternal mortality and because most of these maternal mortality occurs in low resource countries, misoprostol offers several advantages over oxytocin in such settings. It is formulated as a tablet, widely available and affordable, and it does not need require special storage conditions (i.e. it is stable at ambient room temperature and does not require specific conditions for transfer and has a shelf-life of several years). It also does not require any special skills, equipment, or facilities for its use. So misoprostol can fill a service delivery gap in settings where women and providers are unable to access oxytocin.ل gm%, pregnancyts with hemoglobin}ergoing cesarean section, patients with placenta pre and g

Research summary
تتناول هذه الدراسة مقارنة بين تأثير الأوكسي توسين والميزوبروستول في الوقاية من نزوف الخلاص (PPH) بين 150 سيدة حامل في مشفى الأسد الجامعي باللاذقية. تم تقسيم المشاركات إلى ثلاث مجموعات: مجموعة تمسيد الرحم، مجموعة الأوكسي توسين، ومجموعة الميزوبروستول. أظهرت النتائج أن استخدام 600 مكغ من الميزوبروستول كان فعالاً في تقليل خسارة الدم بعد الولادة، لكنه لم يكن بنفس فعالية الأوكسي توسين. لم تكن هناك فروقات إحصائية كبيرة بين المجموعات من حيث طول المرحلة الثالثة من المخاض، خسارة الدم المقدرة، التغيرات في تركيز الهيموغلوبين والهيماتوكريت، الحاجة لمقبضات رحم إضافية، أو الحاجة لاستخلاص المشيمة يدويًا. كانت الآثار الجانبية للميزوبروستول مثل الحمى والعرواءات عابرة وغير مهددة للحياة. توصي الدراسة باستخدام الميزوبروستول في الأماكن منخفضة الموارد حيث يتفوق على الأوكسي توسين من حيث التكلفة والتوافر وسهولة الاستخدام.
Critical review
دراسة نقدية: على الرغم من أن الدراسة تقدم معلومات قيمة حول فعالية الميزوبروستول في الوقاية من نزوف الخلاص، إلا أن هناك بعض النقاط التي يمكن تحسينها. أولاً، كان من الممكن أن تشمل الدراسة عددًا أكبر من المشاركات لزيادة قوة النتائج. ثانياً، لم يتم التطرق بشكل كافٍ إلى الآثار الجانبية الطويلة الأمد لاستخدام الميزوبروستول. ثالثاً، كان من الممكن أن تكون هناك مقارنة بين طرق إعطاء الميزوبروستول المختلفة (فموي، تحت اللسان، شرجي) لتحديد الطريقة الأكثر فعالية وأقل آثارًا جانبية. وأخيراً، كان من الممكن أن تشمل الدراسة تحليلًا اقتصاديًا لتكلفة استخدام كل من الأوكسي توسين والميزوبروستول في الأماكن منخفضة الموارد.
Questions related to the research
  1. ما هي الفروقات الرئيسية بين الأوكسي توسين والميزوبروستول في الوقاية من نزوف الخلاص؟

    الأوكسي توسين كان أكثر فعالية في تقليل خسارة الدم بعد الولادة مقارنة بالميزوبروستول، لكن الفرق لم يكن ذا أهمية إحصائية كبيرة. الميزوبروستول كان فعالًا أيضًا ولكنه لم يكن بنفس فعالية الأوكسي توسين.

  2. ما هي الآثار الجانبية لاستخدام الميزوبروستول؟

    الآثار الجانبية للميزوبروستول تضمنت الحمى والعرواءات، لكنها كانت عابرة وغير مهددة للحياة. كما تم تسجيل بعض الحالات من الغثيان والإقياء والإسهال، لكنها انتهت لوحدها في غضون بضع ساعات.

  3. لماذا يعتبر الميزوبروستول خيارًا جيدًا في الأماكن منخفضة الموارد؟

    الميزوبروستول متوفر على شكل أقراص، ميسور التكلفة، لا يحتاج لتخزين خاص، ثابت في حرارة الغرفة، وله عمر تخزين طويل. كما أنه لا يحتاج إلى مهارات أو معدات خاصة لاستخدامه، مما يجعله مناسبًا للأماكن منخفضة الموارد.

  4. ما هي التوصيات الرئيسية للدراسة؟

    توصي الدراسة باستخدام الميزوبروستول بجرعة 600 مكغ شرجيًا في الوقاية من نزوف الخلاص، خاصة في الأماكن التي لا يتوفر فيها الأوكسي توسين. كما توصي بتحسين معرفة وقدرات المولدين على الوقاية من نزوف الخلاص والمراقبة الحثيثة للولادات.

The study covered 30 cases of patellar fractures in persons who were accepted and treated surgically at Al-Assad University Hospital in Lattakia from 2008 to 2013.Ages of patients ranged between 16-70 years. Average load of clinical and radial conti nuation was six months. The smaller age of traumatism amounted 16 years and larger age 70 years; average load of age was 37.66 years. The number of traumatism in male was amounted 12 and female 18. In estimating the results, we depend on Lysholm scale scoring. Functional results were studied after 6 months and we had excellent result in 27% of cases and good results in 47% of other cases
This research was conducted to study all the causes leading to postpartum hemorrhage in order to implement all the appropriate treatments, according to all reason and thus avoiding the complications of postpartum hemorrhage and death, and study of th e risk of bleeding factors in order to reach the best method of prevention of bleeding . This research included on 77 patient acceptable in Al Assad University Hospital in Lattakia, with primary postpartum hemorrhage occurred after vaginal delivery, including (12) patient after vaginal birth outside the hospital, during the extended study period: from 1/1/2014 until 1/1 / 2016, and excluded all patients who were born cesarean delivery. We determine the percentage of postpartum hemorrhage occurring between vaginal deliveries in the hospital, and the ratio was (3.52%), and we could not determine this percentage outside the hospital.
This study was organized to find out the role and the efficacy of Misoprostol in treating postpartum hemorrhage unresponsive to traditional agents that contract the uterus . Place : Maternity hospital at Faculty of Medicine in Damascus university Time : from 2, January, 2004 to 2, January, 2005 . Number of patients : 18 patients who met the criteria in that period of time . Criteria of selection : any patient with post partum hemorrhage due to uterine atony that did not respond well to the administration of Oxytocin and Metergin . Misoprostol is an effective treatment of post partum hemorrhage due to uterine atony unresponsive to Oxytocin and Metergin. Our study confirms the results of international studies of effectiveness of the use of misoprostol in treating post partum hemorrhage due to uterine atony.
The bleeding after delivery (Postpartum Hemorrhage-PPH) is the most important complications that occur after a natural or cesarean delivery, and represents about a quarter of maternal mortality around the world. Midwives play a basis role in preventi on of bleeding after birth. So This research aims to evaluate the knowledge of midwives about using strategies to prevention and management the bleeding after delivery. Its sample included all midwives in obstetrics departments in Alasad University, Children and Obstetric, and Tishreen University Hospital all in Lattakia city. Data were collected using a questionnaire developed by researcher. The results according to strategies used in prevention and management of bleeding after delivery showed that 60% of the level of knowledge of midwives were "inappropriate". There were significant inverse relationship (P = 0.006) between ages of midwives and level of knowledge. Also showed a significant inverse relationship between number of years of experience with the midwives and level of knowledge (P = 0.01). So we suggest conducting training sessions and educational lectures for midwives with respect to the strategies used in prevention and management of bleeding after delivery, and must evaluate the midwives information about prevention and management of bleeding after delivery periodically and continuously.
Research was conducted on a sample of 45 patients in the Department of hemodialysis in Alssad University Hospital in Latakia, It was implemented two policies nursing care included each policy applied on two experimental groups I and II for a period o f 3 months, and the patients were monitored patients using the form author 3 parts of a demographic data and the activities of nursing care and monitoring the occurrence of complications.
