أجريت الدراسة في قسم التخدير و الإنعاش في مشفى الأسد الجامعي في عام 2012 - 2013 و شملت 200 مريضاً تراوحت أعمارهم بين 12 - 65 عاماً أجريت لهم عمليات جراحية متنوعة مثل: عظمية و جراحة عامة و جراحة نسائية و جراحة بولية. قسم المرضى إلى مجموعتين: الأولى: خضع المرضى فيها للبروبوفول حيث تم استخدامه في المباشرة الوريدية و في الاستمرارية تم استخدام الغاز الإنشاقي السيفوفلوران بالتركيز السنخي الأصغري MAC المناسب لكل مريض. الثانية: استخدم فيها التيوبنتال البروبوفول للمباشرة و كانت الاستمرارية باستخدام الغاز الإنشاقي السيفوفلوران بالتركيز السنخي الأصغري MAC الأقل من القيم المطلوبة. هدفت الدراسة إلى دراسة أهمية قيمة التركيز السنخي الأصغري MAC من أجل الوقاية من عودة الوعي أثناء التخدير العام و الحفاظ على عمق تخديري يتناسب و شدة العمل الجراحي مع مراعاة خصوصية كل مريض. أما نتيجة الدراسة فكانت: أن نسبة حدوث الصحو أو عودة الوعي، أو تذكر أحداث أثناء العمل الجراحي في المجموعة الأولى كانت أقل مما هي في المجموعة الثانية. و الخلاصة: أن التقيد بقيم التركيز السنخي الأصغري MAC الخاص بالغاز الإنشاقي المستخدم و (الذي كان السيفوفلوران) في بحثنا، استطاع أن يقي من اختلاط الصحو، أو عودة الوعي أثناء العمل الجراحي.
This study was carried out in the Department of Anesthesia and Reanimation at AL-Assad University Hospital Lattakia Syria during the year 2012-2013 the study included 200 patients between 12 and 65 years old the most common surgical procedures they had were general surgery, urinary surgery, orthopedic surgery, genecology surgery. Patients were divided into two groups: for the first group: Propofol was used for induction and an inhaling gas with a suitable minimum alveolar concentration MAC was used for maintenance the gas used was Sevoflurane. For the second group: Thiopental or Propofol was used for induction and Sevoflurane for maintenance with MAC less than the suitable concentration. The aim of the study was to show the importance of Minimum Alveolar Concentration and keep a deep anesthesia in order to prevent awareness and recall. The result was better in the first group because the percentage of awareness and recall was less than in the second group. The study shows that the use of inhaling anesthesia is well, but the Minimum Alveolar Concentration MAC (Sevoflurane is the studied gas) must be controlled.

The purposes of the present study were to determine the
effectiveness of infiltration anesthesia in the mandibular
primary molars compared with inferior alveolar nerve block,
and how tooth location, and the type of treatment performed,
and the vo
lume of anesthetic solution relate to the quality of
anesthesia.
The study population consisted of ١١٦ cooperative
children, ٣-٦ years old, requiring the same type of treatment
on contralateral mandibular molars.
Uterine curettage is considered the fundamental procedure in the treatment of
abortions especially in complete and missed abortions in many counties despite the availability of many alternative methods to treat these cases. It is also widely used as
a diagnostic means to diagnoses the endometrial abnormalities which cause abnormal uterine bleeding. This research aims to figure out complications rate which occur during uterine curettage and the subsequent complications rate and to identify the most important causes of them for the purpose of knowing the efficiency and the safety of the diagnostic and therapeutic uterine curettage.
Mankind is still suffering from many diseases , and with the
development of civilization there are many diseases that appear with
different clinical types , but tumors, especially malignant , are still very
important.
Cervical cancer is the secon
d common cancer in women , as it is the cause of
more than 200.000 deaths annually. Hence the importance of early detection
of cervical cancer and of decreasing mortality.
Pregnancy and childbirth are two instinctive actions that a woman's reproductive system performs in order to produce a new organism that completes the continuity of life, and childbirth is the outcome of pregnancy for several months, and it is suppos
ed to be as calm and safe as possible for both mother and child, and birth pains differ from mother to mother and even from birth To another, it is very special and depends on several factors, including: the mother's ability to withstand pain, the size and position of the fetus, and the strength of uterine contractions during childbirth. Since ancient history, various ideas and methods have appeared to overcome the pain of childbirth in which there was a lot of sorcery and a little logic, but With the development of science and deepening into the depths of the human psyche, the idea of childbirth without pain began to develop, and it became based on scientific foundations, especially after the rapid development in the field of obstetric anesthesia and the numerous studies in the field of local anesthesia and epidural anesthesia, where this method changed all the parameters of childbirth without pain to become a realistic reality Women touch it daily in maternity homes scattered all over the world while maintaining complete alertness without fear, anxiety or pain, and actively participating in full vigilance and vigilance in the status of their newborn while he is fully active and effective and without little discouragement, and Peridural analgesia is considered one of the best types of analgesia and anesthesia used to accomplish childbirth and cesarean section, and it has received many international studies.
This study was conducted to investigate the relationship between estrogen
depletion ,calcium-deficiency,and alveolar bone loss.
Alveolar bone loss was evaluated by radiographic and visual inspection of
rabbits with experimental lack of estrogen an
d calcium.
Twenty female local rabbits (4 months old) were divided into four groups
:group a -ovariectomized and given a standard solid diet.
Group b-ovariectomized and given a calcium – deficient diet
Group c-sham-ovariectomized and given a standard solid diet.
And group d-sham-ovariectomized and given a calcium-deficient diet
after 8 weeks,the rabbits were sacrificed .
The maxillae, mandibles, femurs, and tibias were removed carfully and
fixed in 10% neutral buffered formalin. The bone mineral density of each
bone and the alveolar bone loss were measured.the bone meniral densities of
the maxillae,mandibles,femurs and tabias in group (c) were significantly
higher than those in groups (b)and (d),but not higher than those in group
a.however there were no significant differences between any of the groups
with regard to alveolar bone loss from the cemento-enamel junction to the
molar bone crest.
