Iron-dependent erythropoiesis in women with excessive menstrual blood losses and women with normal menses
2013
In women of fertile age, iron loss consequent to excessive menstrual discharge is by far the most frequent cause of iron-deficient anemia. However, the relationship between menstrual discharge and iron loss is poorly understood. In this prospective study, total menstrual and iron losses were assayed in a large cohort of non-anemic women and women with excessive menstrual blood losses (menorrhagia) in order to provide data useful for intervention. One hundred and five Caucasian women aged 20–45 years were recruited. Blood cell count and serum ferritin (SF) levels were determined in each case before menses. Menstrual fluid losses (MFL) were determined using a standardized pads’ weight method.…
Laparoscopic temporary clipping of uterine artery during laparoscopic myomectomy
2012
Purpose: Our aim is to study the feasibility and effect of bilateral laparoscopic temporary occlusion of uterine arteries by special vascular clamps on blood loss during laparoscopic myomectomy. Methods: Of 166 women with symptomatic uterine myomas necessitating surgical intervention who wished to retain their uteri, 80 underwent laparoscopic uterine artery clipping and myomectomy (experimental group) and 86 received laparoscopic myomectomy only (control group). Main outcome measures were operating time, number and weight of leiomyomas, blood loss, Doppler examination of the uterine arteries and complications of procedure. Results: In the experimental group the median hemoglobin drop measur…
Circulatory Effects of Peridural Block
1972
High peridural analgesia was studied in 20 volunteers in whom peridural block was achieved before and after removal of 10 ml/kg blood to simulate mild acute hemorrhage. One group was given 2 per cent lidocaine containing 1:200,000 epinephrine, while in another group lidocainc alone was used. The gro
Efficacy and safety of decompressive craniectomy with non-suture duraplasty in patients with traumatic brain injury.
2020
AbstractBackgroundDecompressive craniectomy is an important surgical treatment for patients with severe traumatic brain injury (TBI). Several reports have been published on the efficacy of non-watertight sutures in duraplasty performed in decompressive craniectomy. This study aims to evaluate the effectiveness of dura closure without sutures (non-suture duraplasty) in decompressive craniectomy for TBI.MethodsOne hundred and six patients were enrolled at a single trauma center between January 2017 and December 2018. We retrospectively collected the data and classified the patients into non-suture and suture duraplasty craniectomy groups. We compared the characteristics of patients and their …
Management of anemia: blood loss in orthopaedic surgery
2010
Major ortopaedic surgery and high energy trauma are often responsible of acute bleeding. Long bones and pelvis fractures are correlated with increased blood loss. The final consequence of a major bleeding is hypovolemic shock. The reduced oxygen tension of tissue could be responsible of heart attack, arrythmia, ictus, multi organ deficiency. For these reasons, it is important to immediately recognize and correct all potential bleeding in order to avoid complications. In orthopaedics the elective treatments in the managenment of hypovolemia are different. Blood banks and allogenic blood components have had an important impact on operative treatment and health care worldwide. erythropoietin h…

Improving the cementation of the tibial component in knee arthroplasty : a study of four techniques in the cadaver.
2021
Aims The main objective of this study is to analyze the penetration of bone cement in four different full cementation techniques of the tibial tray. Methods In order to determine the best tibial tray cementation technique, we applied cement to 40 cryopreserved donor tibiae by four different techniques: 1) double-layer cementation of the tibial component and tibial bone with bone restrictor; 2) metallic cementation of the tibial component without bone restrictor; 3) bone cementation of the tibia with bone restrictor; and 4) superficial bone cementation of the tibia and metallic keel cementation of the tibial component without bone restrictor. We performed CT exams of all 40 subjects, and mea…
