Total hip arthroplasty (THA) is associated with blood loss ranging from 300 to 2000 mL. Tranexamic acid (TXA) is frequently administered prophylactically during this procedure to reduce blood loss by inhibiting fibrinolysis or by stopping naturally occurring clot resolution. TXA is employed currently based on a surgeon's preference. The objective of this study is to quantitate the degree of fibrinolysis using rotational thromboelastometry (ROTEM) and investigate the role of TXA prophylaxis on blood loss in patients undergoing THA in a double-blind fashion. Our hypothesis is that fibrinolysis is minimal at most and TXA prophylaxis is not necessary during THA. All patients, whether they receive TXA or normal saline, will not be at risk, as at this time no data exists to determine which approach is safer or more effective. This is the first study to compare TXA vs. placebo in a double-blinded, randomized controlled trial.
This is the first prospective study in Hong Kong that recruit patients with poor neurological status after intracranial aneurysm rupture in all seven public neurosurgical services in Hong Kong. This study assesses whether ultra-early aneurysm treatment improves outcomes in patients with poor neurological status after intracranial aneurysm rupture in Hong Kong. These data are essential to understand the impact of the disease and for future service development in Hong Kong.
Uterine leiomyomas (fibroids) are the most common benign tumors among women. Fibroids are found in approximately 20% of women over 35 years of age. In 20-50% of patients, fibroids may cause problems such as heavy menstrual bleeding, anemia, pelvic pain, pressure symptoms from extrinsic compression of the colorectal and urinary tract. Surgery is indicated for symptomatic uterine leiomyomas; hysterectomy for women who have completed childbearing (women > 40 years old), and myomectomy for women <40 years old who wish to preserve uterus and fertility.
The interrelationship of restorative dentistry and periodontics is a dynamic one. The interactions between restorative dentistry and periodontal health have been well-documented both clinically and histologically. The interplay between periodontics and restorative dentistry is present at many fronts, including location of restorative margins, alloy sensitivity, crown contours, and response of the gingival tissues to restorative preparations. Periodontal tissues form the foundation for proper esthetics, function, and comfort of the dentition, as well as the periodontal health at the restorative gingival interface consider as prerequisite for successful outcome. Success of fixed prosthodontics restorations is largely dependent upon the long term health and stability of the surrounding periodontal structures. The purpose of the present study was to evaluate the clinical efficacy of 4 new gingival retraction systems; traxodent, Gingitrac, Nocord, and cord , on the basis of the time taken for placement, hemorrhage control ,the amount of horizontal gingival displacement and periodontal parameter (PI, GI, CAL and PD).
Octreotide is used to decrease portal pressure of cirrhotic patients admitted for variceal bleeding. When patients are in haemorrhagic shock, the recommended drug to increase arterial pressure is norepinephrine. Microcirculatory effects of octreotide when it is added to noradrenaline has not been investigated yet. The aim of the study is to evaluate the effect of octreotide plus norepinephrine for patient with haemorrhagic shock after variceal bleeding.
Hundred (100) patients with primary postpartum hemorrhage during caesarean section due to atonic uterus will be recruited for this study.and randomized to either B lynch or Bakeri Ballon B-Lynch: A 70 mm round bodied hand needle on which a No. 2 absorbable suture is mounted is used to puncture the uterus 3 cm from the right lower edge of the uterine incision and 3 cm from the right lateral border. The mounted No. 2 absorbable suture is threaded through the uterine cavity to emerge at the upper incision margin 3 cm above and approximately 4 cm from the lateral border (because the uterus widens from below upwards). The absorbable suture now visible is passed over to compress the uterine fundus approximately 34 cm from the right cornual border. The absorbable suture is fed posteriorly and vertically to enter the posterior wall of the uterine cavity at the same level as the upper anterior entry point. The absorbable suture is pulled under moderate tension assisted by manual compression exerted by the first assistant. The length of the absorbable suture is passed back posteriorly through the same surface marking as for the right side, the suture lying horizontally. The absorbable suture is fed through posteriorly and vertically over the fundus to lie anteriorly and Research Template 7 Final Version: 1/6/2018 vertically compressing the fundus on the left side as occurred on the right. The needle is passed in the same fashion on the left side through the uterine cavity and out approximately 3 cm anteriorly and below the lower incision margin on the left side. The two lengths of absorbable suture are pulled taught assisted by bi-manual compression to minimize trauma and to achieve or aid compression. During such compression the vagina is checked that the bleeding is controlled. As good hemostasis is secured and whilst the uterus is compressed by an experienced assistant the principal surgeon throws a knot (double throw) followed by two or three further throws to secure tension. The lower transverse uterine incision is now closed in the normal way, in two layers, with or without closure of the lower uterine segment peritoneum. BALLOON INSERTION Insert the balloon portion of the catheter in the uterus; making certain that the entire balloon is inserted past the cervical canal and internal ostium. NOTE: Avoid excessive force when inserting the balloon into the uterus. Place a Foley catheter in patient bladder to collect and monitor urine output. To ensure maintenance of correct placement and maximize tamponade effect, the vaginal canal may be packed with iodine or antibiotic soaked vaginal gauze at this time.
Veno arterial extracorporeal membrane oxygenation (VA ECMO) is used, for cardiogenic shock, refractory cardiac arrest and post cardiotomy cardiac failure. Bleeding is frequent complications during VA ECMO and is associated with increased mortality. The aim of our study was to identify early factors associated with major bleeding in patients supported by VA ECMO
The main objective of this study is to assess safety and efficacy of elagolix compared to placebo in reducing heavy menstrual bleeding (HMB) associated with uterine fibroids in premenopausal women. The primary hypothesis is that elagolix, compared to placebo, reduces HMB associated with uterine fibroids in premenopausal women.
Neurologic dysfunction is common in aneurysmal subarachnoid hemorrhage (aSAH) patients. As we know, after the initial injury, secondary insults including poor cerebral perfusion are main contributors to poor outcome and their early detection and amelioration are keystone to neurocritical care. Nonetheless, the guidelines for blood pressure management still recommend a single target blood pressure for critically ill patients: the Brain Trauma Foundation (BTF) guidelines recommend maintaining CPP between 60 and 70 mmHg; Some guidelines recognize that patients with a history of hypertension may require a higher MAP. However, these guidelines do not currently recommend cerebral autoregulation-guided therapy and leave many unanswered questions. Cerebral autoregulation is the mechanism that maintains cerebral blood supply, hence CBF approximately constant despite changes in MAP or, more precisely, despite changes in CPP. Maintaining blood pressure within the cerebral blood flow (CBF) autoregulation range (termed "optimal MAP") is associated with improved outcomes for patients. The observational data suggests that management of patients above or below CPPopt 5mmHg is associated with better outcomes and mortality than the other greater variation range. The most commonly used method for monitoring dynamic cerebrovascular reactivity is the pressure reactivity index (PRx) that uses ICP as a surrogate for CBV. However, assessing the PRx requires invasive ICP monitoring which limits its application in many clinical areas. Alternatively, in the absence of invasive intracranial pressure monitoring to determine CPP, a continuous autoregulation monitoring can be accomplished by the continuous correlation between transcranial Doppler (TCD)-measured CBF velocity of the middle cerebral artery and the mean arterial blood pressure (termed mean velocity index or Mx). Mx is a validated index of cerebral autoregulation based on measures of cerebral perfusion pressure and mean flow velocity on transcranial doppler but is impractical for longer-term monitoring and requires system training, the results are operator-dependent. Near-infrared spectroscopy (NIRS) measurements is another alternative for real-time autoregulation monitoring in the form of a Tissue Oxygenation Index. In contrast to TCD, the NIRS sensors are very easy to apply (the probes attach to the forehead with self-adhesive pads) and do not require frequent calibration making them more suitable for long-term monitoring. Therefore, in this study, Patients in the intervention group will be monitored by continuous NIRS and invasive blood pressure monitoring. The correlation curve between ORI/THx and blood pressure will be obtained through continuous monitoring of 2 hours. According to the correlation curve, the optimal blood pressure which provides the optimal CPP will be determined. Then the optimal blood pressure which CPP is within 5 mmHg of CPPopt will be maintained as the target of blood pressure management for the intervention group during ICU stay.
