statement of the problem: due to shortage of icu beds in hospitals, knowing what kind of orthognathic surgery patients more need icu care after surgery would be important for surgeons and hospitals to prevent unnecessary icu bed reservation. purpose: the aim of the present study was to determine what kinds of orthognathic surgery patients would benefit more from icu care after surgery. material...

The cavernous hemangiomas of the liver are usually small sized and asymptomatic. Most of them are incidentally diagnosed and a very small portion requires therapy. Giant hemangioma can be symptomatic, and this condition is the indication for treatment. The striking complication of surgical treatment of cavernous hemangiomas is intra-operative blee...

5α-reductase inhibitors (5α-RIs), including finasteride and dutasteride, are commonly used medical therapies for benign prostatic hyperplasia (BPH). Many studies reported that preoperative 5α-RI had impact on intraoperative haemorrhage during surgery for BPH, but it was still in controversial. So, we conducted a systematic review of the effects and mechanisms of 5α-RIs on intraoperative bleedin...

Juvenile nasopharyngeal angiofibroma (JNA) is a rare, benign and locally invasive tumor. Massive bleeding because of vascularity of tumor and postoperative recurrence are potential problems of management. Endonasal approach reduces the rate of postoperative recurrence, intraoperative bleeding, and complications of surgery, time of operation and duration of hospitalization. In this article, we r...

Background A landmark for the identification of lingual artery (LA) through a transoral perspective can provide surgeons with an easy method to prevent and manage intraoperative bleeding during approach base tongue (BOT). Methods Thirteen five head neck specimens were dissected identify assess reliability point (LP) as new LA at BOT. The pathway 42 LAs was radiologically evaluated; axial depth ...

AIMS To examine possible benefits of intravitreal bevacizumab (IVB) pretreatment in vitrectomy for severe diabetic retinopathy. METHODS A comprehensive literature search was performed using the Cochrane Collaboration methodology to identify randomised controlled trials and comparative studies of vitrectomy with or without IVB pretreatment for severe or complicated diabetic retinopathy. Meta-a...

BACKGROUND Breast reduction surgery is a common cosmetic surgery with a high incidence of blood loss and transfusion. In this surgery, the reduction of blood loss related to surgical manipulation and the volume of resected tissue is a target. In the present study, we compared the effects of esmolol-induced controlled hypotension on surgical visibility, surgical bleeding, and the duration of sur...

One of the main complications of the orthognatic surgeries of mandible and maxilla is the intraoperative bleeding due to the high blood supply of the region. Severe bleeding increases the possibility of need for blood transfusion. Transfusion increases the risk of transmitting blood-borne diseases and blood mismatch reactions. In order to decrease the incidence of blood transfusion and its comp...
