Clinical trials

The aim of this study is to evaluate the ganglion Impar block in the prevention of postoperative pain after anal surgery.

Post-surgical delirium in patients undergoing open heart surgery. Introduction Delirium occurs after open heart surgery may reach about 1/3 of the patients.(1) Aim The aim of this study is to determine the incidence of delirium after open heart surgery and the associated risk factors in Alexandria University hospital. Patients and Methods The study will be done on patients undergoing open heart surgery in Alexandria University hospitals from January 5th 2019 till January 4th 2020. The 6-item Cognitive Impairment Test (6CIT) and SPMSQ questionnaire will be used. SPMSQ will be done preoperative and daily for 3 days postoperative, at day 7. Phone call for SPMSQ will be done 3, 6 9 and 12 months after surgery.

Post-surgical delirium in patients undergoing radical cystectomy. Introduction Delirium occurs after major abdominal surgery may reach about 15% of the patients.(1) Aim The aim of this study is to determine the incidence of delirium after radical cystectomy surgery and the associated risk factors in Alexandria University hospital. Patients and Methods After approval of local ethical committee and patient consent, the study will be done on patients undergoing radical cystectomy surgery in Alexandria University hospitals from January 5th 2019 till January 4th 2020. The 6-item Cognitive Impairment Test (6CIT) and SPMSQ questionnaire will be used. SPMSQ will be done preoperative and daily for 3 days postoperative, at day 7. Phone call for SPMSQ will be done 3, 6, 9 and 12 months after surgery.

Mandibular reconstruction is necessary following trauma, tumour resections and extensive infections resulting in severe defects of the mandibular arch. For reconstructing large and recurrent defects, the vascularized free flaps are currently regarded as the gold standard. The use of these flaps, however, presents several major inconveniences. Although regenerative medicine in the field of cranio-maxillofacial reconstruction has now become a common practice, the main technical challenge is still related to vascularization of the regenerated tissue in large defects. Axial vascularization of constructs using a microvascular arteriovenous fistula/loop (AV loop) aims at providing the construct with blood supply through a defined and dedicated vascular axis. This technique was successfully demonstrated in some case reports, but was never applied in the craniofacial region. The current study aims to apply and assess the technique of axial vascularization using the AV loop of a bone substitute to reconstruct mandibular defects.
