Indicação anestésica para o tratamento dos fraturados da face

The anesthesia for the treatment of maxilo-facial fractures should be good enough to the confort of the patient and assuring a quite operating field for the surgeon. Regional anesthesia is often used in the treatment of small fractures of the bones of the face. In children and non cooperative adults the general anesthesia is mandatory. In the great injuries of the face and in patients with “multiple trauma the general anesthesia is the best. choice. The orotraqueal entubations must be always performed and the traqueostomy should be done only in cases where the facial injury do not allow the orotraqueal entubations. In this brief discussion we also call attention for some points in general case of the patient such as treatment of the shock, respiratore failure and problems related.

Nerve-Sparing Robotic Radical Hysterectomy for the Beginner in Robotic Surgery

Robotic surgery is considered to be the optimal means of performing nerve-sparing radical hysterectomy (RH) because this procedure requires very precise surgery. Nerve-sparing RH has become increasingly popular in Japan. However, with open surgery the operating field is only visible to the surgeon performing this delicate procedure, which makes it difficult to educate trainee assistants. However, robotic surgery provides an expanded operation field that is visible to the surgeon and assistants, which makes it suitable for teaching purposes. To perform this procedure, it is necessary to become proficient in RH by laparotomy and then to become familiar with the characteristics of robotic surgery. In shifting from laparotomy to robotic surgery, we have found that experience with open surgery does not fully prepare surgeons for the new experiences and discoveries associated with robotic surgery, which may initially be problematic. We here provide clear instructions for the procedure with notes concerning particular potentially problematic aspects.

ISO 10993 Biological Evaluation of Novel Hemostatic Powder – 4SEAL®

Background:Hemostasis plays a crucial role during every surgery allowing for a bloodless operating field. Fast and effective surgery leads to a reduced risk of postoperative complications. One of the latest method for achieving homeostasis is the use of natural polysaccharide-based hemostatic powders. The study aimed to evaluate the biocompatibility according to the ISO 10993 standards of 4SEAL® Hemostatic powder.Methods:Chemical characterization (Headspace GC-MS, GC-MS, and ICP-MS), cytotoxicity, genotoxicity (MLA and AMES), endotoxin contamination, sensitization potential, intracutaneous reactivity, acute and subacute systemic toxicity with implantation, and pyrogenicity were evaluated to investigate the biocompatibility of the 4SEAL® Hemostatic powder. Studies were conducted according to ISO 10993 standards.Results:The biocompatibility requirements with accordance to ISO 10993-1 for 4SEAL® Hemostatic powder were met.Conclusions:4SEAL® Hemostatic powder is a promising new hemostatic agent with a wide range of potential applications and excellent biocompatibility.

Anterior prompt for debridement and myoplasty femoral neck and head osteomyelitis

The known anterior prompts to the femoral neck are non-traumatic, but they exclude the possibility of myoplasty and are not large enough for intra-articular sequestrectomy.Objective. The aim of the study was to develop an anterior prompt to the hip joint for sequestrectomy with myoplasty.Materials and research methods. For surgery neck and head of the hip osteomyelitis we perform a semi-oval incision in the projection of the femoral head, from the anterior spines of the ilium we cut off the tendons of the sartorius and rectus head of the quadriceps femoris muscles. An operating field is formed, which allows sequestrectomy to be performed. Plasty of the osteomyelitis cavity is performed with the proximal parts of the two anterior ileofemoral muscles. The operating field, if necessary, can be increased by temporary transection of the lumbar-iliac muscle tendon.Research results. The key to the anterior surgical prompt to the hip joint is the sartorius and rectus head of the quadriceps. The length of the surgical wound reaches 17–22 cm, and the width is 16–18 cm. With the mobilized proximal part of the sartorius muscle, we fill the entire bone cavity in the neck and head of the femur. Of the 12 operated patients, 11 (91.7 ± 7.6 %) had a stable long-term remission.Conclusion. The proposed approach is less traumatic and allows you to operate at an angle of about 90°. It complements the advantages of the known anterior prompts and is devoid of their disadvantages.

Relevance and Recommendations for the Application of Cardioplegic Solutions in Cardiopulmonary Bypass Surgery in Pigs

Cardioplegic solutions play a major role in cardiac surgery due to the fact that they create a silent operating field and protect the myocardium against ischemia and reperfusion injury. For studies on cardioplegic solutions, it is important to compare their effects and to have a valid platform for preclinical testing of new cardioplegic solutions and their additives. Due to the strong anatomical and physiological cardiovascular similarities between pigs and humans, porcine models are suitable for investigating the effects of cardioplegic solutions. This review provides an overview of the results of the application of cardioplegic solutions in adult or pediatric pig models over the past 25 years. The advantages, disadvantages, limitations, and refinement strategies of these models are discussed.

Bromferron in surgical practice

Despite the abundance of means and methods for disinfecting the operating field and hands, most surgeons carry out their work with an old, proven drug iodine tincture.

EMERGENCY SURGERY IN COMPLEX INCISIONAL HERNIAS MANAGEMENT

Introduction. Complex incisional hernias are a surgical challenge and a current socio-economic problem. In the emergency surgery of this pathology, the surgeon faces the need to obtain a "tension-free" hernia repair being limited in the use of parietal prosthesis due to the frequent needs of opening the gastrointestinal tract and thus contamination of the operating field. Purpose. The aim of this study is to evaluate and adapt emergency surgical treatment in order to reduce the risk of postoperative complications. Material and methods. The present study has a retrospective character and evaluates a group of 390 patients with complex incisional hernias admitted and operated in the General and Emergency Surgery III section of the Bucharest University Emergency Hospital during 2008-2018. Results. We identified 390 patients diagnosed with complex incisional hernias, of whom 95 were presented to the hospital as an emergency.The prosthetic hernioraphy was used in 51 of these patients, and complications were found in 18 patients in the total study group, ranging from wound infection to death. Discussions. The occurrence of postoperative complications was not statistically significantly associated with emergency surgical treatment. Instead, vital complications were much more common in this group. Conclusions. Increasing the degree of information and education of the patient, increasing addressability and avoiding emergency operations for this pathology are long-term objectives in the treatment of complex incisional hernia pathology.

Radical removal of advanced cancer of the oral cavity and oropharynx

Surgery for advanced cancer of the oral cavity and oropharynx are among the most difficult. This is due to the topographical and anatomical features that limit the operating field and the proximity of the internal carotid artery, which penetrates into the skull without branches. Her injury and bandaging are fraught with lethality. In the postoperative period, due to a violation of the function of swallowing, there is a stagnation of oral fluid in the oral cavity, which pro[1]motes healing by secondary tension. The functions of the oropharynx are impaired: swallowing, chewing, breathing and speech.Purpose of the study. To develop an operation in patients with advanced cancer of the oral cavity and oropharynx, allowing to visualize the area of the tumor with it’s radical removal and postoperative healing without suppuration.Patients and methods. We’ve operated a patient with advanced cancer of the oral cavity and oropharynx with me[1]tastases to the cervical lymph nodes (T4 N1 M0 – IV st.). Cervical lymphodessection and removal of the tumor from the oral cavity and oropharynx was performed according to the method developed at the National Medical Research Centre for Oncology of the Ministry of Health of Russia: the tumor was removed after a preliminary modified mandib-ulotomy. Good visualization allowed for a radical operation, after which a urostoma was formed, which promotes the free flow of oral fluid from the oral cavity, without its stagnation and without suppuration of the tissues. The jaw was restored with two titanium mini-plates.Results. The healing was carried out by primary tension. On the 7th day after the operation, breathing was restored[1]decanulated. On day 20, epithelialization of the wound surface of the oral cavity and oropharynx occurred. The nasoesophageal probe was removed. Plastic orostoma was produced. By this time, the functions of the oropharyngeal region were partially restored: chewing, swallowing, and speech. Discharged home. Remission for more than 2 years.Conclusions. Previously performed modifi ed mandibulotomy in patients with advanced cancer of the oral cavity and oropharynx, allows you to expand the view of the operating field and provide a radical operation. The formed orostoma, preventing suppuration in the oral cavity, accelerates healing with the restoration of functions: chewing, swallowing, breathing and speech.
