Introdução: A síntese de feridas de pele tensionadas é uma área que tem sido alvo de estudos para o desenvolvimento de técnicas de sutura que sejam capazes de realizar o fechamento primário dessas feridas com alívio de tensão, garantindo uma cicatrização adequada e evitando complicações como deiscência, edema, sangramento e infecção. Método: Esta pesquisa tratou-se de um estudo piloto, sendo a primeira apresentação da técnica de Sutura em Polia Retificada para síntese de feridas de pele tensionadas através do acompanhamento prospectivo, duplo-cego, de uma série de casos de 8 pacientes randomicamente admitidos no centro cirúrgico de um hospital de alta complexidade de uma cidade de médio porte. Resultados: A Sutura em Polia Retificada é uma técnica versátil e apta para lidar com feridas de pele tensionadas, uma vez que no intraoperatório conseguiu fechar por primeira intenção lesões de até 6,5 centímetros e de diferentes regiões tensionadas sem necessidade do uso de técnicas mais complexas, como retalhos, enxertos, zetaplastia e fechamento por segunda intenção. Além disso, no pós-operatório, houve redução dos escores da POSAS, indicando um processo de cicatrização satisfatório tanto para os observadores quanto para o paciente. É imprescindível mencionar, também, que o desfecho mais temido no seguimento dos pacientes com feridas tensionadas submetidos a fechamento primário - a deiscência - foi completamente evitado. Conclusão: A técnica é simples, confiável, segura e reprodutível, com curta curva de aprendizagem, de forma que a Sutura em Polia Retificada pode ser considerada como uma nova ferramenta a ser integrada ao arsenal cirúrgico.

Introduction: The synthesis of tensioned skin wounds is an area that has been the subject of studies for the development of suturing techniques that are capable of performing the primary closure of these wounds with tension relief, ensuring adequate healing, and avoiding complications such as dehiscence, edema, bleeding, and infection. Method: This research was a pilot study, being the first presentation of the Rectified Pulley Suture technique for the synthesis of tensioned skin wounds through prospective, double-blind monitoring of a series of cases of 8 patients randomly admitted to the surgical center of a high-complexity hospital in a mediumsized city. Results: Rectified Pulley Suture is a versatile technique suitable for dealing with tensioned skin wounds, since intraoperatively it was able to close, by first intention, lesions measuring up to 6.5 centimeters and in different tensioned regions without the need for the use of more extensive techniques. complex, such as flaps, grafts, Z-plasty, and secondary intention closure. Furthermore, post-operatively, there was a reduction in POSAS scores, indicating a satisfactory healing process for both observers and the patient. It is also essential to mention that the most feared outcome in the follow-up of patients with tension wounds undergoing primary closure - dehiscence - was completely avoided. Conclusion: The technique is simple, reliable, safe, and reproducible, with a short learning curve, so the Rectified Pulley Suture can be considered a new tool to be integrated into the surgical arsenal.

Intraoperative Wound Lavage System for Deep Neck Infection: A Retrospective Cohort Study

Abstract Introduction Multiple solutions are currently used to cleanse a deep neck infection (DNI), and a variety of devices are available to deliver wound irrigation solutions. An essential difference between these devices is the pressure that the irrigation solution exerts over the wound tissue. Objective To compare low-pressure and high-pressure irrigation delivery systems for wound cleansing in DNI. Methods we designed a retrospective cohort study and reviewed the medical records of patients operated on due to DNI from June 2016 to December 2017 at our institution. One cohort included patients treated with an intraoperative irrigation method that exerts low pressure over the irrigated tissue, and the other cohort, to a system capable of generating higher pressure. The Pearson Chi-squared test was used to analyze the data. Results A total of 42 patients whose ages ranged from 16 months to 72 years were included. The low-pressure irrigation system was used in 18 patients, and the high-pressure system was used in 24 patients. No statistical differences were observed regarding the irrigation methods, the complexity of the DNI, and the overall outcomes. Conclusions The present is the first study in which low- and high-pressure systems for wound lavage were evaluated in the treatment of DNI. When comparing these methods, we did not find one to be superior to the other; however, the additional cost associated with the high-pressure devices may not justify their in head and neck procedures.

Microbiological profile and antibiotic sensitivity of maxillofacial infections in an emergency hospital

Aim: To investigate the bacteriological profile of oral and maxillofacial infections and the pattern of sensitivity to a specific group of antibiotics in a reference emergency hospital in Brazil. Methods: This is a prospective cohort institutional study that studied patients affected by oral and/ or maxillofacial infections in a Brazilian emergency hospital, over a 12-month period, of different etiologies, through data collection, culture and antibiogram tests, and monitoring of the process of resolution of the infectious condition. The variables were analyzed using the chi-square and Mann-Whitney tests, using a significance level of 5%. Results: The sample consisted of 61 patients, 62.3% male. The mean age of participants was 34.3 years. Odontogenic infection was the most frequent etiology and the submandibular space was the most affected. The bacterial species Streptococcus viridans was isolated in 21.6% of cases. Levofloxacin, vancomycin and penicillin were the antibiotics with the highest frequency of bacterial sensitivity, while clindamycin and erythromycin showed the highest percentages of resistance. Conclusions: The results suggest that, among the most used antibiotics for the treatment of these infections, penicillin remains an excellent option of choice for empirical therapy

Resumo Fundamento A infecção do sítio cirúrgico (ISC) é uma importante complicação no pós-operatório de cirurgia cardíaca pediátrica associada ao aumento da morbimortalidade. Objetivos Identificar fatores de risco para a ISC após cirurgias cardíacas para correção de malformações congênitas. Métodos Este estudo caso-controle incluiu 189 pacientes com um ano completo e 19 anos e 11 meses, submetidos à cirurgia cardíaca em hospital universitário terciário de cardiologia de janeiro de 2011 a dezembro de 2018. Foi realizado registro e análise de dados pré, intra e pós-operatórios. Para cada caso foram selecionados dois controles, conforme o diagnóstico da cardiopatia e cirurgia realizada em um intervalo de até 30 dias para minimizar diferenças pré e/ou intraoperatórias. Para a análise dos fatores de risco foi utilizado o modelo de regressão binária logística. Significância estatística definida como valor de p<0,05. Resultados O estudo incluiu 66 casos e 123 controles. A incidência de ISC variou de 2% a 3,8%. Fatores de risco identificados: faixa etária de lactentes (OR 3,19, IC 95% 1,26 - 8,66, p=0,014), síndrome genética (OR 6,20, IC 95% 1,70 - 21,65, p=0,004), RACHS-1 categorias 3 e 4 (OR 8,40, IC 95% 3,30 - 21,34, p<0,001), o valor da proteína C reativa (PCR) de 48 horas pós-operatórias foi demonstrado como fator protetor para esta infecção (OR 0,85, IC 95% 0,73 - 0,98, p=0,023). Conclusão Os fatores de risco identificados não são variáveis modificáveis. Vigilância e medidas preventivas contínuas são fundamentais para reduzir a infecção. O papel do PCR elevado no pós-operatório foi fator protetor e precisa ser melhor estudado.

Abstract Background Surgical site infection is an important complication after pediatric cardiac surgery, associated with increased morbidity and mortality. Objectives We sought to identify risk factors for surgical site infection after pediatric cardiac surgeries. Methods A case-control study included patients aged between 1 year and 19 years and 11 months of age, submitted to cardiac surgery performed at a tertiary cardiac center from January 1 st , 2011, through December 31, 2018. Charts were reviewed for pre-, intra, and postoperative variables. We identified two randomly selected control patients with the same pathophysiological diagnosis and underwent surgery within thirty days of each index case. Univariate and multivariate logistic regression analyses were performed to identify risk factors. Statistical significance was defined as p<0.05. Results Sixty-six cases and 123 controls were included. Surgical site infection incidence ranged from 2% to 3.8%. The following risk factors were identified: Infant age (OR 3.19, 95% CI 1.26 to 8.66, p=0.014), presence of genetic syndrome (OR 6.20, CI 95% 1.70 to 21.65, p=0.004), categories 3 and 4 of RACHS-1 (OR 8.40, CI 95% 3.30 to 21.34, p<0.001), 48 h C-reactive protein level range was detected as a protective factor for this infection (OR 0.85, 95% CI 0.73 to 0.98, p=0.023). Conclusions The risk factors defined in this study could not be modified. Therefore, additional surveillance and new preventive strategies need to be implemented to reduce the incidence of surgical site infection. The increased CRP in the postoperative period was a protective factor that needs further understanding.

The most frequent antibiotic prophylaxis time in patients undergoing scheduled cesarean section was >120 minutes (34.08%) and ceftriaxone was administered in 84.86% of the population, which is mostly ASA II (97.83%). 100% of the wounds were superficial. Conclusions: In the present study, it was found that the prevalence of IHC in cesarean sections scheduled in HRAEV was 2.16%, a figure that is below the worldwide prevalence, given that the selected patients did not have some of the risk factors. added risk that increased the risk of SSI compared to other studies.

Terapia E-VAC como tratamiento de complicaciones en cirugía gastrointestinal en centro de referencia de gastroenterología en Colombia: Serie de casos

Las fístulas y dehiscencias anastomóticas postoperatorias gastrointestinales se presentan de forma frecuente y muchas son manejadas quirúrgicamente, sin embargo, las intervenciones endoscópicas han mostrado mejorar desenlaces de curación y tiempo de estancia hospitalaria. Se describe la experiencia de la terapia de cierre asistida por vacío (E-VAC), en el manejo de fístulas y dehiscencias anastomóticas postoperatorias, en un centro de referencia gastrointestinal en Colombia. Se realizó un estudio serie de casos en pacientes con dehiscencia de anastomosis y fístula a diferentes niveles del tracto digestivo, tratados mediante E-VAC, por el servicio de gastroenterología de la clínica universitaria Colombia, en Bogotá, durante un periodo comprendido de febrero 2019 y noviembre 2021. Se describieron variables sociodemográficas, clínicas y quirúrgicas. Se describen 6 casos, 4 de tracto digestivo inferior y 2 de tracto digestivo superior. El 83% fueron hombres, la edad media fue de 51,8 años (+/-17,5). La indicación de E-VAC fue fístula anastomótica colorrectal en el 66%, siendo la ubicación anatómica más frecuente la anastomosis colorrectal (66%), con menor frecuencia a nivel de los cardias (16%) y esófago (16%). El tamaño del defecto se describió entre el 20 y el 80% en pacientes sometidos a terapia E-VAC, siendo el tiempo promedio de hospitalización 22.5 días con un número de recambios promedio de siete por paciente. Las fugas y fístulas anastomóticas son complicaciones potencialmente mortales en pacientes llevados a intervenciones quirúrgicas gastrointestinales, en las que la terapia E-VAC ha mostrado ser eficaz y segura, promoviendo el cierre del defecto y el drenaje de colecciones presentes, igualmente disminuyendo el tiempo de estancia hospitalaria.

Gastrointestinal postoperative anastomotic leaks and fistulas occur frequently and many are managed surgically; however, endoscopic interventions have shown to improve healing outcomes and length of hospital stay. The experience of vacuum-assisted closure therapy (E-VAC) is described, in complications such as fistulasand postoperative anastomotic leaks, in a gastrointestinal reference center in Colombia. A case series study was carried out in patients with anastomotic leaks and fistulasat different levels of the digestive tract, treated by E-VAC, by the Gastroenterology Service in Colombia, during a period from February 2019 to November 2021. Sociodemographic, clinical and surgical variables were described. 6 cases are described, 4 from lower digestive tract and 2 from upper digestive tract. 83% were men; the mean age was 51.8 years (+/-17.5). The indication for E-VAC was colorectal anastomotic fistula in 66%; the most frequent anatomical location was near the anal region (66%), less frequently at the level of the cardia (16%) and esophagus (16%). The size of the defect was described between 20 and 80% in patients undergoing E-VAC therapy, with an average hospitalization length of stay of 22.5 days, with an average number of exchanges of seven per patient. Anastomotic leaks and fistulasare potentially fatal complications in gastrointestinal surgery. E-VAC therapy has shown to be effective and safe, promoting defect closure and drainage of collections present, also decreasing the length of hospital stay.

Removal Rate of the Tomofix® System after High Tibial Osteotomy is Higher Than Reported / A taxa de remoção do sistema Tomofix® após a osteotomia tibial alta é superior à relatada

Abstract Objective Medial open wedge high tibial osteotomy (MOWHTO) significantly relieves pain in the medial joint line in medial compartment osteoarthritis of the knee. But some patients complain of pain over the pes anserinus even 1 year after the osteotomy, which may require implant removal for relief. This study aims to define the implant removal rate after MOWHTO due to pain over the pes anserinus. Methods One hundred and three knees of 72 patients who underwent MOWHTO for medial compartment osteoarthritis between 2010 and 2018 were enrolled in the study. Knee injury and osteoarthritis outcome score (KOOS), Oxford knee score (OKS), and visual analogue score (VAS) were assessed for pain in the medial knee joint line (VAS-MJ) preoperatively, 12 months postoperatively, and yearly thereafter; adding VAS for pain over the pes anserinus (VAS-PA). Patients with VAS-PA ≥ 40 and adequate bony consolidation after 12 months were recommended implant removal. Results Thirty-three (45.8%) of the patients were male and 39 (54.2%) were female. The mean age was 49.4 ± 8.0 and the mean body mass index was 27.0 ± 2.9. The Tomofix medial tibial plate-screw system (DePuy Synthes, Raynham, MA, USA) was used in all cases. Three (2.8%) cases with delayed union requiring revision were excluded. The KOOS, OKS, and VAS-MJ significantly improved 12 months after MOWHTO. The mean VAS-PA was 38.3 ± 23.9. Implant removal for pain relief was needed in 65 (63.1%) of the103 knees. The mean VAS-PA decreased to 4.5 ± 5.6 3 months after implant removal (p < 0.0001). Conclusion Over 60% of the patients may need implant removal to relieve pain over the pes anserinus after MOWHTO. Candidates for MOWHTO should be informed about this complication and its solution.

Resumo Objetivo A osteotomia tibial alta com cunha de abertura medial (MOWHTO, do inglês medial open wedge high tibial osteotomy) alivia de forma significativa a dor na linha articular medial em casos de osteoartrite do compartimento medial do joelho. Alguns pacientes, porém, se queixam de dor nos tendões dos músculos sartório, grácil e semitendinoso (pata de ganso) mesmo 1 ano após a osteotomia, o que pode exigir a remoção do implante. Este estudo define a taxa de remoção do implante após a MOWHTO devido à dor nos tendões dos músculos sartório, grácil e semitendinoso. Métodos Cento e três joelhos de 72 pacientes submetidos à MOWHTO para tratamento da osteoartrite do compartimento medial entre 2010 e 2018 foram incluídos no estudo. A pontuação de desfecho de lesão no joelho e osteoartrite (KOOS, do inglês Knee Injury and Osteoarthritis Outcome Score), a pontuação dejoelho de Oxford (OKS, do inglês Oxford Knee Score) e a escala visual analógica (EVA) de dor na linha articular medial do joelho (EVA-MJ) foram avaliados antes da cirurgia. A EVA nos tendões dos músculos sartório, grácil e semitendinoso (EVA-PA) foi adicionada a essas avaliações, também realizadas 12 meses após o procedimento e, a seguir, anualmente. A remoção do implante foi recomendada em pacientes com EVA-PA ≥ 40 e consolidação óssea adequada em 12 meses. Resultados Trinta e três (45,8%) pacientes eram homens e 39 (54,2%), mulheres. A média de idade foi de 49,4 ±8,0, e o índice de massa corpórea (IMC) médio foi de 27,0 ± 2,9. O sistema placa-parafuso tibial medial Tomofix (DePuy Synthes, Raynham, MA, EUA) foi utilizado em todos os casos. Três (2,8%) casos foram excluídos devido ao retardo de consolidação e à necessidade de revisão. Os resultados nas escalas KOOS, OKS e EVA-MJ melhoraram significativamente 12 meses após a MOWHTO. A EVA-PA média foi de 38,3 ± 23,9. A remoção do implante para alívio da dor foi necessária em 65 (63,1%) dos 103 joelhos. Três meses após a remoção do implante, a EVA-PA média diminuiu para 4,5 ± 5,6 (p < 0,0001). Conclusão A remoção do implante pode ser necessária em mais de 60% dos pacientes para alívio da dor nos tendões dos músculos sartório, grácil e semitendinoso após a MOWHTO. Os candidatos à MOWHTO devem ser informados sobre esta complicação e sua resolução.

Regional analgesia and surgical site infections after colorectal surgery: a retrospective cohort analysis

Abstract Background The effect of regional analgesia on perioperative infectious complications remains unknown. We therefore tested the hypothesis that a composite of serious infections after colorectal surgery is less common in patients with regional analgesia than in those given Intravenous Patient-Controlled Analgesia (IV-PCA) with opiates. Methods Patients undergoing elective colorectal surgery lasting one hour or more under general anesthesia at the Cleveland Clinic Main Campus between 2009 and 2015 were included in this retrospective analysis. Exposures were defined as regional postoperative analgesia with epidurals or Transversus Abdominis Plane blocks (TAP); or IV-PCA with opiates only. The outcome was defined as a composite of in-hospital serious infections, including intraabdominal abscess, pelvic abscess, deep or organ-space Surgical Site Infection (SSI), clostridium difficile, pneumonia, or sepsis. Logistic regression model adjusted for the imbalanced potential confounding factors among the subset of matched surgeries was used to report the odds ratios along with 95% confidence limits. The significance criterion was p < 0.05. Results A total of 7811 patients met inclusion and exclusion criteria of which we successfully matched 681 regional anesthesia patients to 2862 IV-PCA only patients based on propensity scores derived from potential confounding factors. There were 82 (12%) in-hospital postoperative serious infections in the regional analgesia group vs. 285 (10%) in IV-PCA patients. Regional analgesia was not significantly associated with serious infection (odds ratio: 1.14; 95% Confidence Interval 0.87‒1.49; p-value = 0.339) after adjusting for surgical duration and volume of intraoperative crystalloids. Conclusion Regional analgesia should not be selected as postoperative analgesic technique to reduce infections.

Continuous deep irrigation combined with vacuum sealing drainage for the treatment of postoperative multidrug-resistant bacterial infections in wounds of patients with major artery injury / 中华创伤杂志

Objective:To compare the efficacy between deep continuous irrigation combined with vacuum sealing drainage (VSD) and routine dressing change in treating multidrug-resistant bacterial infections at the surgical wound site in patients with major vascular injury.Methods:A retrospective cohort study was conducted to analyze the clinical data of 28 patients with surgical wound infections by multidrug-resistant bacteria after major vascular injury treated at the First Affiliated Hospital of Henan University of Science and Technology from March 2015 to December 2021. There were 15 males and 13 females, aged 15-65 years [(41.8±12.9)years]. All patients received vascular graft surgery after major vascular injury. Postoperative microbiological culture indicated that the wound infections were caused by Carbapenem-resistant organisms (CRO) or vancomycin- resistant Enterococci (VRE), with no available sensitive antibiotics for treatment. The patients received surgical debridement every five days after vascular graft surgery and were divided into two groups to receive the subsequent treatments including a routine dressing change (routine dressing group, 14 patients) or a deep continuous irrigation combined with VSD (irrigation combined with VSD group, 14 patients). On the first day post-operation and then every 3 days, inflammatory indicators [white blood cell count, neutrophils, C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), and procalcitonin] were observed in the two groups (repeat tests when a patient′s condition changed). Microbiological cultures were applied with patient samples every 5 days to observe the wound and infection control. Comparisons were made between the two groups regarding the duration to normal levels of inflammatory indicators, duration to negative CRO or VRE cultures, visual analogue score (VAS) before and at 1, 2 and 3 hours after changing the irrigation fluid (changing the dressing), conditions of wound skin grafting or flap repair, and incidences of anastomotic fistula.Results:All patients were followed up for 12-24 months [(14.3±2.4)months], during which no wound redness, rupture, purulent discharge or infection recurrence was noted. The duration to normal levels was (9.4±2.4)days for white blood cells, (9.6±2.8)days for neutrophils, (9.8±3.1)days for CRP, (12.2±3.6)days for ESR, and (7.6±1.9)days for procalcitonin in the irrigation combined with VSD group, significantly shorter than those in the routine dressing group [(15.2±3.1)days, (13.6±3.4)days, (14.2±3.9)days, (19.9±3.3)days, and (12.9±4.1)days, respectively] (all P<0.01). The duration to negative CRO or VRE cultures was (13.9±3.1)days in the irrigation combined with VSD group, significantly shorter than that in the routine dressing group [(19.2±6.9)days] ( P<0.05). The VAS before and at 1, 2 and 3 hours after changing the irrigation fluid was (4.2±0.7)points, (4.1±0.9)points, (4.2±0.9)points and (4.1±0.8)points in the irrigation combined with VSD group, respectively, and was (4.3±0.6)points, (6.9±0.7)points, (5.4±0.9)points and (4.5±0.9)points in the routine dressing group, respectively. The VAS score in the irrigation combined with VSD group was significantly lower than that in the routine dressing group at 1 hour and 2 hours after changing the irrigation fluid (all P<0.01), while no significant differences were found before and at 3 hours after changing the irrigation fluid (all P>0.05). After infection control, 5 patients (35.7%) in the irrigation combined with VSD group required skin grafting or flap repair at the wound site, lower than 11 patients (78.6%) in the routine dressing group ( P<0.01). The incidence of anastomotic fistula was 7.1% (1/14) in the irrigation combined with VSD group, lower than 42.9% (6/14) in the routine dressing group ( P<0.05). Conclusion:When multidrug-resistant bacterial infections occur at the surgical wound site after major vascular injury, deep continuous irrigation combined with VSD performs better than routine dressing change in controlling infection as well as in reducing pain, rate of wound skin grafting or flap repair and incidence of anastomotic fistula, without reliance on antibiotics.

Construction of wound drainage tube time delay prediction model for patients with breast cancer / 中国实用护理杂志

Objective:To investigate the independent influencing factors of wound drainage tube time delay in patients with breast cancer and establish a predictive model.Methods:Patients admitted to Tianjin Medical University Cancer Hospital from January to November 2021 were selected as the research objects. They were divided into sword modeling group (156 cases) and verification group (86 cases) according to the admission time. Delayed time to postoperative wound drainage and extubation in breast cancer patients was the end point, 95 cases of 156 patients in the modeling group whose extubation time was less than or equal to 7 days were set as the normal group, 61 cases whose extubation time were more than 7 days were set as delayed group, and the influencing factors of the two groups were compared to establish the prediction model, Hosmer-Lemeshow test was conduct to verify the fitting effect, used the ROC curve to verify the prediction model performance.Results:Univariate and multivariate Cox proportional hazards regression analysis showed that patients' high BMI, related basic disease history, operation mode, axillary lymph node dissection, breast tumor size (T3, T4) and drainage fluid volume 48 hours (≥50 ml) after operation were independent influencing factors for wound drainage tube time delay ( P<0.05). The prediction model was P=0.822, and the area under the ROC curve was 0.877, and the Youden index was 0.605, the sensitivity was 0.736, and the specificity was 0.869. The research data of 86 cases in the validation group were used as the test set for internal and external validation of the model, and the model verification was 96.51%. Conclusion:This prediction model has a good effect, providing a reference basis for clinical medical workers.

Antibioticoprofilaxia em cirurgia adominal: quando recomendar? Posicionamento do Colégio Brasileiro de Cirurgia Digestiva / Antibiotic prophylaxis for abdominal surgery: when to recommend? brazilian college of digestive surgery position paper

ABSTRACT BACKGROUND: Surgical antibiotic prophylaxis is an essential component of perioperative care. The use of prophylactic regimens of antibiotics is a well-established practice that is encouraged to be implemented in preoperative/perioperative protocols in order to prevent surgical site infections. AIMS: The aim of this study was to emphasize the crucial aspects of antibiotic prophylaxis in abdominal surgery. RESULTS: Antibiotic prophylaxis is defined as the administration of antibiotics before contamination occurs, given with the intention of preventing infection by achieving tissue levels of antibiotics above the minimum inhibitory concentration at the time of surgical incision. It is indicated for clean operations with prosthetic materials or in cases where severe consequences may arise in the event of an infection. It is also suitable for all clean-contaminated and contaminated operations. The spectrum of action is determined by the pathogens present at the surgical site. Ideally, a single intravenous bolus dose should be administered within 60 min before the surgical incision. An additional dose should be given in case of hemorrhage or prolonged surgery, according to the half-life of the drug. Factors such as the patient's weight, history of allergies, and the likelihood of colonization by resistant bacteria should be considered. Compliance with institutional protocols enhances the effectiveness of antibiotic use. CONCLUSION: Surgical antibiotic prophylaxis is associated with reduced rates of surgical site infection, hospital stay, and morbimortality.

RESUMO RACIONAL: A antibioticoprofilaxia é um componente importante dos cuidados perioperatórios. OBJETIVOS: Abordar os principais aspectos da antibioticoprofilaxia em cirurgia digestiva. RESULTADOS: Ela é definida como a redução da carga de bactérias no sítio operatório através da obtenção de níveis séricos de antibiótico acima da concentração inibitória mínima no momento da incisão cirúrgica. Está indicada em cirurgias limpas com próteses e nas quais a consequência de uma eventual infecção seja grave, bem como em todas as cirurgias limpas-contaminadas e contaminadas. O espectro de ação do antibiótico deve ser de acordo com a flora esperada no sítio cirúrgico e deve ser administrado 60 minutos antes da incisão, em bolus, por via endovenosa e preferencialmente em dose única. Nos casos de hemorragia importante ou cirurgias mais longas, uma nova dose pode ser administrada. O peso do paciente, a história de alergia a medicamentos e a possibilidade de colonização por bactérias multirresistentes devem ser levados em conta. A aderência a protocolos institucionais aumenta a chance de uso adequado da antibioticoprofilaxia. CONCLUSÕES: A antibioticoprofilaxia está associada à redução das taxas de infecção do sítio cirúrgico, tempo de internação e morbidade.
