Review
Unintentional hypothermia (core temperature < 36 °C) is a common side effect in patients undergoing surgery. Several patient-centred and external factors, e.g., drugs, comorbidities, trauma, environmental temperature, type of anaesthesia, as well as extent and duration of surgery, influence core temperature. Perioperative hypothermia has negative effects on coagulation, blood loss and transfusion requirements, metabolization of drugs, surgical site infections, and discharge from the post-anaesthesia care unit. Therefore, active temperature management is required in the pre-, intra-, and postoperative period to diminish the risks of perioperative hypothermia. Temperature measurement should be done with accurate and continuous probes. Perioperative temperature management includes a bundle of warming tools adapted to individual needs and local circumstances. Warming blankets and mattresses as well as the administration of properly warmed infusions via dedicated devices are important for this purpose. Temperature management should follow checklists and be individualized to the patient's requirements and the local possibilities.

Review
The number of lung transplantations is progressively increasing worldwide, providing new challenges to interprofessional teams and the intensive care units. The outcome of lung transplantation recipients is critically affected by a complex interplay of particular pathophysiologic conditions and risk factors, knowledge of which is fundamental to appropriately manage these patients during the early postoperative course. As high-grade evidence-based guidelines are not available, the authors aimed to provide an updated review of the postoperative management of lung transplantation recipients in the intensive care unit, which addresses six main areas: (1) management of mechanical ventilation, (2) fluid and hemodynamic management, (3) immunosuppressive therapies, (4) prevention and management of neurologic complications, (5) antimicrobial therapy, and (6) management of nutritional support and abdominal complications. The integrated care provided by a dedicated multidisciplinary team is key to optimize the complex postoperative management of lung transplantation recipients in the intensive care unit.

Review
OBJECTIVE
This paper highlights the hydrocephalus research efforts undertaken at AIIMS, New Delhi, supporting progress in the field.
MATERIAL
Over a period of three decades, basic research, clinical investigations, and multicentric studies were undertaken. This report will review the work mainly to emphasize the need for future generations to pursue further research. Studies that impacted hydrocephalus care (mainly in India) are described, and some of these findings may be useful in other resource-challenged situations.
RESULTS
Investigative studies on the effect of shunting on brainstem auditory evoked responses (BAER), transcranial Doppler (TCD), and CT-SPECT were published offering management options for patients. Participation in the International Infant Hydrocephalus Study (IIHS) study offered opportunities to compare our approaches and develop modifications in patient care. This effort proved shunting was equal or better for young children with congenital aqueductal stenosis. Shunt infection protocols and changes made in a systematic manner helped develop local protocols to reduce postoperative shunt infections.
CONCLUSIONS
Hydrocephalus research over three decades at AIIMS, New Delhi was productive and educational, confirming that locally performed investigative work can help in decision making. Further studies and active participation in international efforts are necessary to advance the field.

Meta-Analysis Review
OBJECTIVE
To evaluate the effects of different surgical dressings in reducing surgical site infection (SSI) and identify the optimal dressings.
METHODS
Randomized controlled trials investigating the application of surgical dressings were retrieved from electronic databases, including MEDLINE, EMBASE, and the Cochrane Library. The odds ratios (ORs) of the SSI rate were compared by direct meta-analysis, and the surface under the cumulative ranking (SUCRA) curve values were calculated based on the Bayesian theorem. A node-splitting model was applied to analyse the consistency of the comprehensive comparison results.
RESULTS
Twenty-two studies containing 5487 participants were pooled for the comprehensive comparison. Among all the studies included, 9 types of surgical dressings were identified for comparison. The results of the direct meta-analysis revealed that novel dressings significantly reduced the overall SSI rate with an OR of 1.026 (95% CI: 1.013-1.040, p < 0.001), which was determined to have low heterogeneity (I = 32.1%). Specifically, 3 types of dressings presented significant effects in reducing SSI, namely, mupirocin-containing (OR = 1.076, 95% CI: 1.014-1.142, p = 0.015), dialkylcarbamoyl-chloride-containing (OR = 1.047, 95% CI: 1.012-1.083, p = 0.008) and vitamin E (VE)-silicone-containing (OR = 1.129, 95% CI: 1.016-1.255, p = 0.025) dressings. Network meta-analysis demonstrated that the VE-silicone dressing (SUCRA = 0.37) was the optimal dressing, followed by the mupirocin dressing, with a SUCRA of 0.31.
CONCLUSION
The present network meta-analysis identified the superiority of VE-silicone and mupirocin dressings in preventing SSI. The evidence-based results provide suggestions and directions for future investigations on surgical dressings. More large-scale trials with rigorous designs are warranted to clarify the clinical value of novel dressings in surgical incision management.

Review
Hepatitis C virus (HCV) infection is one of the primary causes of liver cirrhosis and hepatocellular carcinoma. In hemodialysis patients, the rate of HCV infection is high and is moreover associated with a poor prognosis. In liver transplantation patients with HCV infection, recurrent HCV infection is universal, and re-infected HCV causes rapid progression of liver fibrosis and graft loss. Additionally, in patients with HCV and human immunodeficiency virus (HIV) co-infection, liver fibrosis progresses rapidly. Thus, there is an acute need for prompt treatment of HCV infection in these special populations (i.e., hemodialysis, liver transplantation, HIV co-infection). However, until recently, the standard anti-HCV treatment involved the use of interferon-based therapy. In these special populations, interferon-based therapies could not achieve a high rate of sustained viral response and moreover were associated with a higher rate of adverse events. With the development of novel direct-acting antivirals (DAAs), the landscape of anti-HCV therapy for special populations has changed dramatically. Indeed, in special populations treated with interferon-free DAAs, the sustained viral response rate was above 90%, with a lower incidence and severity of adverse events.

Meta-Analysis Review
BACKGROUND
The benefit results of postoperative tight glycemic control (TGC) were controversial and there was a lack of well-powered studies that support current guideline recommendations.
METHODS
The EMBASE, MEDLINE, and the Cochrane Library databases were searched utilizing the key words "Blood Glucose", "insulin" and "Postoperative Period" to retrieve all randomized controlled trials evaluating the benefits of postoperative TGC as compared to conventional glycemic control (CGC) in patients undergoing surgery.
RESULTS
Fifteen studies involving 5053 patients were identified. As compared to CGC group, there were lower risks of total postoperative infection (9.4% vs. 15.8%; RR 0.586, 95% CI 0.504 to 0.680, p < 0.001) and wound infection (4.6% vs. 7.2%; RR 0.620, 95% CI 0.422 to 0.910, p = 0.015) in TGC group. TGC also showed a lower risk of postoperative short-term mortality (3.8% vs. 5.4%; RR 0.692, 95% CI 0.527 to 0.909, p = 0.008), but sensitivity analyses showed that the result was mainly influenced by one study. The patients in the TGC group experienced a significant higher rate of postoperative hypoglycemia (22.3% vs. 11.0%; RR 3.145, 95% CI 1.928 to 5.131, p < 0.001) and severe hypoglycemia (2.8% vs. 0.7%; RR 3.821, 95% CI 1.796 to 8.127, p < 0.001) as compared to CGC group. TGC showed less length of ICU stay (SMD, - 0.428 days; 95% CI, - 0.833 to - 0.022 days; p = 0.039). However, TGC showed a neutral effect on neurological dysfunction (1.1% vs. 2.4%; RR 0.499, 95% CI 0.219 to 1.137, p = 0.098), acute renal failure (3.3% vs. 5.4%, RR 0.610, 95% CI 0.359 to 1.038, p = 0.068), duration of mechanical ventilation (p = 0.201) and length of hospitalization (p = 0.082).
CONCLUSIONS
TGC immediately after surgery significantly reduces total postoperative infection rates and short-term mortality. However, it might limit conclusion regarding the efficacy of TGC for short-term mortality in sensitivity analyses. The patients in the TGC group experienced a significant higher rate of postoperative hypoglycemia. This study may suggest that TGC should be administrated under close glucose monitoring in patients undergoing surgery, especially in those with high postoperative infection risk.

Review
The recent development of high-frequency ultrasonography transducers has provided better accuracy and improved the ability to image more superficial body structures. Ultrasonography is a widely available, inexpensive, comparative, and dynamic imaging technique that involves no radiation exposure and has no other adverse effects. Ultrasonography must always be combined with a medical history, physical examination, and radiographic assessment. What is ultrasound-assisted orthopaedic surgery? This approach consists in the use of ultrasonography by orthopaedic surgeons during patient visits and/or in the operating room. Similar to arthroscopy, ultrasonography is used as a complementary technique by physicians involved in the management of musculo-skeletal disease (e.g., radiologists, rheumatologists, and sports physicians). What knowledge of biophysics is needed to use ultrasonography? The surgeon must be familiar with the mechanisms by which the ultrasound waves are generated and received during B-mode and Doppler ultrasonography and with possible types of image artefacts. What is the procedure for examining a structure by ultrasonography? Each anatomic component must be assessed along two perpendicular planes in scanning mode. What does ultrasonography contribute during patient visits? Ultrasonography provides additional diagnostic information and helps to explain the pathological process to the patient. How does the contribution of ultrasonography vary across body sites and pathological processes? Ultrasonographic imaging is easier at some body sites than at others. Ultrasonography can provide useful information in patients with joint disease, sports injuries, osteo-articular infections, peripheral neuropathy, or tumours. What is interventional ultrasonography in orthopaedic surgery? Ultrasound-guided orthopaedic interventions include injections, aspirations, and minimally invasive surgical procedures. How can orthopaedic surgeons incorporate ultrasonography into their practice? The surgeon must purchase an ultrasound machine dedicated to the musculo-skeletal system and follow the necessary training courses.

Review
INTRODUCTION
Postoperative pulmonary infections are associated with cough, phlegm, shortness of breath, chest pain, temperature above 38 degrees C, and pulse rate above 100 a minute. Up to half of people may have asymptomatic chest signs after surgery, and up to a quarter develop symptomatic disease. The main risk factor is the type of surgery, with higher risks associated with surgery to the chest, abdomen, and head and neck compared with other operations. Other risk factors include age over 50 years, chronic obstructive pulmonary disease (COPD), smoking, hypoalbuminemia, and being functionally dependent.
METHODS AND OUTCOMES
We conducted a systematic review and aimed to answer the following clinical question: What are the effects of interventions to prevent postoperative pulmonary infections? We searched: Medline, Embase, The Cochrane Library, and other important databases up to May 2007 (BMJ Clinical Evidence reviews are updated periodically, please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA).
RESULTS
We found 17 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions.
CONCLUSIONS
In this systematic review we present information relating to the effectiveness and safety of the following interventions: advice to stop smoking preoperatively, anaesthesia, lung expansion techniques, and postoperative nasogastric decompression.

BioMed Research International 2021To study the effect on infection factors and nursing care of postoperative incision in gynecological cancer patients.
PURPOSE
To study the effect on infection factors and nursing care of postoperative incision in gynecological cancer patients.
METHOD
72 patients with gynecological malignant tumors who came to the hospital from January 2019 to December 2019 were selected as the research objects. They were divided into the study group and control group by cluster random sampling. The control group was given routine nursing mode, including matters needing attention in surgery, health education, prevention of complications, and dietary guidance. The study group implemented the high-quality nursing mode on the basis of the control group. Postoperative situation, incision infection rate, and quality of life were observed and compared between the two groups.
RESULTS
The control group's time to get out of bed, postoperative eating time, postoperative exhaust time, and hospital stay were longer than those of the study group. The comparison of the postoperative related conditions of the two groups showed that < 0.05, which indicated that the difference was statistically significant. The postoperative incision infection rate in the study group was 2.78%, and in the control group, the postoperative incision infection rate was 19.44%; the postoperative incision infection rate in the study group was significantly lower than that in the control group. The difference was statistically significant, < 0.05. The factors affecting the quality of life of patients in the study group were lower than that of the control group, and the difference was statistically significant, < 0.05. Time to get out of bed, postoperative eating time, postoperative exhaust time, hospital stay, and quality of life were the main influencing factors of postoperative incision infection in gynecological tumors.
CONCLUSION
Time to get out of bed, postoperative eating time, postoperative exhaust time, hospital stay, and quality of life were the main influencing factors of postoperative incision infection in gynecological tumors. High-quality nursing intervention had better clinical nursing effect in preventing postoperative incision infection. It should be widely used in clinical nursing.
