Intraoperative Goal-directed Blood Pressure and Dexmedetomidine

Perioperative organ injuriy remain an important threat to patients undergoing major surgeries. Intraoperative hypotension is associated with an increase in postoperative morbidity and mortality. Whereas individualized intraoperative blood pressure management is likely to decrease the incidence of postoperative organ injury when compared with standard blood pressure management strategy. Dexmedetomidine, a highly selective alpha2 adrenergic agonist, has been shown to provide organ protective effects. This study aims to investigate the impact of intraoperative goal-directed blood pressure management and dexmedetomidine infusion on incidence of postoperative organ injury in high-risk patients undergoing major surgery.

Epigenetics in PostOperative Pediatric Emergence Delirium

Emergence delirium (ED) infers the occurrence of behavior and cognition changes during the early postoperative period. Main signs and symptoms of ED are the disturbances of consciousness and awareness of the environment, with disorientation and perceptual alterations, including hypersensitivity to external stimuli and hyperactive motor behaviors. The incidence may be higher than 80%. Risk factors include pre-school age, use of sevoflurane, ophthalmologic and otorhinolaryngologic surgeries, child anxiety, parental or caregiver anxiety. The recurrence of ED is controversial. The only validated scale for diagnosis of ED is the PAED (Pediatric Anesthesia Emergence Delirium). Prevention is the best approach, as well as the use of alpha-2 agonists, propofol and total intravenous anesthesia. There are still no clear markers for postoperative delirium, especially ED. Cognitive alterations may be related to epigenetic modifications. Anesthesia-induced epigenetic changes may be the key to understanding perioperative complications and outcomes and is a field of future research in anesthesia. The study aims to analyze the DNA methylation profile in children with ED. A prospective, randomized study will be carried out in up to 322 children undergoing general anesthesia (inhalation group or intravenous group) to perform endoscopic procedures at the Instituto da Criança, Hospital das Clinicas, Faculdade de Medicina, Universidade de Sao Paulo, Brazil. Patients will have blood samples drawn, and analysis of the DNA methylation profile through the array technique will be performed in 40 children (20 of each group ) who presented ED as well as in 08 control cases. Also, the occurrence of ED will be correlated with the degree of anxiety of the child, parents and during anesthetic induction, in addition to comparing the two anesthetic techniques with the occurrence of ED and late postoperative cognitive alterations.

Postoperative Recovery and Comfort in Patients Undergoing Urologic Robotic Surgery

Previously published studies show that adding intrathecal morphine to general anesthesia can reduce the postoperative pain and length of stay (LOS) in varies types of surgery. A recent meta-analysis showed that the addition of intrathecal morphine at doses below 500µg did not increase the risk of respiratory depression compared with a control group receiving intravenous opioids. Epidural analgesia is uncommonly used for robot-assisted laparoscopic procedures due to the limited surgical trauma. In addition, the risks associated with the epidural itself such as infection and spinal hematoma are thought to outweigh its possible benefits for these procedures. At Linkoping University Hospital a combination of general anesthesia and intrathecal morphine in robot-assisted laparoscopic radical prostatectomy and in robotic-assisted laparoscopic cystectomy is now routinely used in order to improve postoperative recovery. However whether this approach is beneficial in other types of robotic-assisted urological procedures is unknown. Therefore the investigators aim to conduct a feasibility study for the use of intrathecal morphine combined with general anaesthesia in adult patients undergoing elective urologic laparoscopic robot-assisted surgery at Linkoping University Hospital. The investigators will include 30 patients in the study. The specific aims are to investigate the feasibility and sensitivity of Quality of Recovery 15 (QoR15), as an outcome tool measuring postoperative well-being in this patient cohort. The investigators will also investigate the feasibility of other outcome measures such as postoperative pain, post-anesthesia care unit LOS, occurrence of pruritus and hospital LOS. For planning of the timeframe of the future interventional study the investigators will use this feasibility study to examine the inclusion rate of study patients.

The Effect of Preoperative Oral Dexamethasone Supplementation on the Outcome of Thyroidectomised Patients.

Glucocorticoids are well known for their analgesic, anti-inflammatory, immunomodulatory and anti-emetic effects. Recovery time after thyroid surgery may depend on several factors, such as postoperative pain, nausea and vomiting, postoperative sore throat, voice disorders and symptomatic hypocalcaemia (low serum calcium level). However, there is little information in the literature about the preventive use of glucocorticosteroids in patients undergoing thyroid surgery. The aim of the study is to evaluate the clinical impact of preoperative oral dexamethasone supplementation on the surgical outcome in patients with multinodular goiter undergoing total thyroidectomy. Patients will be assigned to the supplementation group and the placebo group. In the supplementation group 8mg of dexamethasone will be administered orally one hour before surgery. In the postoperative period, the frequency and intensity of pain, nausea, vomiting, sore throat and hoarseness will be assessed. The incidence of symptoms of hypocalcaemia will also be evaluted. Preoperative and postoperative levels of vitamin D, cytokines, acute phase proteins and substances related to calcium metabolism will be measured in the blood. Cytokines levels in drainage fluid will also be assessed. The main hypothesis of the study is that in patients with supplementation postoperative discomfort and decrease in serum calcium and parathormone level and hypocalcemic symptoms will be less severe and the levels of proinflammatory substances will be decreased.

Protocol for Accelerated Recovery in Patients Undergoing Thoracic Surgical Procedures (PROSM). Study Randomized Comparative Between the Adoption of the Proposed Guidelines and the Traditional Method Currently Used in the Institution

Introduction: Aiming at reducing costs and optimizing the use of these financial resources, several postoperative recovery protocols have emerged that aim to reduce the length of hospital stay by accelerating surgical recovery.1,2 In view of the current Brazilian political and economic scenario allied to the existing scientific knowledge on the subject , the investigators developed a protocol that aims to meet this need using resources already available and offered in brazilian public health system. The investigators called this protocol as Protocol of Operative Recovery Santa Marcelina (PROSM) that had as inspiration the protocols of accelerated postoperative recovery already used in several European health services. Goals: To evaluate the impact of PROSM on the length of hospitalization in days and postoperative pain (visual analog pain scale - VAS) in patients submitted to surgical procedures performed by the thoracic surgery team of the Hospital Santa Marcelina de Itaquera. Evaluate the impacts of PROSM in reducing the costs (US dollars) of surgical treatment and hospitalization of these patients. Materials and methods: A group of 200 patients with elective pulmonary resections (segmentectomies, lobectomies or pneumonectomies) to treat neoplastic lung diseases will be selected by the investigators. The participants will be randomized into two groups (rate of randomization 1/1). The first group will be submitted to the standard surgical treatment that is currently used in Santa Marcelina - Itaquera hospital. The second group will be submitted to treatment with the adoption of the PROSM guidelines, which will be detailed later. Investigators will evaluate in the two groups: surgical time in minutes, intraoperative complications: intraoperative bleeding in mililiters, need for transfusion of blood products, intraoperative clinical complications. Investigators will also evaluate the need for postoperative recovery in Intensive Care Unit (ICU), medications used to maintain the anesthetic plane during the procedure (amount of drugs in milligrams), medications used for postoperative analgesia, length of hospital stay in days, postoperative clinical complications, need for surgical re-boarding, immediate postoperative pain (VAS), postoperative pain at the time of discharge and the first outpatient return (VAS), the need for opioid analgesics at home after discharge. After the data collection, the investigators will analyze them and make a comparative study of the costs of surgical treatment and hospitalization between the two groups. This data will be obtained from the billing department of the Hospital Santa Marcelina de Itaquera.

Assessing Timing of Enteral Feeding Support in Esophageal Cancer Patients on Muscle functTion and Survival

The surgical stress of an esophagectomy causes a detrimental impact on the physiological response of the body. In this perspective, one could question whether the current feeding regimens of starting early nutritional support at postoperative day (POD) 1 have a similar negative impact on the muscle mass as documented in critically ill patients. This study will introduce relative starvation in the early days following esophagectomy compared to the current regimen of early enteral nutritional support. The research team aims to investigate whether the negative impact on muscle mass and muscle function might be reduced, which should result in enhanced postoperative recovery. The final result of the study will be a well-documented and scientifically substantiated nutritional regimen for patients who underwent an esophagectomy for cancer.

Endoscopic Assisted Anterior Hyaloid Peeling in Boston Type 1 Keratoprosthesis (KPro-HP-Endo)

Common complications of the Boston keratoprosthesis type 1 (KPro) surgery include retroprosthetic membrane formation, glaucoma, and retinal detachment. Often pars plana vitrectomy (PPV) is performed at the same time as KPro surgery for different indications. It has been shown to reduce postoperative complications in comparison to when it is performed after the KPro surgery. Patients who receive a complete PPV with peeling of the anterior hyaloid membrane have a lower incidence of retroprosthetic membrane formation and less vision loss due to glaucoma when compared to patients with partial PPV or anterior vitrectomy. During a complete PPV, peeling of the anterior hyaloid membrane is a difficult step because visualisation is poor, but it can be improved using endoscopy. The investigators suggest that peeling of the anterior hyaloid membrane assisted by endoscopy during KPro surgery would decrease postoperative complications in comparison to a PPV done after KPro surgery and without endoscopy.

Management and Outcomes of Perioperative Care Among European Diabetic Patients

The incidence of diabetes is increasing globally, including within Europe. There is an estimated 20million diabetic patients in Europe, which is likely to increase, thereby adding to societal demands on European health services. Diabetic patients are more likely to have surgical interventions than the general population. There are plausible pathophysiology and clinical mechanisms that diabetics are at increased risk of postoperative complications. When postoperative complications occur in the general population, they increase mortality or increase risk of major adverse cardiovascular events (Myocardial Infarction, Cerebrovascular Accident, Pulmonary embolism) at 30-days and up to one year later. In addition, diabetes is an independent risk factor for surgical site infections. There is variation in practice guidelines in different countries in the perioperative management of diabetic patients undergoing major surgery, but this has not been documented on a large scale. Given the multiplicity of guidelines and differing recommendations, it is unsurprising that variability of 'real-world' clinical practice with regard to perioperative management of oral antihyperglycemic medications and insulin therapy has been noted in audits such as the National Confidential Enquiry into Patient Outcome and Death (NCEPOD). Further, although it is recognised that diabetic patients are at increased risk of postoperative complications, this has not been recently evaluated, especially in light of ongoing developments in perioperative care, such as Enhanced Recovery Programmes. While a quality improvement intervention study has shown that maintaining tight preoperative glycaemic control improves postoperative glycaemic control, it is not known if this reduces postoperative morbidity overall. Further, whether certain anaesthetic techniques may be associated with better or worse outcomes after major non-cardiac surgery is unknown.

Frailty and Postoperative Outcomes After Gastric Cancer Surgery

Background. Gastric cancer is an important health care problem even though treatment advances, and it is diagnosed mainly in elderly. Surgery is the main treatment for gastric cancer and is associated with a high rate of postoperative complications and mortality, even higher in older patients. Chronological age seems not to be the main factor influencing the worse outcome of older patients, comorbidities and frailty have also been taken into account recently. Methods. Participation in the study will be offered to all centers that are currently part of the Spanish EURECCA (EUropean REgistry of Cancer CAre) Esophagogastric Cancer Registry. The impact of the frailty on different outcome variables will be evaluated. The main outcome variable will be 90-day mortality after the intervention. Health-Related Quality of Life (HRQoL) will also be evaluated. Objective. The objective of the study is to value the impact of frailty on gastric cancer surgery outcomes therein the Spanish EURECCA Esophagogastric Cancer Registry.

Randomized-controlled Trial of Preoperative Inspiratory Muscle Training on Postoperative Complications

Rehabilitation strategies after abdominal surgery enhance recovery and improve outcome. A cornerstone of rehabilitation is respiratory physiotherapy with inspiratory muscle training to enhance pulmonary function. Prehabilitation is the process of enhancing functional capacity before surgery in order to compensate for the stress of surgery and postoperative recovery. There is growing interest in deploying pre-habilitation interventions prior to surgery. The aim of this study is to assess the impact of preoperative inspiratory muscle training on postoperative overall morbidity. The question is, whether inspiratory muscle training prior to elective abdominal surgery reduces the number of postoperative complications and their severity grade.

Intraoperative Blood Pressure Management and Dexamethasone in Lung Cancer Surgery

Surgery is the front-line therapy for non-small cell lung cancer (NSCLC) but postoperative complications remains high and patients' long-term outcome is still challenging. In addition to surgery, anesthetic management particularly intraoperative blood pressure management and use of dexamethasone may affect patients' early and long-term outcomes after surgery for NSCLC. This study aims to investigate the impact of intraoperative blood pressure management and dexamethasone administration on early and long-term outcomes in patients undergoing surgery for lung cancer.

Suprainguinal Fascia Iliaca Block Versus PENG Block for Hip Arthroplasty Analgesia

In recent years, suprainguinal fascia iliaca block (SFIB) has emerged as a reliable analgesic option for primary total hip arthroplasty (THA). In 2018, a new block was described, termed pericapsular nerve group block or PENG block, that selectively targets the articular branches of the femoral and obturator nerves while sparing their motor components. In this randomized trial, the investigators will compare US-guided SFIB and PENG block in patients undergoing primary THA. Since the main benefit of PENGB stems from its quadriceps-sparing effect, it was selected the incidence of quadriceps motor block (at 6 hours) as the primary outcome and the hypothesis that PENG block will result in significantly less motor block compared to SFIB.
