Factors influencing hospital stay duration in an elective cardiac surgery cohort

Abstract Cardiac surgery has become more complex in recent years, with increases in patient age, complexity, and associated costs. The use of a multidisciplinary strategy to analyze and standardize patient management offers significant benefits. The development of Enhanced Recovery After Surgery (ERAS) programs has proven useful in various types of surgery, recently including cardiac surgery, yielding good results. One of the primary objectives of ERAS programs is the reduction of the Inpatients' length of stay (LOS), with the subsequent improvement in the patient experience and a reduction in costs. The aim of this study is to analyze preoperative and postoperative factors related to the LOS reduction in a cohort of elective cardiac surgery patients included in the Cardiac ERAS program at our hospital. All patients included in the ERAS program, corresponding to elective cardiac surgery, were included in the analysis. 138 patients were divided into four quartiles based on the inpatient’s LOS. An extensive search was conducted in our quality control database, which contains 470 variables on the factors more strongly associated with LOS. The results were analyzed using Chi-Square test for categorical and the Kruskal-Wallis test for continuous variables, generally of non-normal distribution. The results are summarized in the table. Age, poor mobility, surgery other than coronary bypass, and reoperation were the non-modifiable factors most associated with a prolonged LOS. Lower preoperative hemoglobin and albumin levels were associated with an increase in LOS. A class 3 or 4 NYHA functional class, chronic pulmonary disease, and anticoagulation use were associated with higher LOS. Classic cardiovascular risk factors, such as dyslipidemia, hypertension, and tobacco use, were not associated with differences in hospitalization duration. Postoperative and intraoperative factors associated with higher LOS included extubation in the operating room or within six hours, ICU stay duration, mobilization on postoperative days one and two, time to oral food tolerance and gut motility recovery, hyperglycemia on postoperative day one, the duration of arterial, venous, and urinary catheters, the amount of fluids on postoperative day one and the opioid use in POD 2. The complications most associated with a prolonged duration were any infectious complication, any respiratory complication, reoperation, readmission to intensive care, transfusion after 12 hours or at any time during hospitalization, prolonged postoperative sedation, and any rhythmic complication. Conclusion In our cohort of elective patients for cardiac surgery, factors traditionally addressed by ERAS programs were identified as being associated with a longer inpatient’s length of stay. Pre-operative nutritional and anemia optimization, early extubation and mobilization, and the prevention of respiratory and infectious complications should be targeted to improve hospital stay duration.

Increased physiologic dead space fraction is associated with mortality after comprehensive stage 2 operation.

Our objective was to assess the predictive value of physiologic dead space fraction for mortality in patients undergoing the comprehensive stage 2 operation. This was a single-centre retrospective observational study conducted at a quaternary free-standing children's hospital specialising in hybrid palliation of single ventricle cardiac disease. 180 patients underwent the comprehensive stage 2 operation. 76 patients (42%) underwent early extubation, 59 (33%) standard extubation, and 45 (25%) delayed extubation. We measured time to extubation, post-operative outcomes, length of stay and utilised Fine gray models, Youden's J statistic, cumulative incidence function, and logistic regression to analyse outcomes. Delayed extubation group suffered significantly higher rates of mortality (31.1% vs. 6.8%), cardiac arrest (40.0% vs. 10.2%), stroke (37.8% vs. 11.9%), and need for catheter (28.9% vs. 5.1%) and surgical intervention (24.4% vs. 8.5%) (P < 0.001). Physiologic dead space fraction was significantly higher in the delayed extubation group and in non-survivors with a value of 0.3, which was found to be the discriminatory point by Youden's J statistic. For a 0.1 unit increase in physiologic dead space fraction on post-operative day 1, the odds of a patient expiring increase by a factor of 2.26 (95% CI 1.41-3.97, p < 0.001) and by a factor of 3.79 (95% CI 1.65-11.7, p 0.01) on post-operative day 3. Delayed extubation impacts morbidity and mortality in patients undergoing the comprehensive stage 2 operation. Increased physiologic dead space fraction in the first 60 hours after arrival to the ICU is associated with higher mortality.

Proposed Quality Metrics for Congenital Cardiac Anesthesia: A Scoping Review.

Congenital cardiac anesthesiologists practice in a unique environment with high risk for morbidity and mortality. Quality metrics can be used to focus clinical initiatives on evidence-based care and provide a target for local quality improvement measures. However, there has been no comprehensive review on appropriate quality metrics for congenital cardiac anesthesia to date. Members of the Quality and Safety Committee for the Congenital Cardiac Anesthesia Society proposed 31 possible candidate topics for metrics. Using a scoping review strategy, 3649 abstracts were reviewed with 30 articles meeting final criteria. Of these, 5 candidate metrics were unanimously proposed for local collection and national benchmarking efforts: use of a structured handover in the intensive care unit, use of an infection prevention bundle, use of blood conservation strategies, early extubation of cardiopulmonary bypass cases, and cardiac arrest under the care of a cardiac anesthesiologist. Many metrics were excluded due to a lack of primary data and perceived complexity beyond the scope of cardiac anesthesia practice. There is a need to develop more primary data including linking process measures with outcomes, developing risk-stratification for our patients, and collecting national data for benchmarking purposes.

Independent Risk Factors and Economic Burden Associated With Delayed Extubation Following Pediatric Liver Transplantation.

Successful early extubation (EE) after liver transplant (LT) has been shown to reduce intensive care unit (ICU) and hospital length of stay and infectious, vascular, and sedation-related complications in adults. EE may not always be feasible in children, and many may require prolonged mechanical ventilation. Limited data exists regarding the candidacy of EE, risk factors, consequences, and hospital costs of delayed extubation (DE) in pediatric LT. We conducted a retrospective review to investigate predictive factors and associated costs of EE and DE in infants and children after orthotopic LT at our institution between 2011 and 2021. Of 338 LT (median age 39 months, 54% females), 246 (73%) had EE (within 24 h of LT), while 27% had DE. Age < 1 year (p = 0.0019), diagnosis of biliary atresia (0.02), abnormal pre-LT echocardiogram (0.02), and patients with ongoing hospital admission before LT (0.0001) were independently associated with DE. Hospital costs were significantly (∼3-fold) higher (p < 0.0001) in the DE group. In addition, factors associated with increased total hospital costs were age < 1 year and hospitalization before LT. EE post-LT is feasible and merits a trial. The prevalence of DE though modest is associated with increased resource utilization and hospital costs. Children who can be extubated early and those at risk for DE can be identified pre-operatively for optimal planning and allocation of resources.

A Retrospective Multicenter Study of Operating Room Extubation and Extubation Timing following Cardiac Surgery

BackgroundIn an effort to enhance recovery after cardiac surgery, intraoperative extubation has been targeted as possibly beneficial. This multi-center cohort study aimed to assess this by evaluating the outcomes of OR extubation versus extubation within six hours of intensive care unit arrival (early ICU extubation). Furthermore, we assessed time to ICU extubation and mortality and morbidity. MethodsPatients undergoing on-pump cardiac surgery across 79 hospitals between 2011-2020 were included to 1) compare outcomes among OR extubation and early ICU extubation patients, and 2) assess time to overall ICU extubation and outcomes. ResultsThe overall study cohort comprised 163,982 patients, including 95,982 patients [ [ OR extubation : n= 2,529 (2.6%)and early ICU extubation : n= 93,453 (97.4%)] who underwent comparison of OR with early ICU extubation. Following overlap weighting, OR extubation patients had longer OR times (5.6 vs. 5.1 hours, p < 0.0001), and higher rates of reintubation (5.2% vs 2.9%, p=0.003), prolonged ventilation (3% vs 2%, p = 0.021), reoperation for bleeding (1.5% vs 0.7%, p < 0,01), pneumonia (1.9% vs. 1.1% , p < 0.006), and greater in-hospital mortality on multivariable regression (OR 1.34, p < 0.001). OR extubation patients at centers with low OR extubation rates (< 10%, N=60) had higher mortality (odds ratio 1.6, p = 0.001). Beyond 22 hours of postoperative ICU ventilation, the risk of morbidity and mortality increased significantly . ConclusionsFew cardiac surgery patients are extubated in the OR, which is associated with no clinical benefit and with increased morbidity. Cardiac surgery programs should reconsider OR extubation following cardiopulmonary bypass. Additionally, increased intubation time, in particular > 22 hours, is associated with an increase in adverse outcomes.

Exploring Anesthesiology Management of Living Donor Liver Transplantation: Survey From the Society for the Advancement of Transplant Anesthesia and the Korean Society for Transplantation Anesthesiologists.

While living donor liver transplantation (LDLT) serves as the predominant method of adult liver transplant (LT) in the Republic of Korea (ROK), it represents a minority of LT in the United States (US). A survey was conducted to gain insight into these nations' anesthetic management. An electronic questionnaire was distributed to directors of LT anesthesiology overseeing LDLT programs in both countries between May 2021 and October 2021. The response rate was 93.0% (100% [37/37] in the US and 80% [16/20] in the ROK). Both countries mainly adhered to deceased donor LT recipient management practices, including the frequency of routine pulmonary artery catheter use, transesophageal echocardiography, and point-of-care coagulation monitoring. Differences were observed in early extubation of recipients (US vs. ROK: 39.7%vs. 14.7% of all cases), participation in donor selection meetings (88.9% [32/36] vs. 6.3% [1/16], p < 0.0001), application of the Enhanced Recovery After Surgery donor protocol (69.4% [25/36] vs. 12.5% [2/16], p < 0.0001), and cell saver usage for donors (94.4% [34/36] vs. 18.8% [3/16], p < 0.0001). More ROK programs implemented simultaneous donor/recipient anesthesia supervision by a single anesthesiologist. Several important differences were identified between the US and the ROK in adult LDLT anesthetic management.

Fast-Track Score to Predict the Feasibility of Early Extubation Post Liver Transplant

Background Over the past several years, the liver transplant community has embraced the concept of fast-tracking patients to facilitate earlier postoperative recovery. Aim Derive and validate a novel “fast-track” risk score that captures the demographic and clinical characteristics of DDLT patients to predict the likelihood of early extubation after surgery. Design Adult patients who underwent non-fulminant DDLT between January 2014 and July 2019 were included. The cohort was divided in 2 groups: patients extubated within 4 hours of surgery vs extubated after 4 h. Logistic regression was performed to identify the independent predictors of early extubation. The area under the curve (AUC) was calculated to measure the ability of the risk score to predict early extubation. The score was validated by applying coefficients of the regression model to the validation cohort and calculating the AUC. Results A total of 290 DDLT patients were included, of which 175 (60%) were in the “delayed extubation” group and 115 (40%) were in the “fast-track” group. Patients with a MELD &lt;29, transfused &lt;4 units of pRBCs, and transfused &lt;5 units of FFP during surgery were 2.30 times, 5.74 times, and 3.09 times more likely to be extubated early, respectively. A risk score with an integer point scale was derived and exhibited an AUC of .80. The proportion of patients who were extubated early increased from 2.78% at a score of 0 to 66.67% at a score of 4. Conclusions The proposed score provides a fast and easy method to help identify DDLT patients suitable for early extubation.

Minimally invasive technique facilitates early extubation after cardiac surgery: a single-center retrospective study

BackgroundPostoperative time to extubation plays a role in prognosis after heart valve surgery; however, its exact impact has not been clarified. This study compared the postoperative outcomes of minimally invasive surgery and conventional sternotomy, focusing on early extubation and factors influencing prolonged mechanical ventilation.MethodsData from 744 patients who underwent heart valve surgery at the Zhejiang Provincial People’s Hospital between August 2019 and June 2022 were retrospectively analyzed. The outcomes in patients who underwent conventional median sternotomy (MS) and minimally invasive (MI) video-assisted thoracoscopic surgery were compared using inverse probability of treatment weighting (IPTW) and Kaplan–Meier curves. Clinical data, including surgical data, postoperative cardiac function, postoperative complications, and intensive care monitoring data, were analyzed.ResultsAfter propensity score matching and IPTW, 196 cases of conventional MS were compared with 196 cases of MI video-assisted thoracoscopic surgery. Compared to patients in the conventional MS group, those in the MI video-assisted thoracoscopic surgery group in the matched cohort had a higher early postoperative extubation rate (P < 0.01), reduced incidence of postoperative pleural effusion (P < 0.05), significantly shorter length of stay in the intensive care unit (P < 0.01), shorter overall length of hospital stay (P < 0.01), and lower total cost of hospitalization (P < 0.01).ConclusionsSuccessful early tracheal extubation is important for the intensive care management of patients after heart valve surgery. The advantages of MI video-assisted thoracoscopic surgery over conventional MS include significant reductions in the duration of use of mechanical ventilation support, reduced length of intensive care unit stay, reduced total length of hospitalization, and a favorable patient recovery rate.

Effect on post-operative pulmonary complications frequency of high flow nasal oxygen versus standard oxygen therapy in patients undergoing esophagectomy for cancer: study protocol for a randomized controlled trial-OSSIGENA study.

Postoperative pulmonary complications (PPCs) remain a challenge after esophagectomy. Despite improvement in surgical and anesthesiological management, PPCs are reported in as many as 40% of patients. The main aim of this study is to investigate whether early application of high-flow nasal cannula (HFNC) after extubation will provide benefit in terms of reduced PPC frequency compared to standard oxygen therapy. Patients aged 18-85 years undergoing esophagectomy for cancer treatment with radical intent, excluding those with American Society of Anesthesiologists (ASA) score >3 and severe systemic comorbidity (cardiac, pulmonary, renal or hepatic disease) will be randomized at the end of surgery to receive HFNC or standard oxygen therapy (Venturi mask or nasal goggles) after early extubation (within 12 hours after the end of surgery) for 48 hours. The main postoperative goals are to obtain SpO2 ≥94% and adequate pain control. Oxygen therapy after 48 hours will be stopped unless the physician deems it necessary. In case of respiratory clinical worsening, patients will be supported with the most appropriate tool (noninvasive ventilation or invasive mechanical ventilation). Pulmonary [pneumonia, pleural effusion, pneumothorax, atelectasis, acute respiratory distress syndrome (ARDS), tracheo-bronchial injury, air leak, reintubation, and/or respiratory failure] complications will be recorded as main outcome. Secondary outcomes, including cardiovascular, surgical, renal and infective complications will also be recorded. The primary analysis will be carried out on 320 patients (160 per group) and performed on an intention-to-treat (ITT) basis, including all participants randomized into the treatment groups, regardless of protocol adherence. The primary outcome, the PPC rate, will be compared between the two treatment groups using a chi-square test for categorical data, or Fisher's exact test will be used if the assumptions for the chi-square test are not met. Recent evidence demonstrated that early application of HFNC improved the respiratory rate oxygenation index (ROX index) after esophagectomy but did not reduce PPCs. This randomized controlled multicenter trial aims to assess the potential effect of the application of HFNC versus standard oxygen over PPCs in patients undergoing esophagectomy. This study is registered at clinicaltrial.gov NCT05718284, dated 30 January 2023.

Early extubation after elective surgical aortic valve replacement during the COVID-19 pandemic

BackgroundSurgical aortic valve replacement (SAVR) is an established therapy for severe calcific aortic stenosis. Enhanced recovery after cardiac surgery (ERACS) protocols have been shown to improve outcomes for elective cardiac procedures. The COVID-19 pandemic prompted early extubation post-elective surgeries to preserve critical care resources.Aim of this studyTo investigate the effects of extubating patients within 6 h post-elective SAVR on hospital and ICU length of stay, mortality rates, ICU readmissions, and postoperative pneumonia.Study Design and methodsThe retrospective analysis at the University Hospital Aachen, Germany, includes data from 2017 to 2022 and compares a total of 73 elective SAVR patients. Among these, 23 patients were extubated within 6 h (EXT group), while 50 patients remained intubated for over 6 h (INT group).ResultsThe INT group experienced longer postoperative ventilation, needed more vasopressor support, had a higher incidence of postoperative pneumonia, and longer ICU length of stay. No significant differences were noted in overall hospital length of stay, mortality, or ICU readmission rates between the groups.ConclusionThis study demonstrates that early extubation in high-risk, multimorbid surgical aortic valve replacement patients is safe, and is associated with a reduction of pneumonia rates, and with shorter ICU and hospital length of stays, reinforcing the benefits of ERACS protocols, especially critical during the COVID-19 pandemic to optimize intensive care use.

Reducing Hospital Length of Stay and Hepatic Artery Thrombosis Rates for Children Receiving a Liver Transplant: A Single-Center Experience From 2000 to 2021.

Pediatric liver transplantation is a very resource-intensive therapy. This study aimed to identify the changes made between two epochs of management and analyze their influence on length of stay (LOS). Data from a single center were obtained from the liver transplant and Pediatric Intensive Care Unit (PICU) databases for 336 transplants (282 children) performed between 2000 and 2021. Transplants were analyzed in two epochs, before and after July 2012, representing a change in postoperative anticoagulation management. Differences in graft recipient demographics and perioperative management factors were compared between epochs. Multivariate regression was performed to identify the complications that correlated most strongly with hospital LOS. There was a difference in hospital LOS between Epoch 1 (Median = 31.7 days) and Epoch 2 (Median = 26.3 days) (p < 0.001), but not in PICU LOS (E1 Median = 7.3 days, E2 Median = 7.4 days; p = 0.792). Epoch 2 saw increased use of split grafts (60.6% of total), decreased pediatric end-stage liver disease (PELD) score at transplant (Average = 16.7; p < 0.001), decreased invasive ventilation time (Average = 4.48 days; p < 0.001), and decreased hepatic artery thrombosis (HAT) rates (E1 = 14.4%, E2 = 4.3%; p < 0.001) without an associated increase in bleeding rates. Hospital LOS has reduced in Epoch 2 due to refinements in intraoperative and postoperative management. There is increased emphasis on early extubation and increased use of noninvasive ventilatory techniques in Epoch 2. Split grafts have effectively expanded our graft donor pool and reduced transplant waitlist times.

Posttraumatic hydrocephalus as a complication of decompressive craniectomy-same old story, new perspectives.

Decompressive craniectomy (DC) serves as a vital life-saving intervention, demonstrating efficacy in reducing intracranial pressure (ICP). However, its efficacy hinges on meticulous surgical execution, perioperative management, and vigilance toward potential complications. The incidence of complications associated with DC plays a pivotal role in determining its superiority over medical management for patients experiencing intracranial hypertension following traumatic brain injury (TBI). Severe cases often require more intensive therapy, prolonged mechanical ventilation, and vasopressor treatment. Identifying the optimal moment for early extubation and minimizing vasopressor use is crucial to reducing the risk of complications, including PTH. Our study aims to highlight the potential risks associated with prolonged mechanical ventilation and long-term vasopressor administration. The collected data were demographics, the craniectomy size, the distance from the midline of the craniectomy, the presence or absence of hydrocephalus, duration of mechanical ventilation and vasopressor treatment, and outcome at 30 days. Seventy-two patients with a mean age of 44.2 (range 5-83) were included in the study, with a median craniectomy size of 119.3 cm2. In our series, craniectomy areas ranged between 30 and 207.5 cm2 and had a similar decrease in midline shift in all cases. We did not observe any associations between the surface of craniectomy and the complication rate (p = 0.6302). There was no association between craniectomy size and mortality rate or length of hospital stay. The most common complication of decompressive craniectomy in our study group was posttraumatic hydrocephalus, with an incidence of 13.8%. Our results showed that craniectomy size did not independently affect PTH development (p = 0.5125). Still, there was a strong correlation between prolonged time of vasopressor treatment (p = 0.01843), period of mechanical ventilation (p = 0.04928), and the development of PTH. This study suggests that there is no clear correlation between craniectomy size, midline shift reduction, and survival rate. An extended period of vasopressor treatment or mechanical ventilation is linked with the development of posttraumatic hydrocephalus. Further studies on larger series or randomized controlled studies are needed to better define this correlation.

Optic nerve elongation during fronto-facial surgery for Crouzon syndrome: 3D quantification and clinical implications.

Fronto-facial monobloc advancement with internal distraction (FFMBA) is a key procedure in the management of syndromic craniosynostoses. FFMBA involves circumferential dissection and linear enlargement of the orbit, potentially leading to mechanical stress on the optic nerve (ON). Several reports of transient vision loss during the distraction process led us to investigate ON shape modifications during facial advancement, with the aim to potentially refine current clinical guidelines on postoperative management and the distraction schedule. Twenty-six patients with Crouzon syndrome were included in this study. ONs were segmented on pre- and postoperative CT scans. Distraction amplitudes, linear and curved lengths, and cross-section diameters of the ON were assessed along the main axis of the nerve. A two-level hierarchical multivariate linear model was used to screen for factors associated with ON morphology. The mean age at FFMBA was 4.4 ± 3.8 years. Two patients presented with transient impaired vision during distraction. The final mean fronto-orbital and temporo-zygomatic distraction amplitudes were 18 ± 4 mm and 18 ± 6 mm, respectively. At the end of distraction, ONs were elongated (+1.8 mm for curved lengths, p = 0.013), and their mean cross-section was reduced (-1.9 mm2, p < 0.001) in the proximal intraorbital portion (first 15 mm). In the 2 patients with visual symptoms, functional impairment was associated with ON area reduction (OR 0.487, p < 0.001) and increased temporo-zygomatic distraction amplitude (OR 2.240, p < 0.001). ON was elongated during FFMBA, with proximal diameter reduction. Transient visual impairment with normal fundus examination during distraction seemed to have a morphological basis, based on 2 cases. These results suggest the importance of vision monitoring associated with fundus examination during distraction, and advocate for early extubation after FFMBA to allow clinical follow-up.

Early extubation after pediatric cardiac surgery.

Early extubation after pediatric cardiac surgery has come full circle from being practiced in the early days of pediatric cardiac surgery, falling out of favor with opioid-heavy cardiostable anesthesia, and resurfacing again in more recent times as part of enhanced recovery after surgery practice. Early extubation is variably defined, but is mostly accepted as extubation that occurs within 6-8 h from the end of surgery. In recent years, the debate has shifted from early extubation in the intensive care unit to immediate extubation in the operating theatre. In this review, we examined the benefits and pitfalls of early and immediate extubation, factors that influence the success of early extubation, and potential guidelines for practice and implementation.

The Complex Interplay of Variables in Extubation Decision-Making Following Pediatric Cardiac Surgery: A Narrative Review.

Pediatric cardiac surgery poses significant challenges in developing countries, where a considerable number of children require intervention for congenital heart disease (CHD). The utilization of endotracheal intubation and anesthesia is pivotal in conducting surgical or angiography procedures on patients with CHD exhibiting diverse anatomical and hemodynamic characteristics. The decision to extubate pediatric patients following cardiac surgery remains a crucial element of postoperative care. This article explores the complexities surrounding extubation decision-making in this population, emphasizing the critical role of surgical, physiological, and postoperative factors. Various preoperative and intraoperative factors influence the timing of extubation. Early extubation is increasingly prevalent, offering benefits like reduced length of stay and minimized drug exposure. Multidisciplinary collaboration and protocol-driven strategies contribute to improved extubation outcomes, emphasizing the need for a comprehensive approach in pediatric cardiac surgery. Future research can focus on the implementation and efficacy of standardized extubation procedures involving collaboration among healthcare experts.

Anesthesia for Minimal Invasive Cardiac Surgery: The Bonn Heart Center Protocol.

The development and adoption of minimally invasive techniques has revolutionized various surgical disciplines and has also been introduced into cardiac surgery, offering patients less invasive options with reduced trauma and faster recovery time compared to traditional open-heart procedures with sternotomy. This article provides a comprehensive overview of the anesthesiologic management for minimally invasive cardiac surgery (MICS), focusing on preoperative assessment, intraoperative anesthesia techniques, and postoperative care protocols. Anesthesia induction and airway management strategies are tailored to each patient's needs, with meticulous attention to maintaining hemodynamic stability and ensuring adequate ventilation. Intraoperative monitoring, including transesophageal echocardiography (TEE), processed EEG monitoring, and near-infrared spectroscopy (NIRS), facilitates real-time assessment of cardiac and cerebral perfusion, as well as function, optimizing patient safety and improving outcomes. The peripheral cannulation techniques for cardiopulmonary bypass (CPB) initiation are described, highlighting the importance of cannula placement to minimize tissue as well as vessel trauma and optimize perfusion. This article also discusses specific MICS procedures, detailing anesthetic considerations and surgical techniques. The perioperative care of patients undergoing MICS requires a multidisciplinary approach including surgeons, perfusionists, and anesthesiologists adhering to standardized treatment protocols and pathways. By leveraging advanced monitoring techniques and tailored anesthetic protocols, clinicians can optimize patient outcomes and promote early extubation and enhanced recovery.

Peri-Operative Use of Ketamine Infusion versus Dexmedetomidine Infusion for Analgesia in Obese Patients Undergoing Bariatric Surgery: A Double-Blinded Three-Armed Randomized Controlled Trial

Abstract Background The development of different techniques in bariatric surgeries has required the development of novel anesthetic techniques to reduce the incidence of complications and improve post-operative patient outcomes. Ketamine and dexmedetomidine have been used for their peri-operative analgesic profiles in different studies. Methods Ninety patients were studied and randomized equally into three groups. The Ketamine group received a bolus dose (0.3 mg/kg) of ketamine over 10 min followed by an infusion (0.3 mg/kg/h). The Dexmedetomidine group received a bolus dose (0.5 mcg/kg) of dexmedetomidine over 10 min followed by an infusion (0.5 mcg/kg/h). The control group received normal saline infusion. The total morphine dose was the primary outcome, and intra-operative fentanyl requirements, time to extubation, post-operative nausea and vomiting (PONV), Numerical Rating Scale (NRS) scores, and Modified Observer’s Agitation/Sedation Scale (MOASS) scores were secondary outcomes of the study. Results The Dexmedetomidine group showed decreased intra-operative fentanyl requirements (160.000 ± 42.345 µcg), less time to extubation (3.700 ± 0.925 min), and better scores on MOASS than the other groups. Post-operative NRS scores and the morphine requirement in the Ketamine group (1.867 ± 2.921 mg) were lower than in the other groups. The Dexmedetomidine group showed the lowest scores for PONV. Conclusions The Dexmedetomidine group showed lower total fentanyl doses, a significantly shorter time to extubation, better MOASS scores, and lower PONV. The Ketamine group showed significantly lower NRS scores and morphine doses than the other two groups. Dexmedetomidine was effective on the reduction of intraoperative fentanyl requirement with early extubation, and ketamine was effective on the reduction of postoperative pain. Trial Registration This trial has been registered on clinicaltrials.gov registry (NCT04576975) since 06/10/2020.

Screening of Palatopharyngeal Incoordination in Mechanically Ventilated Critically Ill Infants

Abstract Background Palatopharyngeal incoordination is a common phenomenon in patients requiring endotracheal intubation for mechanical ventilation. Understanding the underlying mechanism of palatopharyngeal incoordination may help as a screening tool that improves rates of early recognition and diagnosis and the ability to take preventive measures essential to alleviate related morbidity and complications. Objective The aim of this study is to screen palatopharyngeal incoordination in infants who needed mechanical ventilation and to elicit palatopharyngeal incoordination secondary to mechanical ventilation. Material and Methods This study included 51 patients at the Pediatric Intensive Care Unit, Faculty of Medicine, Ain Shams University, The study was conducted during the period from February 2021 to February 2022. patients were classified according to a Fiberoptic Flexible Endoscopic Evaluation of Swallowing (FEES) early post intubation, FEES early post extubation, Videofluoroscopic Swallow Study (VFSS) post extubation and dye study into five groups: group (1) the not affected group, group (2) the palatopharyngeal incoordination group, group (3) The palatopharyngeal incoordination with gastro esophageal reflux group, group (4) The reflux group, group (5) The congenital upper air way anomalies group in which patients were ventilated due to respiratory distress. Follow up FEES and VFSS were done after three months for palatopharyngeal incoordination patients. Results Palatopharyngeal incoordination was detected in 16 patients (31.3%), congenital upper airway anomalies were found in 12 patients (23.5%), and gastroesophageal reflux was only detected in 10 patients (19.6%). Performing VFSS and FEES after three months showed 92.3 % of palatopharyngeal incoordination patients had resolved palatopharyngeal incoordination and 7.7 % of palatopharyngeal incoordination patients had silent aspiration. Conclusion The prevalence of palatopharyngeal incoordination is 31.3 % and there was no palatopharyngeal incoordination secondary to mechanical ventilation.

Intraoperative Dexmedetomidine Use for Enhanced Recovery after Surgery (ERAS) in Cardiac Surgery-Single Center Retrospective Observational Cohort Study.

Background and Objectives: Dexmedetomidine, an alpha-2 agonist, is used as an adjunct to anesthesia in enhanced recovery after surgery (ERAS) programs. One of its advantages is the opioid-sparing effect which can facilitate early extubation and recovery. When the ERAS cardiac society was set in 2017, our facility was already using the ERAS program, in which the "fast-track Anesthesia" was facilitated by the intraoperative infusion of dexmedetomidine. Our objective is to share our experience and investigate the potential impact of intraoperative dexmedetomidine use as a part of the ERAS program on patient outcomes in elective cardiac surgery. Materials and Methods: An observational retrospective cohort study was conducted at a university hospital in Switzerland. The patients who underwent elective cardiac surgery with cardiopulmonary bypass between 1 June 2017 and 31 August 2018 were included in this analysis (n = 327). Regardless of the surgery type, all the patients received a standardized fast-track anesthesia protocol inclusive of dexmedetomidine infusion, reduced opioid dose, and parasternal nerve block. The primary outcome was the postoperative time when the criteria for extubation were met. Three groups were identified: group 0-(extubated in the operating room), group < 6 (extubated in less than 6 h), and group > 6 (extubated in >6 h). The secondary outcomes were adverse events, length of stay in ICU and in hospital, and total hospitalization costs. Results: Dexmedetomidine was well-tolerated, with no significant adverse events reported. Early extubation was performed in 187 patients (57%). Group 3 had a significantly longer length of stay in the ICU (median: 70 h vs. 25 h) and in hospital (17 vs. 12 days), and consequently higher total hospitalization costs (CHF 62,551 vs. 38,433) compared to the net data from the other two groups (p < 0.0001). Conclusions: Our findings suggest that dexmedetomidine can be safely used as part of the opioid-sparing anesthesia protocol in patients undergoing elective cardiac surgery with cardiopulmonary bypass with the potential to facilitate early extubation, shorter ICU and hospital stays, and reduced hospitalization costs.

Development of an evidence-based nursing practice program for preventing unplanned endotracheal extubations in the intensive care unit: A Delphi method study.

This study aims to develop an evidence-based nursing practice program to prevent unplanned endotracheal extubation (UEE) among adult patients in the intensive care unit (ICU). This study uses the Delphi method to develop an evidence-based nursing practice program. A comprehensive review of 18 databases and evidence-based websites was conducted to gather, assess and synthesize evidence on preventing UEEs in adult patients. Using this synthesized evidence, a questionnaire was formulated for further investigation. Subsequently, input was solicited from experts through Delphi surveys to establish an evidence-based nursing practice protocol for preventing UEEs in adult ICU patients. Consistency in consultation results guided subsequent rounds of consultation. The developed program comprised 43 evidence items categorized into nine dimensions, including risk assessment for unplanned extubation, sedation, analgesia, delirium, balloon management, psychosocial care, early extubation, catheter immobilization and protective restraints. Two rounds of expert inquiry yielded recovery rates of 94.7% and 100% for the first and second questionnaires, respectively. Kendall W values ranged from .224 to .353 (p < .001). This study developed an evidence-based nursing practice program to prevent UEE in adult ICU patients, employing evidence-based practices and Delphi expert consultation methods. However, further validation of the program's effectiveness is warranted. Findings were reported according to the Standards for Reporting Qualitative Research checklist. Nurses contributed to the study by participating in investigations. The program developed in this study offers an evidence-based framework for preventing unplanned extubation in hospitals, thereby reducing its incidence and enhancing the quality of nursing care.
