Ambulatory buccal mucosal graft urethroplasty in geriatric population: A practice change experience

ABSTRACT Context: Due to the overwhelming burden of coronavirus disease 2019, buccal mucosal graft (BMG) urethroplasty in the elderly has been shifted from inpatient to ambulatory at our center in early 2020. Aim: This study aims to describe our experience with ambulatory BMG urethroplasty in the elderly and compare its feasibility and safety to inpatient urethroplasty before and after the practice change. Setting and Design: A pre and postpractice change retrospective cohort study of patients aged 65 years or above with BMG urethroplasty performed at our center between March 2018 and May 2022. Materials and Methods: Demographics, clinical characteristics, postoperative course, and complications were compared in ambulatory (discharged within 6 h) versus inpatient BMG urethroplasty groups. Statistical Analysis: A pre-and post-practice change retrospective cohort study of patients aged 65 or older with BMG urethroplasty performed at our centre between March 2018 and May 2022. Results: Of 37 BMG urethroplasties, 15 (40.5%) were inpatient, whereas 22 (59.5%) were ambulatory. Immediate complication rate was comparable in inpatient (2/15, 13.3%) and ambulatory cases (1/22, 4.5%): one wound infection in both groups and one recurrent urinary tract infection in the inpatient group. No oral cavity complications, bleeding/hematoma, or anesthesia-related morbidity were observed. There was no statistically significant difference in recurrence (13.3% vs. 9.6%; P = 0.98) and success rates (90.9% vs. 86.7%; P = 0.53) over a median of 53 (inpatient) and 34 (ambulatory) months follow-up. Conclusions: Ambulatory BMG urethroplasty, discharge within 6 hours of surgery, appears safe and feasible in geriatric populations (>65), with no increased adverse outcomes. Factors like healthcare access, caregiver availability, and patient education play roles in discharge time. However, more robust studies are warranted for conclusive evidence.

Incidence of complications after nonoperating room anesthesia in children in a low- and middle-income country: A prospective and observational study.

Nonoperating room anesthesia is a growing field of medicine that can have an increased risk of complications, particularly in low- and middle-income countries. The aim of this study was to describe the incidence of complications after pediatric nonoperating room anesthesia and investigate its risk factors. In this prospective observational study, we included all children aged less than 5 years who were sedated or anesthetized in the radiology setting of a university hospital in a low- and middle-income country. Patients were divided into two groups: complications or no-complications groups. Then, we compared both groups, and univariable and multivariable logistic regression models were used to investigate the main risk factors for complications. We included 256 children, and the incidence of complications was 8.6%. The main predictors of nonoperating room anesthesia-related morbidity were: critically-ill children (aOR = 2.490; 95% CI: 1.55-11.21), predicted difficult airway (aOR = 5.704; 95% CI: 1.017-31.98), and organization insufficiencies (aOR = 52.6; 95% CI:4.55-613). The preanesthetic consultation few days before NORA protected against complications (aOR = 0.263; 95%CI: 0.080-0.867). The incidence of complications during NORA among children in our radiology setting remains high. Investigating predictors for morbidity allowed high-risk patient selection, which allowed taking precautions. Several improvement measures were taken to address the organization's insufficiencies.

Anaesthesia-related morbidity associated with recumbent, low-field magnetic resonance imaging of horses

ABSTRACT Case history: Medical records from 2009 to 2021 from a private equine referral hospital in Rochester, NH, USA were analysed for cases that underwent general anaesthesia for low-field MRI of the distal limb. These were used to determine peri-anaesthetic morbidity and mortality. Clinical findings and outcome: Two hundred and forty-three anaesthetic episodes were recorded in horses undergoing low-field MRI. The peri-anaesthetic complication rate prior to discharge was 6.2% (15/243). No patients experienced a fatal complication. Ninety two of the 243 patients had multiple sites imaged, 90/243 received pre-anaesthetic dantrolene, 134/243 received intra-anaesthetic dobutamine, and 15/243 were positioned in dorsal recumbency. Complications included: abdominal discomfort (“colic”; 9/243), myopathy (4/243), hyphaema (1/243) and carpal fracture (1/243). At the time of discharge, 14/15 complications had resolved. Of 135 horses for which data were available 55 became hypotensive during the procedure (lowest mean arterial pressure < 65 mmHg). Median body weight was 553 (min 363, max 771) kg. Horses were anaesthetised for a median of 150 (min 45, max 210) minutes. There was no evidence of an association between higher body weight (p = 0.051) or longer duration of anaesthesia (p = 0.421) and development of an anaesthetic complication. For categorical variables (dantrolene administration pre-anaesthesia, dobutamine administration during anaesthesia, hypotension (mean < 65 mmHg) during anaesthesia, dorsal vs. lateral recumbency, and imaging of single vs. multiple sites), the 95% CI for the OR included 1, indicating a lack of effect of the variable on the odds of complication. Clinical relevance: The cases included in this series suggest that low-field MRI under general anaesthesia is a viable option for diagnostic imaging in otherwise healthy horses. Complications occur, but most resolve before discharge.

A survey of United States obstetric anesthesiologists’ perceived value of obstetric anesthesiology fellowship

IntroductionSubspecialty training in obstetric anesthesiology is associated with improved patient outcomes and reduced anesthesia-related morbidity and mortality. Despite this, the demand for fellowship-trained obstetric anesthesiologists far exceeds the supply. This survey study aimed to evaluate the perceived value of obstetric anesthesiology subspecialty training on career trajectory, job satisfaction, quality of life, and job autonomy. MethodsAfter Institutional Review Board approval, we conducted a cross-sectional study of fellowship-trained obstetric anesthesiologists in the United States of America. In March and April 2022, program directors of obstetric anesthesiology fellowships distributed an electronic survey link containing 29 multiple-choice questions to their program alumni. Survey content included respondent demographic characteristics, practice models, career information, and perceived value of an obstetric anesthesiology fellowship. ResultsWe surveyed 217/502 (43%) fellowship-trained obstetric anesthesiologists with a response rate of 158/217 (73%). Most worked in urban, academic, and level IV perinatal health centers. The majority believed an obstetric anesthesiology fellowship was “extremely beneficial” (77%), enhanced quality of life (84%), improved the quality of patient care (99%), and was influential in helping obtain their first post-training job (86%). The perceived value of the fellowship included an enhanced career trajectory, a sense of purpose, improved job satisfaction, a sense of work community, lower burnout, involvement in maternal health initiatives, increased mentorship, and departmental leadership. ConclusionIn this survey study, fellowship-trained obstetric anesthesiologists perceived a positive impact of fellowship training on career trajectory, job protection and autonomy, quality of life, and job satisfaction. This information may be meaningful to trainees considering pursuing a fellowship and a career in obstetric anesthesiology.

Regional anesthesia for geriatric population.

Advancements in modern health care over 20 years have substantially increased the average lifespan in developed countries, and the fastest growing population is the elderly population. The proportion of people in Saudi Arabia aged 60 or more is predicted to be 25 percent of the total population of 40 million by the end of 2050. Moreover, the number of people aged 80 or more is expected to reach 1.6 million or 4 percent of the total population in the same period. Improvements in surgical techniques, anesthesia, and intensive care units make surgical interventions in older and sicker patients possible. It is estimated that over half of the population older than 65 years will require surgical intervention at least once during the remainder of their lives. Therefore, elderly patients are becoming an even larger part of anesthetic practice. Regional anesthesia (RA) is frequently used in elderly patients, especially during orthopedic surgery, genitourologic and gynecologic procedures, and hernia repair. Although age can no longer be considered a contraindication to anesthesia and surgery, anesthesia-related morbidity and mortality remain higher among elderly than among young adult surgical patients. Undoubtedly, peripheral nerve (PN) blocks improve analgesia and reduce opioid consumption and their associated side effects. This is beneficial in the perioperative care of elderly patients who may have less physiologic reserve to withstand the side effects of general anesthesia (GA).

Assessment of preoperative preventive measures for pulmonary aspiration in surgical patients: A cross-sectional study

BackgroundPulmonary aspiration of gastric contents is a rare but catastrophic cause of anesthesia related morbidity and mortality of surgical patients. The risk of pulmonary aspiration is high in surgical patient due to multiple factors. The aim of this study was to assess the practice of aspiration prevention and prophylaxis usage for patients prior to surgery. MethodA cross-sectional study was conducted from 10 April 2022 to 20 April 2022. Data were collected by the direct observation and patient interview. The standards were directly changed in to questionnaire form with two integral components ‘yes’ and ‘no”. Data were entered and analyzed using statistical package of social sciences (SPSS) version 20. ResultA total of 200 surgical patients were included with a response rate of 100%. Preoperative information provision to elective surgical patients on fasting requirements and the reason for them in advance of their procedures was implemented in 63% of the patients. The verification of fasting requirement was provided in 94% of elective patients. About 62.5% of elective surgical patients received gastrointestinal stimulants preoperatively. Metoclopromide was administered for 94% of emergency patients. Conclusion and recommendationThe practice of preoperative fasting and administration of prophylactic agents for pulmonary aspiration is quite limited in our setup. Moreover, adherence to the recommendations of American Society of Anesthesiologist (ASA) and European Society of Anesthesiologist (ESA) was also suboptimal. We strongly recommend clinicians to use appropriate prophylactic agent to the right patient and adherence of the clinician to the local guideline on prevention of pulmonary aspiration.

A Prospective Comparison of Insertion Characteristics of Laryngeal Mask Airway (LMA) ProSeal® Using Rotation Techniques vs Standard Techniques in Adults Undergoing Elective Surgery.

Airway management is the most essential skill in Anesthesiology and the inability to secure the airway is one of the most common reasons for anesthesia-related morbidity and mortality. This study aimed to evaluate and compare the insertion characteristics of laryngeal mask airway (LMA)ProSeal insertion using the standard introducer technique, 90-degree rotation technique, and 180-degree rotation technique in adult patients undergoing elective surgery. This prospective, interventional, randomized, comparative study was carried out in the Department of Anesthesia and Intensive Care, Vardhman Mahavir Medical College & Safdarjung Hospital, New Delhi, after obtaining hospital ethical committee approval for 18 months of duration. Patients in the age group 18-65 years, of either gender, fulfilling American Society of Anesthesiologists grade I or II criteria, scheduled for elective surgery under general anesthesia with controlled ventilation using the LMA ProSeal were included in the study. The patients were randomized into three groups: Group I - Standard Introducer technique (n=40); Group NR - 90-degree rotation technique (n=40); Group RR - 180-degree rotation technique or back to front (airway) technique (n=40). In this study, the majority (73.3%) of the patients were females with 31 patients in group I, 29 patients in group NR, and 28 patients in group RR. A total of 26.67% of male patients were included in the study. No significant difference in the gender distribution of the three groups was seen in the study. There was no incidence of failure in ProSeal laryngeal mask airway (PLMA) insertion in the NR group, while it was 2.50% in group I and 7.50% in group RR but the difference was not statistically significant. A statistically significant difference was seen in the incidence of LMA ProSeal blood staining (p=0.013). In the post-anesthesia care unit at 1 hour, the incidence of sore throat was 10% in patients with the NR group, 30% in the I group, and 35.44% in the RR group which was statistically significant. The study concluded that the 90-degree rotation technique was superior to both the 180-degree rotation and the introducer technique in adult patients in terms of insertion time, ease of insertion score, manipulation requirement, blood staining of PLMA, and post-op sore throat.

Retrospective assessment of general anesthesia-related challenges, morbidity, and death in snakes: 139 cases (2000–2022)

To summarize the anesthetic events of snakes seen at a large university hospital, identify challenges with record keeping, and assess patient and anesthesia-related morbidity and death. 139 anesthetic events were performed; only 106 cases had detailed anesthetic reports available for further analyses. Medical records of snakes that underwent general anesthesia between October 2000 and January 2022 were retrospectively reviewed. Only cases with complete anesthesia records were used to assess anesthetic parameters. Collected data included general patient details, diagnoses, procedures, premedication, induction, maintenance, monitoring, and recovery. A thorough review of the records identified issues or scenarios that resulted in poor record management as well as highlighted the most frequently used anesthetics in snakes. For premedication this was alfaxalone, butorphanol, and hydromorphone, whereas isoflurane, alfaxalone, or propofol were the most common with induction. Lastly, with maintenance, isoflurane was the most popular choice. Of the 139 cases performed, 127 animals recovered, 8 were euthanatized due to poor prognosis, and 4 failed to recover. All snakes that failed to recover had preexisting disease identified pre-, peri-, or postoperatively at necropsy. General anesthesia can be reliably and safely undertaken in snakes without severe preexisting disease. Efforts should be directed at identifying preexisting disease and maintaining and completing anesthesia records, and we recommend an auditing system to identify and correct issues as they arise.

Complication of Anesthesia in Children: A Prospective Observational Study

Background: Any anaesthetic procedure, either regional or general, has some potential for complications. For this reason, careful preoperative assessment and adequate planning of appropriate anesthetic are the cornerstones in safe pediatric anesthetic practice. But in Bangladesh, we have very limited research-based information regarding the complication of anaesthesia in children. Aim of the Study: The aim of this study was to assess the complications of anesthesia in children. Methods: This was a prospective observational study. The study was conducted in Department of Aneaesthesia, ICU &amp; Pain Medicine, Shaheed Suharawardy Medical College and Hospital, Dhaka, Bangladesh during the period from January 2018 to December 2018. In total 62 children, aged between 1 day and 15 years prepared for anesthesia associated surgery were selected as the study subjects. The incidence of intra-operative as well as post- anesthesia recovery room complications was recorded and analyzed. Data were analyzed and by using MS Excel and SPSS version 23.0 program as per necessity. Results: In this study, in analyzing the complications among the participants we observed that, bronchospam and bradycardia and hypotension were the most common intraoperative complications which were found in 11%, 10% and 8% cases respectively. On the other hand, tachycardia, prolonged unconsciousness and hypoventilation were found as the most common postoperative complications among the participants which were found in 19%, 10% and 8% cases respectively. Besides those complications some cases with restlessness, respiratory arrest, pain, shivering, hypertension, hemorrhage and laryngospasm were found in both the periods. Conclusion: Anesthesia-related morbidity and mortality can be minimized with early identification and prompt management of any complication. In this current study we observed that, preterm infants are major prone to develop respiratory complications because of using anesthesia.

Anesthesia-related Adverse Events in Obstetric Patients: A Population-based Study in Canada

(Can J Anaesth. 2022;69:72–85) Anesthesia-related morbidity, while rare, is a useful indicator for obstetric care quality and patient safety during childbirth. Previous studies—including those correlating anesthesia complications with cardiac arrest, pre-existing conditions, living in rural areas, neuraxial block, respiratory arrest, and unrecognized spinal catheterization—focused on specific neuraxial anesthesia or specific complications instead of analyzing multiple complications within a large population. The aim of this study was to determine the incidence of anesthesia complications as well as the association of anesthesia-related adverse events and medical or obstetric conditions.

Association between body mass index and difficult intubation with a double lumen tube: A retrospective cohort study

Study objectiveObesity, defined by the World Health Organization as body mass index (BMI) ≥ 30.0 kg/m2, is associated with adverse outcomes and challenges during surgery. Difficulties during endotracheal intubation, occur in 3–8% of procedures and are among the principal causes of anesthetic-related morbidity and mortality. Endotracheal intubation can be challenging in obese patients due to an array of anatomic and physiologic factors. Double lumen tubes (DLTs), the most commonly used airway technique to facilitate anatomic isolation of the lungs for one lung ventilation. However, DLTs can be difficult to properly position and are also more likely to cause airway injuries and bleeding when compared to conventional single lumen tubes. We investigated the association between BMI and difficult tracheal DLT intubation. DesignRetrospective cohort study. SettingOperating room. PatientsWe analyzed electronic records of adults having cardiac and thoracic surgery requiring general anesthesia and endotracheal intubation with DLT at the Cleveland Clinic between 2008 and 2021. MeasurementsBMI, preoperative airway abnormalities and difficult intubation, defined as more than one intubation attempt, was assessed using multivariable logistic regression. Main resultsAmong 8641 analyzed anesthetics requiring DLT, 1459 (17%) were difficult intubations. After adjusting for confounders, each 5 kg/m2 increase in BMI was associated with a marginal increase of difficult intubation, odds ratio (OR) 1.06 (95% Confidence Interval [CI]: 1.002, 1.11; P = 0.040). Difficult intubation was not associated with airway abnormalities, estimated OR 0.85 (95% CI: 0.62, 1.17; P = 0.321). There was no interaction between known airway abnormalities and BMI (P = 0.894). ConclusionsDifficult intubations with DLT remain common, but BMI is a weak predictor thereof. For example, an increase in BMI from 20 to 40 kg/m2 corresponds to an increase in average absolute risk for difficult intubation from 16 to 19%, which probably is not clinically meaningful.

Direct laryngoscopy versus video laryngoscopy for expected difficult tracheal intubation a prospective study

: Difficult tracheal intubation still contributes significantly to anaesthesia related morbidity and mortality. Poor visualisation of laryngeal structures and multiple attempts at intubation are the leading causes with the conventional laryngoscopes. Though the recently introduced video assisted devices have significantly improved the ease of intubation by their superior laryngeal visualisation, the duration of intubation may vary. Here we compared the ease of tracheal intubation using Macintosh conventional direct laryngoscope (DL) and C- MAC videolaryngoscope (VL) in patients with expected difficult tracheal intubation.A total of 140 patients undergoing elective surgery under general anaesthesia with Modified Mallampati Class 3 and 4 found during the preoperative airway assessment were included in our study with 70 patients in each group. We compared the duration of tracheal intubation, visualisation of the laryngeal inlet, additional optimising manoeuvres required, and number of attempts at intubation and incidence of oral trauma assessed at extubation between the two groups.: Analysis done using Statistical Packages for the Social Sciences (SPSS) software; Windows version 11.0 (SPSS Inc., Chicago, IL, USA).Intubation time was significantly longer in patients with VL than DL (P 0.0001) whereas visualisation of laryngeal inlet was significantly better with VL (P 0.001). Additional optimising manoeuvres (P 0.001) and incidence of oral trauma (P 0.012) were significantly less with VL whereas intubation attempts were found comparable (P 0.586).: Though VL provided significantly better laryngeal view with less need for optimising manoeuvres and less oral trauma compared to DL, the duration of intubation was significantly more with the former.

Oxygenation laryngoscope vs. nasal standard and nasal high flow oxygenation in a technical simulation of apnoeic oxygenation

BackgroundFailed airway management is the major contributor for anaesthesia-related morbidity and mortality. Cannot-intubate-cannot-ventilate scenarios are the most critical emergency in airway management, and belong to the worst imaginable scenarios in an anaesthetist’s life. In such situations, apnoeic oxygenation might be useful to avoid hypoxaemia. Anaesthesia guidelines recommend careful preoxygenation and application of high flow oxygen in difficult intubation scenarios to prevent episodes of deoxygenation. In this study, we evaluated the decrease in oxygen concentration in a model when using different strategies of oxygenation: using a special oxygenation laryngoscope, nasal oxygen, nasal high flow oxygen, and control.MethodsIn this experimental study we compared no oxygen application as a control, standard pure oxygen application of 10 l·min− 1 via nasal cannula, high flow 90% oxygen application at 20 l·min− 1 using a special nasal high flow device, and pure oxygen application via our oxygenation laryngoscope at 10 l·min− 1. We preoxygenated a simulation lung to 97% oxygen concentration and connected this to the trachea of a manikin model simulating apnoeic oxygenation. Decrease in oxygen concentration in the simulation lung was measured continuously for 20 min.ResultsOxygen concentration in the simulation lung dropped from 97 ± 1% at baseline to 40 ± 1% in the no oxygen group, to 80 ± 1% in the standard nasal oxygen group, and to 73 ± 2% in the high flow nasal oxygenation group. However, it remained at 96 ± 0% in the oxygenation laryngoscope group (p < 0.001 between all groups).ConclusionsIn this technical simulation, oxygenation via oxygenation laryngoscope was more effective than standard oxygen insufflation via nasal cannula, which was more effective than nasal high flow insufflation of 90% oxygen.

C-MAC D-Blade vs Airtraq for Intubation with Manual Inline Axial Stabilisation- A Randomised Clinical Trial

Introduction: One of the most important skills in anaesthesia is securing the airway with an endotracheal tube. Difficult tracheal intubation however is considered one of the major contributors of anaesthesia related morbidity and mortality. Video laryngoscopy offers several advantages during endotracheal intubation. The view of the glottis provided by Videolaryngoscopes is better compared to the Macintosh laryngoscope in difficult airways which makes it more attractive for routine difficult airway intubations. Aim: To compare the time taken for intubation between two Videolaryngoscopes, namely C-MAC D-blade and Airtraq and to assess the quality of laryngoscopy view between the two groups. Materials and Methods: This was a randomised clinical trial conducted in 116 American Society of Anesthesiologists 1 (ASA1) and ASA2 patients undergoing elective surgeries in Pondicherry Institute of Medical Sciences. Patients are randomised into two groups, Group C-MAC D-blade and Group Airtraq by computer randomisation. Statistical analysis was performed using t-test, Repeated measures of ANOVA was used to find the significance from preinduction to 10 mins period for each group and Bonferoni’s correction for intergroup comparison. Results: The time taken for intubation was comparable in two study groups (Group C-MAC D-blade 41.88 secs) and (Group Airtraq -40.78 sec) with p-value of 0.734. Laryngoscopic view was not statistically significant with p-value of 0.083. Optimisation maneuvers were required in 63.8% in Group Airtraq on comparison with 44.8% in Group C-MAC D-blade. In both Group C-MAC D-blade and Group Airtraq, there was a significant rise in the heart rate and BP at 0 minute compared to preinduction. But after 5 minutes, the heart rate and BP were back to preinduction values. Conclusion: Both the Videolaryngoscopes, C-MAC D-blade and Airtraq performed equally, with respect to time taken for intubation and laryngoscopic view. However, External Laryngeal Manipulation (ELM) was required more in Group Airtraq and was statistically significant.

Evaluation of different airway tests to determine difficult intubation in apparently normal adult patients undergoing surgical procedures

BackgroundInadequate maintenance of a patient’s airway represents a major cause of anesthesia-related morbidity and mortality. This study was designed to evaluate common preoperative clinical tests to determine the risk of difficult endotracheal intubation in apparent “normal” adult patients undergoing surgical procedures.MethodsA prospective observational cohort study was performed on 160 consecutive adult patients undergoing surgical procedures at an academic medical center in Jordan from 20 May 2019 until 11 February 2020.Preoperative assessment of airway risk stratification was performed by the following clinical tests: the mandible protrusion test (MPT), thyromental (TMD) and sternomental (SMD) distances, inter-incisor gap (IIG), and the modified Mallampati tests with tongue protrusion (MMT-TP) and without tongue protrusion (MMT-NTP). Grade C on the MPT, TMD ≤ 6 cm, SMD ≤ 12 cm, and MMT grades III and IV were considered to be predictors of difficult endotracheal intubations. A modified Cormack-Lehane grading (MCLG) of laryngoscopic views with backward, upward, and right-sided pressure on the thyroid and cricoid cartilages (BURP) maneuver was also documented, with grades 2B, 3, and 4 considered to be difficult airways for intubation.ResultsFifteen patients (9.4%) were classified as MCLG 2B, 3, and 4, with age significantly associated with the MCLG grade (P = 0.028). The sensitivity and Youden’s index of MMT-TP were found to be the lowest (40% and 0.29, respectively). The MPT was the most accurate and specific test (90.63 and 95.17%, respectively), with the highest PPV (50%), Youden’s index (0.42), and area under the curve (AUC) (0.781). Bivariant analysis of MPT and the t-test of the mean TMDs and SMDs revealed significant associations between these airway tests and the difficulty of intubation (P values: < 0.001, 0.02, < 0.01, respectively).ConclusionThe MPT, with its highest accuracy, specificity, positive predictive value, and good sensitivity may be used as a routine screening test for preoperative prediction of difficult endotracheal intubations.

A multicentre study of the trend of adverse events during outpatient anaesthesia in Switzerland during 2000-2016.

Over the last three decades, the use of outpatient surgery has been steadily increasing. Simultaneously, there has been an inciting movement to measure and improve healthcare quality and safety. Nevertheless, anaesthesia-related morbidity remains significant. We aimed to evaluate the incidence of intraoperative adverse events (IAEs) occurring during outpatient surgery. We used data from the Anaesthesia Databank Switzerland (ADS), a voluntary register. We assessed the overall and specific incidence of IAEs, according to a predefined list of technical, cardiovascular, organisational, respiratory, and general incidents in Switzerland between 2000 and 2016. Primary and secondary outcomes were modelled using multi-level logistic regression analysis, and the time trend on the probabilities of events was assessed. Between 2000 and 2016, 289,948 outpatient anaesthesia procedures were performed. During this period, the estimated probability of overall intraoperative adverse events decreased from 10.8% to 6.3%, and from 2.3% to 1.4% for technical incidents, from 3.0% to 2.2% for cardiovascular, from 1.6% to 1.3% for organisational, from 0.9% to 0.7% for general, and from 1.1% to 0.7% for respiratory incidents. The occurrence of intraoperative adverse events in ambulatory anaesthesia has continuously decreased between 2000 and 2016. This trend is essentially attributable to a reduction in the incidence of technical, cardiovascular and organisational events. &nbsp.

Pediatric airway: What is new in approaches and treatments?

Perioperative morbidity and mortality are high among patients in the extremes of life undergoing anesthesia. Complications in children occur mainly as a result of airway management-related events such as difficult approach, laryngospasm, bronchospasm and severe hypoxemia, which may result in cardiac arrest, neurological deficit or death. Reports and new considerations that have changed clinical practice in pediatric airway management have emerged in recent years. This narrative literature review seeks to summarize and detail the findings on the primary cause of morbidity and mortality in pediatric anesthesia and to highlight those things that anesthetists need to be aware of, according to the scientific reports that have been changing practice in pediatric anesthesia. This review focuses on the identification of “new” and specific practices that have emerged over the past 10 years and have helped reduce complications associated with pediatric airway management. At least 9 practices grouped into 4 groups are described: assessment, approach techniques, devices, and algorithms. The same devices used in adults are essentially all available for the management of the pediatric airway, and anesthesia-related morbidity and mortality can be reduced through improved quality of care in pediatrics.
