RESUMO

PURPOSE: Awake extubation and deep extubation are commonly used anesthesia techniques. In this study, the safety of propofol-assisted deep extubation in the dental treatment of children was assessed. MATERIALS AND METHODS: Children with severe caries who received dental treatment under general anesthesia and deep extubation between January 2017 and June 2023 were included in this study. Data were collected on the following variables: details and time of anesthesia, perioperative vital signs, and incidence of postoperative complications. The incidence of laryngeal spasm (LS) was considered to be the primary observation indicator. RESULTS: The perioperative data obtained from 195 children undergoing dental treatment was reviewed. The median age was 4.2 years (range: 2.3 to 9.6 years), and the average duration of anesthesia was 2.56 h (range 1 to 4.5 h). During intubation with a videoscope, purulent mucus was found in the pharyngeal cavity of seven children (3.6%); LS occurred in five of them (2.6%), and one child developed a fever (T = 37.8 °C) after discharge. Five children (2.6%) experienced emergence agitation (EA) in the recovery room. Also, 13 children (6.7%) experienced epistaxis; 10 had a mild experience and three had a moderate experience. No cases of airway obstruction (AO) and hypoxemia were recorded. The time to open eyes (TOE) was 16.3 ± 7.2 min. The incidence rate of complications was 23/195 (11.8%). Emergency tracheal reintubation was not required. Patients with mild upper respiratory tract infections showed a significantly higher incidence of complications (P < 0.001). CONCLUSIONS: Propofol-assisted deep extubation is a suitable technique that can be used for pediatric patients who exhibited non-cooperation in the outpatient setting. Epistaxis represents the most frequently encountered complication. Preoperative upper respiratory tract infection significantly increases the risk of complications. The occurrence of EA was notably lower than reported in other studies.

RESUMO

INTRODUCTION: Laryngospasm is an involuntary, sustained closure of sphincter musculature that leads to an unpleasant subjective experience of dyspnea and choking. It is an underreported symptom in amyotrophic lateral sclerosis (ALS). In this study we aimed to better characterize the prevalence and clinical characteristics of laryngospasm in ALS patients. METHODS: The medical records of 571 patients with ALS followed between 2008 and 2018 were searched for evidence of laryngospasm. A total of 23 patients with laryngospasm were identified and the data related to patient and laryngospasm characteristics were extracted. RESULTS: Laryngospasm was reported in 4% of ALS patients. Females comprised 57% of patients and their mean age was 63.4 years. Laryngospasm frequently manifested in patients with moderate bulbar dysfunction and seemed independent of respiratory function. Among laryngospasm patients, 26% were cigarette smokers and 13% had a history of gastroesophageal reflux. The most common reported trigger was excessive saliva irritating the vocal cords (35%) followed by eating a meal (17%). There was significant variation in laryngospasm frequency (up to 5 per hour) and duration (seconds to minutes). Most patients could not identify an effective coping mechanism, although 13% reported that drinking water was effective. DISCUSSION: Despite its low prevalence in ALS, laryngospasm should be included in the symptom inquiry. The present findings may improve patient care through increased recognition of the clinical features of laryngospasm in ALS patients, identifying a link between laryngospasm and moderate bulbar dysfunction, and highlighting trigger avoidance as a management strategy. Additional research is required to understand the pathophysiology and optimal treatment.

RESUMO

BACKGROUND: The timing of laryngeal mask airway (LMA) removal remains undefined. This study aimed to assess the optimal timing for LMA removal and whether topical anesthesia with lidocaine could reduce airway adverse events. METHODS: This randomized controlled trial assessed one-to-six-year-old children with ASA I-II scheduled for squint correction surgery under general anesthesia. The children were randomized into the LA (lidocaine cream smeared to the cuff of the LMA before insertion, with mask removal in the awake state), LD (lidocaine application and LMA removal under deep anesthesia), NLA (hydrosoluble lubricant application and LMA removal in the awake state) and NLD (hydrosoluble lubricant application and LMA removal in deep anesthesia) groups. The primary endpoint was a composite of irritating cough, laryngeal spasm, SpO2 < 96%, and glossocoma in the recovery period in the PACU. The secondary endpoints included the incidence of pharyngalgia and hoarseness within 24 h after the operation, duration of PACU stay, and incidence of agitation in the recovery period. The assessor was unblinded. RESULTS: Each group included 98 children. The overall incidence of adverse airway events was significantly lower in the LA group (9.4%) compared with the LD (23.7%), NLA (32.6%), and NLD (28.7%) groups (P=0.001). Cough and laryngeal spasm rates were significantly higher in the NLA group (20.0 and 9.5%, respectively) than the LA (5.2 and 0%, respectively), LD (4.1 and 1.0%, respectively), and NLD (9.6 and 2.1%, respectively) groups (P=0.001). Glossocoma incidence was significantly lower in the LA and NLA groups (0%) than in the LD (19.6%) and NLD (20.2%) groups (P< 0.001). At 24 h post-operation, pharyngalgia incidence was significantly higher in the NLA group (15.8%) than the LA (3.1%), LD (1.0%), and NLD (3.2%) groups (P< 0.001). CONCLUSIONS: LMA removal in the awake state after topical lidocaine anesthesia reduces the incidence of postoperative airway events. TRIAL REGISTRATION: ChiCTR, ChiCTR-IPR-17012347 .

RESUMO

OBJECTIVES: To determine the incidence of potentially life-threatening complications of hypocalcemia in infants and children in Olmsted County, Minnesota; and to determine if vitamin D deficiency contributed to these events and was, at the time of clinical presentation, considered as a possible cause. STUDY DESIGN: In this population-based descriptive study, data were abstracted from the Rochester Epidemiology Project, a medical record linkage system covering 95% of patients in Olmsted County, Minnesota. Participants were children aged 0-5 years who resided in Olmsted County between January 1, 1996 and June 30, 2017, and who received diagnoses of seizures, cardiomyopathy, cardiac arrest, respiratory arrest, laryngospasm, and/or tetany. The incidence of hypocalcemia plus a potentially life-threatening complication was calculated. RESULTS: Among 15 419 patients aged 0-5 years in Olmsted County during the study period, 1305 had eligible complications: 460 had serum calcium checked within 14 days of presentation and 85 had hypocalcemia. Patients were excluded when causes other than hypocalcemia likely triggered the complication, leaving 16 children whose complication was attributed to hypocalcemia. Three of these 16 patients had a serum 25-hydroxyvitamin D measurement and 2 were deficient (≤6 ng/mL [15 nmol/L]). Among children aged 0-5 years, the incidence of hypocalcemia plus a potentially life-threatening complication was 6.1 per 100 000 person-years (95% CI, 3.5-10.0). CONCLUSIONS: Vitamin D deficiency is an underinvestigated cause of complications of hypocalcemia in children. Serum calcium and 25-hydroxyvitamin D should be measured in children with these complications to identify possibly life-threatening vitamin D deficiency.

RESUMO

BACKGROUND: Laryngeal mask UNIQUE® (LMAU) is supraglottic airway device with good clinical performance and low failure rate. Little is known about the ideal position of the LMAU on the magnetic resonance imaging (MRI) and whether radiological malposition can be associated with clinical performance (audible leak) in children. The primary aim of the study was to evaluate incidence of the radiologic malposition of the LMAU according to size. The secondary outcome was the clinical performance and associated complications (1st attempt success rate, audible leak) in LMAUs in correct position vs. radiologically misplaced LMAUs. METHODS: In prospective observational study, all paediatric patients undergoing MRI of the brain under general anaesthesia with the LMAU were included (1.9.2016-16.5.2017). The radiologically correct position: LMAU in hypopharynx, proximal cuff opposite to the C1 or C2 and distance A (proximal cuff end and aditus laryngis) ≤ distance B (distal cuff end and aditus laryngis). Malposition A: LMAU outside the hypopharynx. Malposition B: proximal cuff outside C1-C2. Malposition C: distance A ≥ distance B. We measured distances on the MRI image. Malposition incidence between LMAU sizes and first attempt success rate in trainees and consultant groups was compared using Fisher exact test, difference in incidence of malpositions using McNemar test and difference in leakage according to radiological position using two-sample binomial test. RESULTS: Overall 202 paediatric patients were included. The incidence of radiologically defined malposition was 26.2% (n = 53). Laryngeal mask was successfully inserted on the 1st attempt in 91.1% (n = 184) cases. Audible leak was detected in 3.5% (n = 7) patients. The radiologically defined malposition was present in 42.9% (n = 3) cases with audible leak. The rate of associated complications was 1.5% (n = 3): laryngospasm, desaturation, cough. In 4.0% (n = 8) the LMAU was soiled from blood. Higher incidence of radiological malposition was in LMAU 1.0, 1.5 and LMAU 3, 4 compared to LMAU 2 or LMAU 2.5 (p < 0.001). CONCLUSION: Malposition was not associated with impaired clinical performance (audible leak, complications) of the LMAU or the need for alternative airway management.

RESUMO

BACKGROUND: Recent upper respiratory tract infection (URI) is associated with increased incidence of perioperative complications in children undergoing open heart surgery. As a result, surgery is often postponed. However, the effect of recent URI on the incidence of perioperative complications in children undergoing therapeutic cardiac catheterisation is unknown. We investigated the perioperative outcomes of congenital heart disease (CHD) children with recent URI who underwent elective therapeutic catheterisation. METHODS: We prospectively included children treated for CHD. Before surgery, parents or legal guardians were interviewed to complete a questionnaire on the child's demographics, history of asthma and passive smoking, and URI symptoms. Recorded perioperative respiratory adverse events (PRAEs) included laryngospasm, bronchospasm, breath holding, oxygen desaturation, and severe cough. Information on postoperative dysphoria, fever, copious sputum, and vomiting was obtained by telephone 24 h after surgery. RESULTS: Of 363 included children, 169 had recently (within 2 weeks) had a URI. The URI did not affect the incidence of laryngospasm, bronchospasm, breath holding, fever, or vomiting. The incidence of desaturation, severe cough, dysphoria, and copious sputum were significantly increased. Independent risk factors for PRAEs in children with a recent URI included age, passive smoking, and presence of rhinorrhoea or moist cough. The lengths of stay in the hospital and intensive care unit were not significantly different between groups. CONCLUSION: Although recent URI increased the incidence of PRAEs in children undergoing therapeutic cardiac catheterisation, most CHD patients with recent URI can undergo elective therapeutic cardiac catheterisation without serious adverse events or prolonged hospitalisation.

RESUMO

BACKGROUND: Significant cardiorespiratory events are frequent in patients undergoing gastrointestinal endoscopy. Central to the occurrence of respiratory events is an unsecured airway. This study sought to determine the efficacy of a new laryngeal mask airway, the LMA®GastroTM Airway (Teleflex Medical, Athlone, Ireland), in patients undergoing upper gastrointestinal endoscopy. New design features include a dedicated channel for oesophageal intubation and separate channel with terminal cuff for lung ventilation. METHODS: In a prospective, open label, observational study, 292 ASA physical status classification 1 and 2 patients at low risk of pulmonary aspiration undergoing upper gastrointestinal endoscopy received i.v. propofol anaesthesia and standardized insertion of the LMA®GastroTM Airway. Endoscopy outcomes included insertion success, first attempt success, and ease of endoscope insertion. LMA®GastroTM Airway outcomes included insertion success, first attempt success, ease of insertion, lowest oxygen saturation, airway compromise, laryngospasm, bloodstained device, and sore throat. RESULTS: Per protocol analysis (n=290), the endoscopy success rate amongst the cohort with successful LMA®GastroTM Airway insertion was 99% [95% confidence interval (CI): 98, 100]. LMA®GastroTM Airway insertion success rate (n=292) was 99% (95% CI: 98, 100). For endoscopy and LMA®GastroTM Airway insertion success, the lower limit of the 95% CIs was at least 98%, indicating LMA®GastroTM Airway efficacy. Median (inter-quartile range) lowest intraoperative oxygen saturation was 98% (98, 99). Only one serious adverse event occurred (re-admission for sore throat and inability to tolerate fluids) and was reported to the Tasmanian Health and Medical Human Research Ethics Committee. CONCLUSIONS: The LMA®GastroTM Airway appears effective for clinical use in upper gastrointestinal endoscopy. CLINICAL TRIAL REGISTRATION: ACTRN12616001464459.

RESUMO

The number of children with caries requiring general anesthesia to achieve comprehensive dental care and the demand for dentist anesthesiologists to provide ambulatory anesthesia for these patients is increasing. No current published studies examine the safety and outcomes of ambulatory anesthesia performed by dentist anesthesiologists for dental procedures in pediatric patients, and there is no national requirement for reporting outcomes of these procedures. In 2010, the Society for Ambulatory Anesthesia Clinical Outcomes Registry was developed. This Web-based database allows providers of ambulatory anesthesia to track patient demographics and various outcomes of procedures. Our study is a secondary analysis of data collected in the registry over a 4-year period, 2010-2014. Of the 7041 cases reviewed, no cases resulted in serious complications, including death, anaphylaxis, aspiration, cardiovascular adverse events, or neurologic adverse events. Of the 7041 cases reviewed, 196 (3.0%) resulted in a predischarge or postdischarge adverse event. The predischarge adverse event occurring with the highest frequency was laryngospasm, occurring in 35 cases (0.50%). The postdischarge adverse event occurring with the highest frequency was nausea, reported by 99 patients (5.0%). This study provides strong clinical outcomes data to support the safety of office-based anesthesia as performed by dentist anesthesiologists in the treatment of pediatric dental patients.

RESUMO

Adverse reactions (ARs) to intravenous (IV) radiographic contrast range from mild urticaria to life-threatening anaphylaxis. Intraluminal contrast dye is routinely used in the urinary tract with a minimal perceived risk of AR. We used the Healthcare Cost and Utilization Project State Inpatient Databases for California and Florida from 2007 to 2011 to identify patients who received urinary tract contrast dye for retrograde pyelography, percutaneous pyelography, retrograde/other cystogram, and ileal conduitogram. After excluding patients who had received IV contrast for other radiologic studies, ARs to contrast were identified by a composite end point of diagnoses not present on admission including shock, anaphylaxis, iatrogenic hypotension, urticaria, angioedema, laryngospasm, laryngeal edema, and/or a new diagnosis of contrast reaction. Overall, 76 174 patients were included who had undergone non-IV urinary tract imaging, 367 (0.48%) of whom developed an AR. On multivariate analysis, receipt of contrast in the lower urinary tract (odds ratio [OR]: 1.8; p=0.04) or upper urinary tract by retrograde pyelography (OR: 1.6; p=0.04) or antegrade pyelography (OR: 2.0; p=0.007) increased the risk of AR compared with control patients. The use of contrast dye in the urinary tract is associated with a low, but present risk of AR. PATIENT SUMMARY: We looked at patients who underwent a urologic procedure using radiographic contrast media in the urinary tract. Although adverse reactions (ARs) may occur with the use of contrast media in the urinary tract, these reactions are experienced by a minority of patients (approximately 1 in 200). In addition, we found that an allergy to intravenous contrast does not increase a patient's risk of an AR to contrast within the urinary tract.

RESUMO

PURPOSE OF REVIEW: This review summarizes the current evidence for the management of children with recent upper respiratory tract infections (URTIs). Furthermore, the review includes management guidelines for children with URTIs. RECENT FINDINGS: Good history and clinical examination is sufficient in most children presenting with URTI. Testing for immune markers or preoperative nitric oxide measurement does not add any additional value. Preoperative bronchodilator administration, intravenous induction with propofol, and noninvasive airway management all reduce the occurrence of respiratory adverse events. SUMMARY: Most children can be safely anaesthetized even in the presence of an URTIs if the perioperative anaesthesia management is optimized. In this review article, we have included a management algorithm for children with URTI presenting for elective surgery.

RESUMO

We aimed to compare cuffed and uncuffed endotracheal tubes (ETTs) with ProSealTM laryngeal mask airway (PLMA) in terms of airway security and extubation, starting out from the hypothesis that PLMA will provide alternative airway safety to the endotracheal tubes, and that airway complications will be less observed. After obtaining approval from the local Ethics Committee and parental informed consent, 120 pediatric patients 1-24 months old, American Society of Anesthesiologists physical status I-II, requiring general anesthesia for elective lower abdominal surgery, were randomized into PLMA (Group P, n = 40), cuffed ETT (Group C, n = 40), and uncuffed ETT (Group UC, n = 40) groups. The number of intubation or PLMA insertion attempts was recorded. Each patient's epigastrium was auscultated for gastric insufflation, leak volumes and air leak fractions (leak volume/inspiratory volume) were recorded. Post-operative adverse events related to airway management were also followed up during the first post-operative hour. Demographic and surgical data were similar among the groups. There were significantly fewer airway manipulations in the Group P than in the other groups (p < 0.01), and leak volume and air leak fractions were greater in the Group UC than in the other two groups (p < 0.01). Laryngospasm was significantly lower in the Group P during extubation and within the first minute of post-extubation than in the other groups (p < 0.01). Based on this study, PLMA may be a good alternative to cuffed and uncuffed ETTs for airway management of infants due to the ease of manipulation and lower incidence of laryngospasm.

RESUMO

BACKGROUND: Patients with mucopolysaccharidoses (MPS) are generally considered high risk for anesthesia care, owing to disease-related factors. Sanfilippo syndrome type A (MPS IIIA) is the most frequently occurring MPS. Anesthesia-specific information for MPS IIIA is not readily available in the literature. OBJECTIVES: To report post hoc analyses on anesthesia care and outcomes from a 2-year study of the natural history of patients with untreated MPS IIIA (NCT01047306). METHODS: Subjects were ≥1 year of age, developmental age ≥1 year, and without significant central nervous system impairment (other than that due to MPS IIIA) or issues that would preclude study procedures. Procedures requiring general anesthesia included brain/abdominal magnetic resonance imaging, lumbar puncture, and echocardiography. Sedation, intubation, and extubation procedures as well as postoperative airway problems were recorded at baseline and 6, 12, and 24 months of age. RESULTS: Twenty-five patients (baseline age, 13-220 months) received a total of 94 general anesthetics. Patients successfully received oral sedation prior to 76 of 94 anesthetics. No patients required airway intervention or oxygen supplementation during sedation. All anesthesia providers described facemask ventilation and endotracheal intubations as 'easy'. All subjects were successfully extubated after completion of the procedures. No patients required reintubation. Six (24%) patients had episodes of postoperative airway problems: wheezing (7/94, 7.4%), croup (6/94, 6.4%), and laryngospasm (2/94, 2.1%). CONCLUSION: We found no change in the modified Cormack-Lehane intubation grades in 25 Sanfilippo syndrome type A children over the 2-year study period.

RESUMO

CONTEXT: Non-invasive ventilation (NIV) is increasingly used in pediatric intensive care units to limit the complications associated with intubation. However, NIV may fail, and the delay in initiating invasive ventilation may be associated with adverse outcomes. The objective of this retrospective study was to evaluate the safety of tracheal intubation after NIV failure. METHODS: Consecutive tracheal intubation procedures were prospectively evaluated in our PICU from 01/2011 to 02/2012, as part of the National Emergency Airway Registry for Children (NEAR4KIDS) collaborative. The incidence of severe tracheal intubation associated events (TIAEs, including cardiac arrest, esophageal intubation with delayed recognition, emesis with aspiration, hypotension requiring intervention, laryngospasm, malignant hyperthermia, pneumothorax, and pneumomediastinum) and severe desaturation (below 80% when pre-intubation saturation was greater than 94%) were recorded prospectively. NIV use before intubation was retrospectively assessed. RESULTS: 100 consecutive intubation events were analyzed, 46 of which followed NIV failure. NIV exposed and non-exposed groups had different baseline characteristics, with lower weight, more frequent lower airway and lung disorder, and lower PIM2 score at admission in NIV failure patients (all P < 0.05). The nasal route for intubation was more frequent in NIV patients (P < 0.01). The incidence of severe TIAE or desaturation was 41% in the NIV failure group and 24% in primarily intubated patients (P = 0.09). CONCLUSION: Complications occurred in 41% of intubations after NIV failure in this series. Further research is warranted to evaluate strategies to prevent these complications and to identify conditions in which intubation should not be delayed for a trial of NIV.

RESUMO

PURPOSE: To study the possibility of desflurane use for induction of anesthesia. MATERIALS AND METHODS: We analysed the intra- and immediate postoperative periods in 125 patients. Depending on the intended anesthesia method patients were randomised (the method of the envelopes) and included in one of two study groups: 1--volatile desflurane-based anesthesia (n = 62); 2--volatile sevoflurane-based anesthesia (n = 63). RESULTS: Desflurane based anesthesia led to apnea until the installation of laryngeal mask in 94.5% of patients (of 54), for whom a completion of inhalation induction was possible, whereas sevoflurane based anesthesia.led to apnea occurred only in one patient (1.6%). CONCLUSIONS: "Step up" desflurane-based inhalational induction and sevoflurane-based maximum concentration inhalational induction "without primaryfilling of the circuit" showed no significant in time necessary for achieving an anesthetic concentration essential for LMA installation. In both groups it was 3-5 min. desflurane-based volatile induction with addition of fentanyl led to apnea in 97% of patients and associates with a higher risk of bronchospasm.

RESUMO

INTRODUCTION: Perioperative adverse events are more common in children compared to adult population. Reporting an adverse event proves effective in identifying problems and helps in prevention and early management. Our objective was to identify the types, incidence, and the time of occurrence of perioperative adverse event. We also aimed to find out whether the occurrence of the types of adverse events differ in children below and above five years. METHODS: This was a prospective study in 242, ASA Physical Status I and II children aged day one to 14 years, receiving general anesthesia with laryngeal mask airway for various elective surgeries. Adverse events observed in the perioperative period were recorded. RESULTS: Adverse events related to respiratory system (n=26, 55%) were the most common followed by cardiovascular system (n= 14, 30%). Adverse events were observed in 24(10%) children in the operating room and in 20 (8%) children in the post anaesthesia care unit. In the operating room, majority (14 of 27, 52%) of the events occurred immediately after removal of laryngeal mask airway. Respiratory events were more common in children below five years (p=0.007), whereas cardiac events were more common in children above five years (p=0.02). CONCLUSIONS: The commonest adverse event in children is related to respiratory system. Adverse events occur more frequently in the operating room, mostly immediately after removal of laryngeal mask airway. Respiratory events are more frequent in children below five years whereas cardiac events are more frequent in children above five years.

RESUMO

BACKGROUND: Exercise-induced respiratory symptoms are common among adolescents. Exercise is a known stimulus for transient narrowing of the airways, such as exercise-induced bronchoconstriction (EIB) and exercise-induced laryngeal obstruction (EILO). Our aim was to investigate the prevalence of EIB and EILO in a general population of adolescents. METHODS: In this cross-sectional study, a questionnaire on exercise-induced dyspnoea was sent to all adolescents born in 1997 and 1998 in Uppsala, Sweden (n=3838). A random subsample of 146 adolescents (99 with self-reported exercise-induced dyspnoea and 47 without this condition) underwent standardised treadmill exercise tests for EIB and EILO. The exercise test for EIB was performed while breathing dry air; a positive test was defined as a decrease of ≥10% in FEV1 from baseline. EILO was investigated using continuous laryngoscopy during exercise. RESULTS: The estimated prevalence of EIB and EILO in the total population was 19.2% and 5.7%, respectively. No gender differences were found. In adolescents with exercise-induced dyspnoea, 39.8% had EIB, 6% had EILO and 4.8% had both conditions. In this group, significantly more boys than girls had neither EIB nor EILO (64.7% vs 38.8%; p=0.026). There were no significant differences in body mass index, lung function, diagnosed asthma or medication between the participants with exercise-induced dyspnoea who had or did not have a positive EIB or EILO test result. CONCLUSIONS: Both EIB and EILO are common causes of exercise-induced dyspnoea in adolescents. EILO is equally common among girls and boys and can coexist with EIB.

RESUMO

BACKGROUND: Desflurane's short emergence time supports fast track anaesthesia. Data on the rate of upper airway complications and emergence time when desflurane is used with laryngeal mask airway (LMA) are controversial and limited. OBJECTIVES: To compare recovery time variables and the rates of upper airway adverse events in patients with an LMA undergoing general surgery with desflurane, sevoflurane, isoflurane or propofol anaesthesia. DESIGN: A systematic review and meta-analysis of randomised controlled trials (RCTs). DATA SOURCES: A systematic search for eligible RCTs in Embase (Elsevier) and in PubMed (National Library of Medicine) databases up to September 2013. ELIGIBILITY CRITERIA: RCTs investigating the rates of cough overall, cough at emergence, laryngospasm, time to eye opening, time to removal of the LMA, time to respond to command and time to state date of birth in patients with an LMA, during emergence from desflurane, sevoflurane, isoflurane or propofol anaesthesia. RESULTS: Thirteen RCTs were included and analysed. We found a strong interstudy variability. There was no difference in the rates of upper airway events between desflurane and sevoflurane or between desflurane and a control group consisting of all the other anaesthetics combined. Comparing desflurane (n = 284) with all other anaesthetic groups (n = 313), the risk ratio [95% confidence interval (95% CI)] was 1.12 (0.63 to 2.02, P = 0.70). Cough at emergence was only measured in patients receiving desflurane (n = 148) and sevoflurane (n = 146): the risk ratio (95% CI) was 1.49 (0.55 to 4.02, P = 0.43). Laryngospasm was rare and there was no significant difference in its incidence when desflurane (n = 262) was compared with all other anaesthetics combined (n = 289; risk ratio 1.03; 95% CI 0.33 to 3.20, P = 0.96). The times of all emergence variables were significantly faster in the desflurane group than in all other groups. CONCLUSION: When using an LMA, upper airway adverse reactions in association with desflurane anaesthesia were no different from those noted with sevoflurane, isoflurane or propofol anaesthesia. Emergence from general anaesthesia with desflurane is significantly faster than all the other anaesthetics. Due to interstudy variations and the small size of the trials, further large-scale, multicentre studies are required to confirm or refute the results of this meta-analysis.

RESUMO

BACKGROUND: Either controlled ventilation or spontaneous respiration is commonly used in general anesthesia for inhaled foreign body removal via rigid bronchoscopy. Controversy in the literature exists concerning which form of ventilation is optimally suited for bronchoscopy. We performed a meta-analysis to compare controlled ventilation and spontaneous respiration with respect to complications, operation time, and anesthesia recovery time. METHODS: We searched MEDLINE (1946-2013) and the Cochrane Central Register of Controlled Trials, EMBASE. The articles were evaluated for validity, and the data on complications, including desaturation, laryngospasm, laryngeal edema, bucking and coughing, body movement, breath holding, operation time, and anesthesia recovery time, were extracted by the authors and summarized using odds ratios, mean differences, and 95% confidence intervals (CIs). RESULTS: From the included studies, 423 subjects received controlled ventilation, whereas 441 subjects received spontaneous respiration. There was no significant difference in the incidence of desaturation between controlled ventilation and spontaneous respiration (odds ratio, 0.70; 95% CI, 0.30-1.63). However, the incidence of laryngospasm was lower when controlled ventilation was performed (OR, 0.27; 95% CI, 0.10-0.76). The operation time (mean difference, -9.07 min; 95% CI, -14.03 to -4.12) was shorter in the controlled ventilation group. CONCLUSIONS: Current evidence does not show a preference for either controlled ventilation or spontaneous respiration, although laryngospasm has a lower incidence when controlled ventilation is performed. Additional clinical studies are required to substantiate this issue.

RESUMO

OBJECTIVES: This study aimed to evaluate the demographics of spasmodic dysphonia in the Indian population and to analyse the optimum dose titration of botulinum toxin type A in this group. A comparative analysis with international studies was also performed. METHOD: The study involved a retrospective analysis and audit of botulinum toxin type A dose titration in spasmodic dysphonia patients who visited our voice clinic between January 2005 and January 2012. RESULTS: The average total therapeutic dose required for patients with adductor spasmodic dysphonia was 4.2 U per patient per vocal fold (total 8.4 U per patient), and for patients with abductor spasmodic dysphonia, it was 4.6 U per patient. CONCLUSION: Our audit revealed that 80 per cent of the spasmodic dysphonia patients were male, which contrasts dramatically with international studies, wherein around 80 per cent of spasmodic dysphonia patients were female. Our study also revealed a higher dose titration of botulinum toxin for the Indian spasmodic dysphonia population in both adductor and abductor spasmodic dysphonia cases.
