Comparison of Macintosh laryngoscope and King Vision video laryngoscope for endotracheal intubation in adult patients

Background: Development of video laryngoscope has made management of airway easier. 0ur study was aimed to compare the efficacy of Macintosh laryngoscope and King Vision video laryngoscope for endotracheal intubation in adult patients under general anesthesia. Objectives: The primary objective of the study was to compare the glottic view obtained , the need for external manipulation, endotracheal tube insertion time and attempts taken for successful intubation with Macintosh laryngoscope and King Vision video laryngoscope. The secondary objective was to estimate the changes in hemodynamic parameters and to evaluate the occurrence of complications during intubation. Materials and Methods: The study included 136 patients posted for surgery under general anesthesia. Patients were randomly allocated in group C (N=68) and group V (N=68 ).Endotracheal intubation was done in group C by Macintosh and in group V by King Vision video laryngoscope. Laryngoscopy was assessed by Cormack Lehane grading and the need for any manipulation. The intubation time was calculated with each blade. Hemodynamic parameters were recorded and any complication during laryngoscopy and intubation were noted. The observations were analysed statistically by SPSS Program for windows version 28. Results: In group C, 61.8% of patients had Cormack and Lehane score I while in group V 76.5 % of patients had score I . Mean time of successful intubation was 34.90±8.35 sec in group C while in group V it was 32.82± 5.20 second . There was no statistical difference in distribution of patients according to number of attempts of intubation. In group C, 64.7% of patients needed external laryngeal pressure while in group V 97.1 % patients were intubated without external laryngeal pressure. Both the groups were comparable in relation to changes in hemodynamic parameters and any complications associated with laryngoscopy and intubation. Conclusion: We conclude that glottic view is better obtained with King Vision Video laryngoscope whereas optimisation of position and external laryngeal manipulation is often required with Macintosh laryngoscope to get similar glottic view. Introduction of King Vision video laryngoscope into the oral cavity takes time but intubation is easier with it. Hemodynamic variables and complications during the procedure are equally distributed between the two devices.

The efficacy of acupuncture-assisted blind insertion of bullet nasointestinal tube method in patients with ischemic stroke: A retrospective study

Objective: To explore the efficacy of Traditional Chinese Medicine (TCM) acupuncture-assisted blind insertion of bullet nasointestinal tube method in patients with ischemic stroke. Methods: This is a retrospective study using clinical records of 180 patients with ischemic stroke, hospitalized in the Department of Neurology of the Zhejiang Province Tertiary Class A Hospital, Huzhou, China from July 2022 to June 2023. The patients were divided into two groups on the basis of the nasogastric tube insertion method. We selected 90 patients for each group from the database of records by using a random list method. Patients in the observation group underwent TCM acupuncture-assisted blind insertion of nasointestinal tube and those in the control group underwent the traditional bedside blind insertion of bullet nasointestinal tube. Success rate of tube insertion, average tube insertion time, intragastric insertion time, stomach time to jejunal insertion, patient comfort, and patient satisfaction in both groups were compared. Results: The success rate of nasointestinal tube insertion was significantly higher in the observation group compared to the control group (96.6% and 88.9%, p<0.05). There was no statistically significant difference in the time of nasoenteral tube insertion into the stomach (p>0.05). The insertion time from stomach to jejunum in the observation group was significantly shorter than in the control group (p<0.05). The patient comfort and satisfaction levels were significantly higher in the observation group compared to the control group (p<0.05). Conclusion: TCM acupuncture-assisted blind insertion of bullet nasointestinal tube method improves the success rate of tube insertion, shortens the average catheterization time from the stomach to the jejunum and improves patient’s comfort and satisfaction. doi: https://doi.org/10.12669/pjms.40.10.9936 How to cite this: Zhao H, Chen J, Chen H, Lv X, Lu Z, Sun Y.

Effectiveness of an Endotracheal Tube Adjustable Stabilizing Set to Prevent Unplanned Extubation in Preterm Infants: A Quasi-experimental Study

Preterm infants born before 34 weeks of gestation often face respiratory challenges and may require resuscitation with an endotracheal tube and ventilator support. Unplanned extubation is a common problem for such infants, affecting their care and outcomes. This quasi-experimental study compared the incidence of unplanned extubation, stability of vital signs and oxygen saturation between a control group (n = 24) receiving routine care in a neonatal intensive care unit and an experimental group (n = 24) receiving routine care along with the use of the Endotracheal Tube Adjustable Stabilizing Set, developed by the researchers. The latter set comprises an endotracheal tube-holding cap, head-locked pillows, and an oxygen meter. Data were analyzed using descriptive statistics, t-tests, chi-square tests, and Fisher’s exact tests. Results show that the control group had an average tracheal tube insertion time of 78.94 hours, while the experimental group had an average of 39.35 hours. The incidence of unplanned extubation was 33.33% (8 cases) in the control group and 4.17% (1 case) in the experimental group. The unplanned extubation rate per 100 ventilator days was 4.41 times in the experimental group, significantly less than in the control group (23.84 times). The experimental group also exhibited significantly more time spent on vital signs and oxygen saturation within normal limits than the control group. In conclusion, using the Endotracheal Tube Adjustable Stabilizing Set in neonatal care can improve patient outcomes by reducing the incidence of unplanned extubation and stabilizing vital signs. This set has passed patentability evaluation for product design and enhances neonatal care by stabilizing endotracheal tubes, reducing slippage, and helping nurses provide more effective care. However, further testing in different settings with larger sample sizes and an equal average tracheal tube insertion time between the two groups is recommended to validate these findings.

Optimizing intubation technique using a single-use video laryngoscope: A comparative study in a simulation model.

Tracheal intubation poses a high risk of infection to medical staff due to Coronavirus disease 2019 (COVID-19) highly infectious nature. To mitigate this risk, various medical devices, including video laryngoscopy, have been developed to assist intubation. This study compared conventional laryngoscopy (Macintosh) and disposable video laryngoscopes (Medcaptain VS-10s and Honestmc Laryngoscope_LA10000) in terms of their use and operation processes. We designed a questionnaire to assess the operator perception of performing intubation with the devices, and statistical analysis was performed on 50 clinical staff members from 2 hospitals who had performed intubation or had learned intubation techniques. The primary outcomes were time to glottic visualization, intubation time, intubation success rate, distance between the operator and training model, and time from glottic visualization to tube insertion. The secondary outcomes were as follows: overall laryngoscope quality, operative feel, maneuverability, ease of use, and video quality. This study showed that video laryngoscopes were superior to conventional laryngoscopes in terms of quality, operative feel, and ease of use. When LA10000 was employed, the intubation success rate was higher, and the operator risk of infection was lower because of the greater distance from the training model. However, the use of video laryngoscopes requires appropriate education and training use of the devices. This study also demonstrated that when participants viewed a simple operation video prior to using video laryngoscopes, tube insertion time was shorter. Overall, video laryngoscopy can provide a safer and more convenient option for clinical medical personnel during pandemics.

Aqueous shunt exposure repair: outcomes and risk factors for recurrence.

To investigate the outcomes of aqueous shunt exposure repair and to identify risk factors for recurrent exposure after surgical repair. This is a retrospective interventional case series of consecutive patients who underwent repair of an exposed aqueous shunt. Demographic and clinical data were extracted from the patients' records and survival analysis was employed to determine the probability of survival of the repair without further exposure. Cox proportional regression analysis was utilised to identify potential risk factors for failure of the repair surgery. Seventy-six eyes of 76 patients were included in the study. The probability of survival without further exposure was 76.2% (CI 66.9-86.8%), 72.7% (CI 62.8-84.1%) and 54.7% (40.5-73.7%) at 1,2 and 4 years, respectively. No eye in which the tube was repositioned in the anterior chamber or in the sulcus (n = 9; 11.8%) developed a recurrence of the exposure. A shorter interval from the time of tube insertion to the repair surgery (HR 2.87 [CI 1.11-7.39]; p = 0.03; reference longer interval), a history of previous surgical revision (HR 3.06 [1.15-8.12]; p = 0.02; reference no prior revision) and the use of a human pericardial donor patch at the time of revision (HR 3.43 [1.16-10.13]; p = 0.03; reference other than pericardium) was associated with an increased risk of exposure recurrence. Aqueous shunt exposure revision is associated with reasonable mid and long term success. A shorter interval from tube insertion to exposure revision, previous revisions and the use of a human pericardium patch were associated with increased risk of failure.

Development and validation of a predictive model for double-J stent encrustation after upper urinary tract calculi surgery

The study is aimed to establish a predictive model of double-J stent encrustation after upper urinary tract calculi surgery. We collected the clinical data of 561 patients with indwelling double-J tubes admitted to a hospital in Shandong Province from January 2019 to December 2020 as the modeling group and 241 cases of indwelling double-J tubes from January 2021 to January 2022 as the verification group. Univariate and binary logistic regression analyses were used to explore risk factors, the risk prediction equation was established, and the receiver operating characteristic (ROC) curve analysis model was used for prediction. In this study, 104 of the 561 patients developed double-J stent encrustation, with an incidence rate of 18.5%. We finally screened out BMI (body mass index) > 23.9 (OR = 1.648), preoperative urine routine white blood cell quantification (OR = 1.149), double-J tube insertion time (OR = 1.566), postoperative water consumption did not reach 2000 ml/d (OR = 8.514), a total of four factors build a risk prediction model. From the ROC curve analysis, the area under the curve (AUC) was 0.844, and the maximum Oden index was 0.579. At this time, the sensitivity was 0.735 and the specificity was 0.844. The research established in this study has a high predictive value for the occurrence of double-J stent encrustation in the double-J tube after upper urinary tract stone surgery, which provides a basis for the prevention and treatment of double-J stent encrustation.

Long-term outcomes of EUS-guided balloon-occluded gastrojejunostomy bypass for malignant gastric outlet obstruction (with video)

Endoscopic ultrasonography-guided gastroenterostomy (EUS-GE) is a minimally invasive technique for gastric outlet obstruction (GOO). EUS-guided balloon-occluded gastrojejunostomy bypass (EPASS) aims to improve stent deployment and minimize migration in EUS-GE. In this study, we evaluated the long-term outcomes of EPASS. We retrospectively analyzed 37 patients (mean age 71; 21 males) with symptomatic, non-refractory GOO who had undergone EPASS. EPASS achieved a 94.6 % (35/37) technical success rate including 2 cases of stent mis-deployment. The mean procedure time was 27.3 min, with a double-balloon tube insertion time of 10.4 min. Initial GOO scores improved from 0.43 to 2.14 and 2.60 at 7 and 28 days post-EPASS, respectively. The clinical success rate was 89.2%. The rate of adverse events, including fever and abdominal pain, was 16.2%. The mean overall survival post-EPASS was 193.5 days, with no stent occlusion or migration (100% patency). EPASS demonstrates safety and reliability in EUS-GE, offering a viable option for symptomatic malignant GOO treatment.

Modified Intravenous Cannula Ventilation Tubes for Otic Barotrauma Prevention.

Objectives: Middle ear barotrauma is a common complication of hyperbaric oxygen therapy (HBOT). Tympanostomy tube placement prevents barotrauma by facilitating middle ear equalization. We describe variations on techniques published by Mooney et al and Zhang et al for placing modified peripheral intravenous cannula (PIVC) ventilation tubes, which can be performed at the bedside under topical anesthesia. We aim to evaluate the safety and efficacy of this technique when performed to prevent otic barotrauma in patients undergoing HBOT. Methods: We performed an analytical observational study at a tertiary metropolitan Australian hospital with a state-wide adult hyperbaric service between 2018 and 2022. Patients were identified via unit audits. Patient, HBOT, and procedural factors were analyzed against complications using Fisher's exact test with Bonferroni correction and simple logistic regression. Results: Over 4 years, 112 patients (220 ears) underwent modified PIVC ventilation tube insertion. Mean age was 58.6 years (95% CI: 55.7-61.6, SD: 15.9). Thirty-eight patients (33.9%) were female, 74 (66.1%) were male. Thirty-four ears (15.5%) had preexisting barotrauma at the time of tympanostomy tube insertion. Patients underwent a mean of 11.5 dives (95% CI: 9.0-14.0, SD: 13.4), with ventilation tubes being required for a mean of 15.0 days (95% CI: 9.0-14.0, SD: 24.0) to complete HBOT. Fourteen ventilation tubes (6.4%) developed blockage during HBOT, and 12 (5.5%) prematurely extruded. Sixteen ears (7.3%) required reinsertion of ventilation tubes. Nine ears (4.1%) suffered barotrauma despite ventilation tube insertion. Conclusions: Otic barotrauma prophylaxis is paramount for safety during HBOT. We describe a safe, effective, and convenient technique for barotrauma prevention using modified PIVCs.

Application and effectiveness of an improved endoscopically guided nasojejunal tube placement technique in critically ill patients: a retrospective cohort study.

The endoscopic nasojejunal (NJ) placement plays a pivotal role in the nutritional support of critically ill patients. However, the conventional endoscopy-guided tube insertion method presents issues of excessive procedural duration. We have enhanced the traditional endoscopy-guided catheter placement method, enabling a faster and more convenient catheter insertion. We improved the traditional endoscopically guided technique by incorporating an extra silk thread knot at the 25 cm mark on the jejunal segment of the NJ tube to assist endoscopists in accurate tube placement. We conducted the improved NJ tube placement on critically ill patients in need of enteral nutrition (EN). Laboratory data were retrospectively collected before and after the 7-day period of NJ tube placement and EN treatment to evaluate the effectiveness and safety of the improved method. A total of 88 critically ill patients, with an average age of 59.6±15.5 years, and a male ratio of 86.4%, who underwent the improved NJ tube placement method were enrolled into analysis finally, achieving a 100% success rate of NJ tube insertion. The average time for tube insertion was 5.9±2.2 min, with a mean insertion depth of 108.8±12.5 cm. The EN tolerance score was 0.79±0.98. Following 7 days of EN therapy, the patients showed significant improvement in serum albumin levels compared to baseline (36.42 vs. 33.66 g/L, P<0.001). The improved endoscopically guided NJ tube placement technique is a rapid and safe procedure with excellent patient tolerance. It significantly improves the nutritional status of critically ill patients and facilitates the administration of EN, which requires further validation through randomized controlled trials.

Anaesthetic induction with alfaxalone in Jungle Carpet Python (Morelia Spilota Cheynei)

The aim of this investigation was to assess the clinical use of alfaxalone as a short-acting anaesthetic agent for induction to inhalation anaesthesia in jungle carpet pythons (Morelia spilota cheynei). Ten healthy, captive, sub-adult jungle carpet pythons (1.1±0.32 kg bw) were anaesthetised using a dose of 10mg/kg of alfaxalone, administered intravenously to the ventral tail vein. Heart rate (HR) and respiratory rate (RR) were recorded before administration (T0), and every 5 minutes until the snakes fully recovered from the anaesthesia. The induction time, time of tail-pinch reflex loss, tracheal tube insertion time, interval of deep anaesthesia, and the time of full recovery were recorded. The induction time occurred within 3.1±0.8 minutes. The tail-pinch reflex loss was lost within 5.6±0.7 minutes. The mean tracheal tube insertion time, the interval of deep anaesthesia, and the time of full recovery were 6.9±0.9 minutes, 18.8±4.7 minutes, and 36.7±11.4 minutes, respectively. A prolonged time of full recovery was recorded in two snakes (61.3 and 62.6 minutes, respectively). Their mean heart rate was statistically higher (P&lt;0.05) at T5, T15 and T20 when compared with the basal HR at T0. The respiratory rate of the snakes dropped at T5 and was statistically lower (P&lt;0.05) from T5 until T20 when compared with RR at all other time points. In two snakes apnoea was recorded at T5. Intravenous administration of alfaxalone proved to be a valuable method of induction, suitable for a subsequent inhalation anaesthesia in jungle carpet pythons.

Comparative evaluation of the clinical performance of supraglottic airways- Supreme laryngeal mask airway, I gel and baska mask

There are no studies comparing Supreme laryngeal mask airway (LMA), I gel and Baska mask in Indian population. A comparison of the clinical performance of Supreme LMA, I gel and Baska mask was undertaken in this randomized controlled study.The present research was undertaken in 75 patients aged 18 to 60 years who underwent elective surgery for less than 3-hour duration under general anaesthesia. The patients were randomly divided into three groups; Supreme LMA, I gel, and Baska mask. The oropharyngeal leak pressure (OLP) after 30 minutes to loss of spontaneous respiration was the primary objective, whereas the secondary objectives were attempts required for insertion of LMA, ease of gastric tube insertion, time required for gastric tube insertion and post-operative morbidity. The mean OLP of Baska mask group was (28.2 cm HO) as compared to Supreme LMA (25.3 cm HO) and I-gel (24.1 cm HO) groups (p-value = 0.0001). The mean gastric tube insertion time of Baska mask group was (20.7 s) as compared to Supreme LMA (6.7 s) and I-gel (9.6 s) groups (p-value = 0.0001). The three groups were comparable with regards to the number of attempts required, ease of gastric tube insertion and post-operative morbidity.A higher OLP was observed in Baska mass group as compared to Supreme LMA and I-gel. The three devices were similar in terms of attempts required for insertion, ease of gastric tube insertion and post-operative morbidity.

Comparison of C-MAC Miller blade video laryngoscope with conventional Miller blade in infants undergoing elective surgery- A prospective randomised trial.

Endotracheal intubation (ET) in infants is considered a challenging task over the decades. Infants have short safe apnoea time, and this difficulty has been vanquished to some extent by using the videolaryngoscopes (VLs), but there exists a dearth of research particularly in this vulnerable subset. Therefore, this trial was conducted to evaluate intubation times obtained with C-MAC VL and conventional Miller laryngoscopes in infants. A total of 80 infants aged between 1 month and 1 year with American Society of Anesthesiologists physical status I-II requiring ET were randomised in two groups; the C-MAC VL or Miller laryngoscope ML. Anaesthesia was induced with sevoflurane 1-8% and atracurium 0.5 mg/kg IV. The primary outcome was evaluated as the total time taken to intubate. Secondary outcomes were time to achieve best glottic view (TBGV), tube insertion time (TIT), percentage of glottic opening (POGO) score, number of attempts and intubation difficulty score (IDS). The median (interquartile range) of time taken for ET was less in VL; 22.5 (20.75-26) compared to ML; 26 (21.75-31). TBGV was achieved early in VL group than the ML group (6.03 ± 1.33s/7.88 ± 2.44) respectively (P-value < 0.001). POGO was better in VL (99.12 ± 4.795s) compared to ML (85.50 ± 31.13s). IDS was less in the VL group (0.07 ± 0.27) than in ML (0.70 ± 1.14). Other parameters, such as the number of attempts, bougie usage, adverse effects and TIT, were comparable across the two groups. When compared to the ML group, the C-MAC VL group exhibited a decreased intubation time, early TBGV, better POGO score, reduced IDS and subjective intubation difficulty. As a result, we consider VL to be a more efficacious device for intubating the trachea in infants.

A prospective randomized study of different height of operation table for tracheal intubation with videolaryngoscopy in ramped position

BackgroundPrevious studies have reported that the ramped position provides a better laryngoscopic view, reduces tracheal intubation time, and increases the success rate of endotracheal intubation. However, the patient’s head height changes while in the ramped position, which in turn changes the relative positions of the patient and intubator. Thus, making these changes may affect the efficiency of tracheal intubation; however, few studies have addressed this problem. This study analyzed intubation time and conditions during tracheal intubation using videolaryngoscope in the ramped position.MethodsThis prospective study included 144 patients who were scheduled to receive general anesthesia for surgeries involving orotracheal intubation. The participants were randomly allocated to either the nipple or umbilical group according to the table height. Mask ventilation was assessed using the Warters grading scale. Tracheal intubation was performed using a McGrath MAC laryngoscope. The total intubation time, laryngoscopy time, tube insertion time, and difficulty of intubation (IDS score) were measured.ResultsThe umbilical group had a significantly shorter laryngoscopy time (10 ± 3 vs. 16 ± 4 s), tube insertion time (18 ± 4 vs. 24 ± 6 s), and total intubation time (28 ± 5 vs. 40 ± 7 s) compared to the nipple group. No significant difference in the difficulty of mask ventilation was observed between the two groups. The IDS score was higher in the nipple than umbilical group.ConclusionThe lower (umbilical) table level reduced the intubation time and difficulty of videolaryngoscopy compared to the higher (nipple) table level.Trial registrationThis study was registered at KCT0005987, 11/03/2021, Retrospectively registered.

Impact of choice of nostril on nasotracheal intubation when using video rigid stylet: a randomized clinical trial

BackgroundPatients undergoing oral and maxillofacial surgeries under general anesthesia usually require nasotracheal intubation. When presented with patients with equally patent nostrils, selection of the nostril to use for intubation is an important decision for facilitating intubation. The objective of this trial is to determine whether choice of nostril impacts nasotracheal intubation when using a video rigid stylet in patients undergoing oral and maxillofacial surgery.MethodsFifty patients scheduled for elective oral and maxillofacial surgery requiring nasotracheal intubation were randomly allocated into two groups to undergo nasotracheal intubation through the left nostril (Group L, n = 25) or the right nostril (Group R, n = 25). Intubation was performed by experienced anesthesiologists using a video rigid stylet. The primary endpoint was time to successful intubation, which was defined as the duration from when the tip of the stylet-tube assembly entered the selected nostril to when the tube entered the trachea. Secondary outcomes included: length of time for device insertion; length of time for tube insertion; total success rate; first-attempt success rate; number of intubation attempts; requirement of airway assisted maneuvers; incidence and severity of epistaxis. Intubation-related adverse events were monitored for up to postoperative 24 h.ResultsMedian time (interquartile range) to tracheal intubation was 25.3 seconds (20.7 to 27.6) in Group L and 26.8 seconds (22.5 to 30.0) in Group R (median difference (MD) = 1.9; 95% confidence interval (CI) –1.8 to 5.7, P = 0.248). Nasotracheal intubation was successful in all patients in both groups and the first-attempt success rates in both groups were similar (Group L: 96% (24/25); Group R: 96% (24/25); relative risk (RR) 1.0; 95% CI 0.9 to 1.1; P > 0.999). No significant difference of requirement of assisted maneuvers was noted between the two groups (Group L: 36% (9/25); Group R: 28% (7/25); RR 0.8; 95% CI 0.3–1.8; P = 0.544). Furthermore, all patients showed a high quality of visualization of the glottis (Cormack and Lehane Grade I). For safety outcomes, the incidence and severity of epistaxis during intubation was comparable between the two groups. There were no significant differences between the selection of nostrils and intubation-related adverse events up to 24 h after surgery.ConclusionsWhen considering which nostril to use for intubation with video rigid stylet, either nostril can be used similarly.Trial registrationClinicaltrials.gov. Identifier: NCT05218590.

Effectiveness of Perioperative Cardiopulmonary Rehabilitation in Patients With Lung Cancer Undergoing Video-Assisted Thoracic Surgery.

ObjectivesPatients with lung cancer pose a high risk of morbidity and mortality after lung resection. Those who receive perioperative cardiopulmonary rehabilitation (PRCR) have better prognosis. Peak oxygen consumption (peak VO2), VO2 at the ventilatory threshold (VO2 at VT), and slope of minute ventilation to carbon dioxide production (VE/VCO2 slope) measured during pre-surgical cardiopulmonary exercise testing (CPET) have prognostic values after lung resection. We aimed to investigate the influence of individualized PRCR on postoperative complications in patients undergoing video-assisted thoracic surgery (VATS) for lung cancer with different pre-surgical risks.MethodsThis was a retrospective study. We recruited 125 patients who underwent VATS for lung cancer between 2017 and 2021. CPET was administered before surgery to evaluate the risk level and PRCR was performed based on the individual risk level defined by peak VO2, VO2 at VT, and VE/VCO2 slope, respectively. The primary outcomes were intensive care unit (ICU) and hospital lengths of stay, endotracheal intubation time (ETT), and chest tube insertion time (CTT). The secondary outcomes were postoperative complications (PPCs), including subcutaneous emphysema, pneumothorax, pleural effusion, atelectasis, infection, and empyema.ResultsThree intergroup comparisons based on the risk level by peak VO2 (3 groups), VO2 at VT (2 groups), and VE/VCO2 slope (3 groups) were done. All of the comparisons showed no significant differences in both the primary and secondary outcomes (p = 0.061–0.910).ConclusionPatients with different risk levels showed comparable prognosis and PPCs after undergoing CPET-guided PRCR. PRCR should be encouraged in patients undergoing VATS for lung cancer.

Comparison of self-assembled video laryngoscope versus McGrath MAC®: A randomised controlled trial.

ABSTRACTBackground and Aims:Video laryngoscopy highly improves the success rate for endotracheal intubation. However, commercially available video laryngoscopes such as McGrath MAC® can be costly. An economical video laryngoscope was assembled by attaching a fibreoptic videoscope into a Macintosh laryngoscope. This randomised study aimed to compare the intubation time of this self-assembled modified Macintosh video laryngoscope (SAM-VL) and McGrath MAC® (McGrath).Methods:This study enroled 62 adults scheduled for elective surgery under general anaesthesia with endotracheal intubation. The primary outcome was total intubation time. Secondary outcomes were the time for glottic visualisation (time A), time for tube insertion after glottic visualisation (time B), first-attempt intubation success rate, degree of glottic visualisation, and need for backward, upward, rightward pressure (BURP) assistance, complications, and user satisfaction. The tests used were: Kolmogorov-Smirnov and the Mann-Whitney test to analyse the data’s distribution and the primary outcome, respectively.Results:The median total intubation time in the SAM-VL group versus the McGrath was 63 s (27–114s) versus 74 s (40–133s), respectively (P = 0.032). Intubation time B was significantly faster, while the score of glottic visualisation and BURP assistance was significantly higher in the SAM-VL group. The differences in the rate of successful first attempts and complications were not statistically significant. SAM-VL users rated the ease of blade insertion and manoeuvrability, degree of glottic visualisation, and overall rating as very high.Conclusion:Endotracheal intubation using self-assembled modified video laryngoscope is faster and allows better glottis visualisation than McGrath MAC®.

Factors influencing surgeon decision-making by measuring waiting time for pediatric ventilation tube insertions.

The surgeon and physician's decision-making may be influenced by many factors. The clinical practice guideline suggested that watchful waiting for 3 months should be the initial management for pediatric otitis media with effusion. The waiting time of ventilation tube insertion for pediatric patients is a proper measurement for physician decision-making. This study investigated factors influencing the waiting time for pediatric ventilation tube insertion and to explore factors influencing physician decision-making. Information associated with all patients under 18 years of age who received ventilation tube insertions from July 1, 2000 to December 31, 2009 were retrieved and analyzed from a nationwide, population-based administrative database. The waiting time before ventilation tube insertions from the time of diagnosis of otitis media with effusion was recorded. Certain factors that would influence the waiting time were identified. At the same time, how these factors influenced clinical decision-making were also identified. The waiting time decreased as patient age increased (p < 0.001), and increased as the recent frequency of upper respiratory tract infection diagnosis increased (p < 0.001). Patients who received simultaneously bilateral ventilation tube insertions had shorter waiting time than those who had unilateral surgery (p < 0.01) and patients who had undergone ventilation tube insertions in a tertiary referral center generally had longer waiting times (p < 0.001). The waiting time of ventilation tube insertions for pediatric otitis media with effusion can be influenced by many factors. Patients with older age and undergone simultaneously bilateral ventilation tube insertion had shorter waiting time. Patients who had more upper respiratory tract infection episodes and who received ventilation tube insertions in a tertiary referral center setting were subject to longer waiting times.

Adenoidectomy may decrease the need for a third set of tympanostomy tubes in children

ObjectiveTo determine whether removing or retaining adenoids at the time of placement of a second set of ear tubes impacts the need for a third set of ear tubes later in childhood. Study designSingle-institution retrospective case series. SettingTertiary academic university hospital. MethodsWe identified pediatric subjects who had undergone a second ear tube placement between 1/1/17 and 9/1/19. Subjects were stratified into two groups: 1) adenoids removed at time of second tympanostomy tube insertion (TT+A) and 2) adenoids retained at time of second tympanostomy tube insertion (TT-A). A subset of children less than age 4 was also studied independently. The primary outcome was number of patients requiring a third set of tympanostomy tubes. ResultsA total of 136 subjects met inclusion and exclusion criteria. Among children less than 4 years of age (n = 99), the incidence of requiring a third set of tubes was significantly lower in the TT+A group <4 (12.8%; 6/47) compared to the TT-A group <4 (44.2%; 23/52) (p = 0.0008) with an odds ratio of 0.18 (95%CI 0.067–0.51) and number needed to treat of 3.2. ConclusionPerforming adenoidectomy in children less than 4 years of age at the second tympanostomy procedure was associated with a reduced incidence of requiring a third set of ear tubes.

Assessing the use of telehealth for the surgical management of recurrent otitis media

ObjectiveTo compare the incidence of middle ear effusion (MEE) at the time of bilateral tympanostomy tube insertion (BTI) for recurrent acute otitis media (rAOM) patients initially seen in-office or via telehealth. MethodsAfter obtaining IRB approval from Nationwide Children's Hospital, a total of 524 patients evaluated for rAOM were retrospectively reviewed after being divided into two cohorts: those seen via a telehealth visit from April to June of 2020 (n = 140), and those seen via an in-person visit from April to June of 2019 (n = 384). Recommendation for BTI was captured for each patient following their visit. Clinical characteristics documented at the time of the visit, such as history of intramuscular (IM) antibiotic use and hearing or speech concerns were also captured to determine whether both telehealth and in-person cohorts were similar in clinical presentation. For BTI patients, the presence or absence of MEE in either ear at the time of BTI was recorded. Patients with cleft palate or prior BTI were excluded. Results51.43% (72/140) of patients in the telehealth cohort were recommended for BTI. Of those recommended, 87.50% (63/72) underwent BTI. Of these, 31.75% (20/63) had a MEE at the time of BTI. In the in-office cohort, 69.01% (265/384) of patients were recommended for BTI. Of those recommended, 92.83% (246/265) underwent BTI. Of these, 69.92% (172/246) had a MEE at the time of BTI. ConclusionThere were significantly less middle ear effusions in the telehealth cohort compared to the in-office cohort (p < 0.0001). It is well understood that telehealth is limited in its physical exam capabilities. It is possible that the use of telehealth for the surgical management of rAOM may lead to more procedures on patients without MEE.

Comparison of LMA Supreme, i-gel, and Baska Mask for Airway Management during Laparoscopic Cholecystectomy: A Prospective Randomized Comparative Study from North India.

Background:The supraglottic airway device (SAD) has proved to be an appropriate alternative to endotracheal intubation in laparoscopic surgeries owing to various advantages, namely, decreased airway manipulation and stable hemodynamics.Aims:We compared the efficacy in terms of oropharyngeal leak pressure (OLP) and safety of laryngeal mask airway (LMA)-Supreme (LMA-S), i-gel, and Baska mask in patients undergoing laparoscopic cholecystectomy.Settings and Design:Ninety patients posted for elective laparoscopic cholecystectomy were selected for a prospective randomized comparative study in a tertiary care center.Materials and Methods:The study comprised three groups of 30 each based on the different SADs used Group-LS with LMA-Supreme, Group-IG with i-gel, and Group-BM with Baska mask. The secondary objectives were device insertion time, ease of insertion, changes in the peak airway pressure (PAP), heart rate, mean arterial pressure, and airway complications (sore throat, dysphagia. dysphonia, lip/tongue or dental injury, etc.) between three groups.Statistical Analysis:The quantitative data were analyzed using the one-way analysis of variance test and Bonferroni post hoc multiple comparison test. Qualitative data were compared using Chi.squared testResults:OLP was significantly higher (P = 0.005) in the Baska mask than i-gel and LMA-S groups just after insertion and during carboperitonium. There was no significant difference in time for device insertion, number of attempts, ease of insertion, and use of manipulation (P > 0.05). However, the gastric tube insertion time was significantly lower in Group BM (9.59 ± 2.78) than Group IG with 12.79 ± 3.47 and Group LS with 10.84 ± 3.68 (P < 0.05). There were no significant differences between the groups with regard to changes in the PAP, heart rate, mean arterial pressure at different time intervals, and complications.Conclusion:Baska mask provided a significantly higher OLP compared to i-gel and LMA-S without significant airway morbidity in laparoscopic surgeries.
