Background: Truview PCD video laryngoscope is particularly planned to assist in locating the endotracheal tube in addition to observe the admission of the tube into the glottis. The present study was performed to assess the outlook of glottic opening and relief of intubation between the Truview PCD laryngoscope and Macintosh laryngoscope in patients undergoes general anaesthesia. Subjects and Methods: Ninety patients of ASA grade 1 and 2 aged 18-60 years, posted for elective surgery under general anaesthesia needing endotracheal intubation were arbitrarily allocated into group 1 (Truview PCD laryngoscope n=45) and group 2 (Macintosh laryngoscope n=45). The two groups were compared for demographic data, intubation difficulty score, Cormack-Lehane grade, time to intubate, number of intubation attempts and hemodynamic parameters. Conclusion: Truview PCD can be measured as an alternate intubation device, especially in difficult intubation conditions.

Abstract Background: We compared intubation conditions, intubation times, and hemodynamic response with the GlideScope video laryngoscope or the Macintosh direct laryngoscope in children older than one year. Methods: In total, 80 patients aged 1–12 years, scheduled to undergo elective surgery under general anesthesia with endotracheal intubation were included in a prospective, randomized trial.After standard anesthesia induction, patients were randomized into two groups.The group G patients(n = 40) were intubated with the GlideScope and the group M patients(n = 40) were intubated with the Macintosh laryngoscope.Intubation time, number of attempts,Cormack–Lehane score, airway maneuvers,visual analog score were recorded. Hemodynamic variables were recorded before and after anesthesia induction, at intubation, and one,three, and five minutes after intubation. Results: The demographic data and operation time were similar between the two groups. The intubation time was longer in Group G. The incidence of Cormack–Lehane score 1 was higher in Group G and that of Cormack–Lehane score 2 was higher in Group M. The hemodynamic parameters were similar between the two groups. Conclusion: We concluded that the GlideScope video laryngoscope provided better glottis visualization, but prolonged intubation time. No beneficial hemodynamic effect was found with the video laryngoscope.

Background. Video laryngoscopes provide better view and can improve ease of intubation compared with standard laryngoscopes. Methods. A prospective randomized study was done on 60 patients, 18 to 65 years old, comparing McGrath video laryngoscope and Macintosh laryngoscope. The aim was to compare the ease, efficacy, and usability of them during routine airway management. The primary endpoint was duration of intubation and the secondary endpoints were Cormack and Lehane grade of laryngoscopic view, number of intubation attempts, and incidence of complications. Results. There was an increase in total duration of intubation with McGrath video laryngoscope with 42.9 ± 19.5 seconds compared to Macintosh laryngoscope with 17.9 ± 4.6 seconds. In Macintosh group, 73.3% had grade I, 20% had grade II, and 6.7% had grade III Cormack Lehane view, while in McGrath group, 83.3% had grade I, 13.3% had grade II, and 3.3% had grade III. In McGrath group, 6 patients (20%) required more than 120 seconds to get intubated and only 73.3% were intubated in 1 attempt, while patients in Macintosh group had 100% successful intubation in 1 attempt. Pharyngeal trauma was seen with McGrath videolaryngoscopy. Conclusion. Duration of laryngoscopy, intubation, and total duration of intubation were significantly higher in McGrath group than in Macintosh group. McGrath group required a higher number of intubation attempts.

Background: Arterial blood pressure is one of the most commonly variables monitored during anesthetic procedures in veterinary patients. The most reliable method for measuring arterial blood pressure in dogs and cats is the direct (invasive) method. However, the oscillometric method is less complex and more practical for clinical routine in small animals. Nevertheless, oscillometric monitors present great variability in accuracy. The present study aimed to determine the accuracy of the Delta Life DL 1000 oscillometric monitor for measurement of systolic, mean and diastolic blood pressures (SAP, MAP and DAP, respectively) in anesthetized dogs of different weight ranges.Materials, Methods & Results: This study was approved by the Institutional Ethics Committee of Animal Use. Fifteen female dogs of different breeds, weighing 11.6 ± 10.0 kg and with a mean age of 48 ± 51 months were used. All animals were scheduled for elective surgery under general anesthesia in the Institution Veterinary Hospital. Dogs were anesthetized with morphine, propofol and isoflurane and had one 20 or 22 gauge catheter introduced into the dorsal pedal artery for continuous, invasive monitoring of SAP, MAP and DAP. A blood pressure cuff was positioned over the middle third of the radius and connected to Delta Life DL 1000 monitor. Oscillometric readings of SAP, MAP and DAP were registered every 5 minutes, and invasive values were simultaneously recorded. Values obtained with both methods were compared (invasive versus oscillometric) by use of the Bland Altman method to determine the bias, standard deviation of bias and 95% limits of agreement. The percentages of errors between the methods within 10 mmHg and within 20 mmHg were calculated. The results obtained were compared with the criteria from the American College of Veterinary Internal Medicine (ACVIM) for validation of indirect methods of arterial blood pressure measurement. Data were stratified into two groups according to the weight: < 10 kg (Group 1; n = 9); and ≥ 10 kg (Group 2; n = 6). In Group 1, 119 paired measurements were obtained, four of which classified as hypotension (SAP < 90 mmHg), 98 as normotension (SAP from 90 to 140mmHg) and 17 as hypertension (SAP > 140 mmHg). Bias (± SD) values in Group 1 were as follows: SAP, 5.2 ± 18.1 mmHg; MAP, -3.4 ± 17.2 mmHg; and DAP, 12.0 ± 17.5 mmHg. The percentages of errors within 10 mmHg were 40.3% for SAP; 45.4% for MAP and 28.6% for DAP. The percentages of errors within 20 mmHg were 72.3% for SAP, 84.0% for MAP and 68.1% for DAP. In Group 2, 66 paired measurements were obtained, nine of which classified as hypotension, 56 as normotension and one as hypertension. Bias (± SD) in Group 2 were as follows: SAP, 13.6 ± 14.3 mmHg; MAP, -1.1 ± 13.5 mmHg; and DAP, 8.2 ± 16.0 mmHg. The percentages of errors within 10 mmHg were 33.3% for SAP, 77.3% for MAP and 33.3% for DAP. The percentages of errors within 20 mmHg were 65.1% for SAP, 92.4% for MAP and 83.4% for DAP.Discussion: Based on the results of this study and reference criteria from the ACVIM, the Delta Life DL 1000 monitor had a poor accuracy for SAP, MAP and DAP and did not meet the criteria from the ACVIM in anesthetized dogs under 10 kg. Measurements of MAP in dogs ≥ 10 kg met the ACVIM criteria, but measurements of SAP and DAP did not. Based on the findings in this study, the DL 1000 oscillometric monitor is not recommended for blood pressure measurement in anesthetized dogs < 10 kg. In dogs ≥ 10 kg, measurements of MAP yielded acceptable values, but SAP and DAP measurements did not.

This prospective, randomized, double-blinded study evaluated the effect of the timing of ondansetron administration on its antiemetic efficacy in children undergoing elective strabismus surgery. One hundred and twenty children aged one to 15 years, ASA physical status 1 or 2, were randomly allocated to receive intravenous ondansetron 100 μg/kg either at induction (Group 1) or at the end of the surgery (Group 2). All patients had general anaesthesia induced and maintained with nitrous oxide and halothane, muscle relaxation with vecuronium, endotracheal intubation, reversal with neostigmine and glycopyrrolate, and pethidine 0.5 mg/kg analgesia. Episodes of nausea and vomiting were evaluated at 0 to 2, 2 to 6 and 6 to 24 hour intervals by a blinded observer. Demographic data, duration of anaesthesia, type of surgery, incidence of previous postoperative nausea or vomiting and motion sickness and number of patients who developed oculocardiac reflex requiring atropine treatment were similar in both groups. The incidence of emesis in the first 24 hours following surgery was similar in both groups (35% Group 1, 33.3% Group 2, P=1.00). Severity of emesis (median number of emetic episodes, rescue antiemetic requirement and mean time to the onset of first episode of emesis) and mean time to discharge from the post anaesthesia care unit were also similar in the two groups. We conclude that the timing of ondansetron administration either before or after the surgical manipulation of extraocular muscles had similar antiemetic efficacy following strabismus surgery in children.

SummarySixty-five patients primarily referred for erectile impotence were investigated. Information was obtained from patients and their partners. The demographic data are compared with those from a non-impotent psychiatric out-patient group, matched for age. Results indicate that impotent cases do not form a homogeneous population and can be classified into three fairly distinct groups. These groups differ in age, marital status, sex drive, pre-marital and post-marital relationships, duration of illness, etc. Group 1 develop impotence because of anxiety in sexual situations, Group 2 react to the sexual response and personality of their partners, while Group 3 decline, perhaps from inherent constitutional causes. Factors such as religious restrictions, sexual taboos, alcoholism and homosexuality do not appear to be of any aetiological importance.

Abstract Background and study aims Management of post-sleeve gastrectomy fistulas (PSGF) recently has evolved, resulting in prioritization of internal endoscopic drainage (IED). We report our experience with the technique in a tertiary center. Patients and methods This was a single-center, retrospective study of 44 patients whose PSGF was managed with IED, comparing two periods: after 2013 (Group 1; n = 22) when IED was used in first line and before 2013 (Group 2; n = 22) when IED was applied in second line. Demographic data, pre-endoscopic management, characteristics of fistulas, therapeutic modalities and outcomes were recorded and compared between the two groups. The primary endpoint was IED efficacy; the secondary endpoint was a comparison of outcomes depending on the timing of IED in the management strategy. Results The groups were matched in gender (16 female, 16 male), mean age (43 years old), severity of fistula, delay before treatment, and exposure to previous endoscopic or surgical treatments. The overall efficacy rate was 84 % (37/44): 86 % in Group 1 and 82 % in Group 2 (NS). There was one death and one patient who underwent surgery. The median time to healing was 226 ± 750 days (Group 1) vs. 305 ± 300 days (Group 2) (NS), with a median number of endoscopies of 3 ± 6 vs. 4.5 ± 2.4 (NS). There were no differences in number of nasocavity drains and double pigtail stents (DPS), but significantly more metallic stents, complications, and secondary strictures were seen in Group 2. Conclusion IED for management of PSGF is effective in more than 80 % of cases whenever it is used during the therapeutic strategy. This approach should be favored when possible.

Abstract BackgroundDuring endotracheal intubation training, only providing verbal guidance to students may result in inadequate recognition of the inner larynx and cause delays in mastering endotracheal intubation. Therefore, we introduced a deliberate practice approach to the education of residents in endotracheal intubation. For this purpose, a video laryngoscope was used to give the residents detailed feedback of the anesthesiology faculty. We hypothesized that if the anesthesiology faculty could provide sufficient and precise feedback of the larynx through the video monitor, the residents’ intubation skills would be retained for a more extended period.MethodsThis cluster randomized controlled study enrolled first-year residents who completed a two-month rotation at our department. Each rotation group (2–4 residents) was assigned to the Macintosh laryngoscope (ML) group or the McGRATH MAC video laryngoscope (MML) group. Endotracheal intubation skills were evaluated on a simulated mannequin immediately after the rotation, three months later, and six months later. The primary endpoint was the time required for intubation. The secondary endpoint was the percentage of glottic opening (POGO) score.ResultsForty-six residents participated in this study and were assigned to the ML group (n = 23) or the MML group (n = 23). The time required for intubation was significantly shorter in the MML group than in the ML group. The POGO score did not show any significant differences between the two groups; however, the POGO score of the MML group had a relatively narrower confidence interval than the ML group.ConclusionsWhen comparing endotracheal intubation training using the Macintosh laryngoscope and video laryngoscope, the McGRATH MAC video laryngoscope shortened the intubation procedure and facilitated long-term skill retention.Trial registrationClinical registry and trial number, URL: https://www.umin.ac.jp, UMIN000036643 date of registration: 2019/05/03, This study was retrospectively registered.
