Abstract Purpose Short Neck is a term used by anesthesiologists to describe one of the risk factors for difficult airway management. However, the term Short Neck is very subjective and has not been standardized. We attempt to quantify Short Neck.Methods A pilot prospective single blinded study was conducted at Hamad General Hospital, Doha, Qatar between March 2018 and October 2018. 97 adult patients scheduled for elective surgery under general anesthesia were recruited. Measurements of airway assessment, including neck length, were documented prior to anesthesia. The operators (anesthesiologists) were blinded. Intubation Difficulty Scale was used. All data were documented and analysed afterwards. Patients were of three groups according to Intubation Difficulty Scale (IDS): Group A: IDS 0, Group B: IDS >0 - ≤5 and Group C: IDS >5.Results Five patients (5.2%) with intubation difficulty score >5 have a mean neck length 7.6 cm. Short Neck was found to have a significant p value 0.022 within the three groups.Conclusions Patient's features relevant to airway assessment are rather difficult to quantify. This is the first reported attempt to obtain an objective value for Short Neck in routine airway assessment.

Background The ability of good glottis visualization during direct laryngoscopy is major determinant of easy tracheal intubation. Sniffing position for laryngoscopy is considered as gold standard and ideal position. Several studies have questioned the validation of sniffing potion. Objectives This study aims to compare relative efficacy of sniffing position and simple head extension for visualization of glottis during direct laryngoscopy. Methods Four hundred patients undergoing elective surgery under general anesthesia requiring endotracheal intubation were randomized into two groups and study was concluded. Glottic visualization was assessed using modified Cormack and Lehane classification. After laryngoscopy, tracheal intubation was performed and intubation difficulty scale was noted. Results Both the groups were comparable regarding glottis visualization. Both the groups were comparable in demographic profiles. All the intubation difficulty scale variables were comparable in both the groups except N3. Total Intubation Difficulty Score was better in sniffing position than in simple head extension group. Conclusion Glottic visualization and intubation difficulty score was better in sniffing position as compared to simple head extension.http://dx.doi.org/10.3126/kumj.v9i1.6265 Kathmandu Univ Med J 2011;9(1):58-63

Background and Objectives: Video laryngoscopy has been proven useful under difficult airway scenarios, but it is unclear whether anticipated improvement of visualization is related to specific difficult intubation prognostic factors. The present study evaluated the change in laryngoscopic view between conventional and C-MAC® laryngoscopy and the presence of multiple difficult intubation risk factors. Materials and Methods: Patients scheduled for elective surgery with >2 difficult intubation factors, (Mallampati, thyromental distance (TMD), interinscisor gap, buck teeth, upper lip bite test, cervical motility, body mass index (BMI)) were eligible. Patients underwent direct laryngoscopy (DL) followed by C-MAC™ laryngoscopy (VL) and intubation. Change of view between DL and VL, time for best view, intubation difficulty scale (IDS) and correlation between prognostic factors, laryngoscopic view improvement, and IDS were measured. Results: One-hundred and seventy-six patients completed the study. VL lead to fewer Cormarck–Lehane (C/L) III-IV, compared to DL (13.6% versus 54.6%, p < 0.001). The time to best view was also shorter (VL: 10.82 s, DL: 12.08 s, p = 0.19). Mallampati III-IV and TMD ≤ 6 cm were related to improvement of C/L between DL and VL. Logistic regression showed these two factors to be a significant risk factor of the glottis view change (p = 0.006, AUC-ROC = 0.57, 95% CI: 0.47–0.66). 175/176 patients were intubated with VL. 108/176 were graded as 0 < IDS ≤ 5 and 12/176 as IDS > 5. IDS was only correlated to the VL view (p < 0.0001). Conclusion: VL improved laryngoscopic view in patients with multiple factors of difficult intubation. Mallampati and TMD were related to the improved view. However, intubation difficulty was only related to the VL view and not to prognostic factors.

The purpose of this study was to determine changes in the hypoglossal nerve function after suspension laryngoscopy with needle electromyography of the tongue. This study also attempted to determine the possible relationship between the predictive factors of intubation difficulty by using the intubation difficulty scale, which was introduced by Adnet et al., duration of suspension laryngoscopy and changes in hypoglossal nerve function after suspension laryngoscopy. The study was performed on 39 patients who underwent suspension laryngoscopy for benign glottic pathology. Pre-operative airway assessment was evaluated by the intubation difficulty scale and the duration of suspension laryngoscopy was recorded. Needle electromyography of the tongue was performed three or four weeks after the suspension laryngoscopy. After needle electromyography of the tongue, increased polyphasia was found in 13 patients (33 per cent), bilaterally in three of them. The interference pattern was reduced in two of these 13 patients. There was no statistically significant difference in predictive factors of intubation difficulty and the duration of the operation between these 13 patients with increased polyphasiaand the remaining 26 patients with completely normal electromyography findings. These findings show that, in spite of normal clinical tongue function, subclinical changes can be detected by needle electromyography of the tongue after suspension laryngoscopy.

Abstrak          Penggunaan Propofol untuk induksi pada general anestesi dapat menyebabkan  hipotensi akibat vasodilatasi arteri dan vena terutama vena kapasitan ditungkai. Manuver elevasi tungkai dapat mempertahankan stabilitas hemodinamik dengan meningkatkan aliran balik vena ke jantung dan mengurangi penumpukan darah di vena kapasitan tungkai. Penelitian ini dirancang dengan menggunakan cara Open Randomized Control Trial. Subyek penelitian adalah 184 sampel pasien dewasa ASA I-II yang menjalani operasi elektif dengan menggunakan general anestesi dengan induksi propofol. Kelompok sampel penelitian dibagi dalam dua kelompok masing-masing berjumlah 92 orang. Setelah prabeban cairan RL 10 cc/kgbb dan pemberian fentanyl 2 mcg/kgbb dan midazolam 0,05 mg/kgbb maka kelompok A dilakukan elevasi tungkai 45º satu menit sebelum induksi propofol dan dipertahankan sampai penelitian selesai. Sedangkan kelompok B tidak dilakukan elevasi tungkai. Data yang dikumpulkan dianalisa dengan uji t tes. Untuk data proporsi dilakukan analisa dengan tes chi-square. Dari data demografi tidak didapatkan perbedaan yang bermakna secara statistik (p>0,05) antara kedua kelompok penelitian kecuali untuk BMI (p<0,05). Insidensi hipotensi  menit pertama pasca induksi propofol pada kelompok A (elevasi tungkai) secara signifikan lebih rendah (12%) dibanding kelompok kontrol B  (27,2%) (p=0,016; p < 0,05). Pada menit ketiga pasca induksi juga didapatkan insidensi hipotensi kelompok A  (15,2%) signifikan lebih rendah dibanding kelompok B (23,9%) (p= 0,014; p < 0,05). Elevasi tungkai 45 derajat efektif dalam menurunkan insidensi hipotensi pasca induksi propofol.  Kata kunci: propofol, hipotensi, elevasi tungkai AbstractThe induction of general anaesthesia with propofol may induce of considerable degree of hypotension that has been atributed to decrease in systemic vascular resistance  caused by combination of venous and arterial vasodilatation. It will produce a shifting  of blood to venous reservoir, especially capacitance venule of legs. Leg elevation can provide hemodynamic stability by increases cardiac preload and recruits blood contained in the venous reservoir. This is Open Randomized Control Trial include 184 elective surgery patients with American Society of Anaesthesiologist (ASA) physical status I and II. Anesthesia  was induced with propofol. Patients were randomly allocated into two groups with 92 patients in each. All the patients received Ringer’s Lactate (10 ml/kg) and premedicated with fentanyl (2 mcg/kg) and midazolam (0,05 mg/kg) before induction of anesthesia. Group A was performed passive leg raising 45 degree 1 minute before injection of propofol until  the end of study and group B (control) did not receive any maneuver. Parametric data were analyzed with t-test and categorical data was done by using Chi-square test. A p value of less than 0,05 was consider significant. Demografic characteristics (age, sex, body weight and height) and  baseline haemodynamic parameters of the patients were similar in two groups (p > 0.05) except for BMI (p < 0.05) . The incidence of hypotension was significantly lower in group A (12 %, ) than group  B (27,2%) at the first minute after propofol  injection, p value = 0.016 (p < 0,05). In the third minute, incidence of hypotension was also significantly lower in group A (15,2%) than group B (23,9%), p value = 0,014 (p < 0,05). Leg elevation maneuver 45º significantly decrease incidence of hypotension after propofol induction. Keywords: Propofol, hypotension, leg elevation

Background The WuScope is a rigid, fiberoptic laryngoscope designed to facilitate tracheal intubation without the need for head extension. The study evaluated the WuScope in anesthetized patients with neck immobilization. Methods Patients were randomized to one of two groups: those receiving fiberoptic laryngoscopy (WuScope, n = 43) and those receiving conventional laryngoscopy (Macintosh blade, n = 44). Manual in-line stablization of the cervical spine was done during intubation. Seven parameters of intubation difficulty were measured (providing an intubation difficulty scale score): number of operators, number of attempts, number of techniques, Cormack view, lifting force, laryngeal pressure, and vocal cord position. Results Successful intubation occurred in 95% of patients in the fiberoptic group and in 93% of patients in the conventional group. There were no differences in number of attempts. In the fiberoptic group, 79% of patients had an intubation difficulty scale score of 0, representing an ideal intubation: that is, one performed by the first operator on the first attempt using the first technique with full glottic visualization. Only 18% of patients in the conventional group had an intubation difficulty scale score of 0 (P &lt; 0.001). More patients had Cormack grade 3 or 4 views with conventional than with fiberoptic laryngoscopy (39 vs. 2%, P &lt; 0.001). Intubation times in patients with one attempt were slightly longer in the fiberoptic (median, 25th-75th percentiles: 30, 23-53 s) compared with the conventional group (24, 17-30 s, P &lt; 0.05). Corresponding times in patients requiring &gt; one attempt were 155 (range, 112-201) s and 141 (range, 95-186) s in the fiberoptic and conventional groups, respectively (P value not significant). Conclusions Compared with conventional laryngoscopy, tracheal intubation using the fiberoptic laryngoscope was associated with lower intubation difficulty scale scores and better views of the laryngeal aperture in patients with cervical imnmobilization. However, there were no differences in success rates or number of intubation attempts.

Background: Tracheal intubation is the most reliable way of securing an airway. Pediatric airway management is one of the significant challenges, especially for non-pediatric anesthesiologists. Early airway evaluation for detecting difficult intubation and preventing catastrophic events is necessary before anesthesia, especially in children. Objectives: Therefore, this study was done to compare some valuable adult predictors in children under two years of age. Methods: This prospective descriptive-analytical study was performed on 405 children under two years of age that were referred for elective surgery under general anesthesia with endotracheal intubation in Imam Hossein Hospital, Isfahan. Under sedation in a supine position, we measured items, including age, weight, height, stern omental distance (SMD), mouth opening (MO), neck circumference (NC), acromio-axillo-suprasternal notch index (AASI), and intubation difficulty scale score (IDS). An expert anesthesiologist did laryngoscopy and intubation, and difficult cases were recorded. Results: Our study showed that the frequency of difficult intubation with IDS > 4 was %16, and with IDS > 5 was %3. The variables, including age, weight, height, and SMD, significantly predicted difficult intubation. The cut-off points for age < 6 months, weight < 5/9 kg, height < 61 cm, and SMD < 5/3 cm were obtained, respectively. Other variables, such as MO, AASI, NC, and sex, were unreliable predictors for difficult intubation. Conclusions: We found that IDS > 4, age< 6-month, weight < 5/9 kg, and SMD < 5/3 cm are predictors for difficult intubation. It is helpful for the anesthesiologist to measure these predictions before anesthesia is started to find who has difficult intubation.

OBJECTIVE To compare the effectiveness of mobilization and self-exercises in the management of adhesive capsulitis of shoulder STUDY DESIGN Randomized Control Trial SAMPLE SELECTION 30 patients of adhesive capsulitis of shoulder from physiotherapy department of tertiary care hospitals of Karachi were selected through simple random sampling technique. PROCEDURE Treatment was continued for 5 days per week for the period of 3 weeks followed by assessment. Patients were randomly divided into two equal groups. Group A was treated with midrange mobilization while group B performed self-exercises. Both groups received TENS and hot pack prior to the exercises. Mean ± SD, frequencies and percentages were used for descriptive analysis. ROM via goniometry and pain intensity through VAS was analyzed by paired t-test within the groups and by independent t-test between the groups, using SPSS. P-value of less than 0.05 was considered significant. RESULTS 60% were females (n=18) and 40% were males (n=12) with mean age of 50.17±6.37 years. Significant improvement (p-value <0.05) in pain and shoulder ROM was observed among patients of Group A as compared to Group B. Pain intensity was decreased to 1.67 ± 0.62 in group A, whereas ROMs in these patients were also better than other group.
