Abstract Background Spinal anesthesia using the midline approach might be technically difficult in geriatric population. We hypothesized that pre-procedural ultrasound (US)-guided paramedian technique and pre-procedural US-guided midline technique would result in a different spinal anesthesia success rate at first attempt when compared with the conventional landmark-guided midline technique in elderly patients. Methods In this prospective, randomized, controlled study, one hundred-eighty consenting patients scheduled for elective surgery were randomized into the conventional surface landmark-guided midline technique (group LM), the pre-procedural US-guided paramedian technique (group UP), or the pre-procedural US-guided midline technique (group UM) with 60 patients in each group. All spinal anesthesia were performed by a novice resident. Results The successful dural puncture rate on first attempt (primary outcome) was higher in groups LM and UM (77 and 73% respectively) than in group UP (42%; P < 0.001). The median number of attempts was lower in groups LM and UM (1 [1] and 1 [1–1.75] respectively) than in group UP (2 [1, 2]; P < 0.001). The median number of passes was lower in groups LM and UM (2 [0.25–3] and 2 [0–4]; respectively) than in group UP (4 [2–7.75]; P < 0.001). The time taken to perform the spinal anesthesia was not different between groups LM and UM (87.24 ± 79.51 s and 116.32 ± 98.12 s, respectively) but shorter than in group UP (154.58 ± 91.51 s; P < 0.001). Conclusions A pre-procedural US scan did not improve the ease of midline and paramedian spinal anesthesia as compared to the conventional landmark midline technique when performed by junior residents in elderly population.

Abstract Background: Previous studies have demonstrated that the common laryngoscopic approach (right-sided) and midline approach are both used for endotracheal intubation by direct laryngoscopy. Although the midline approach is commonly recommended for video laryngoscopy (VL) in the clinic, there is a lack of published evidences to support this practice. This study aimed to evaluate the effects of different video laryngoscopic approaches on intubation. Methods: Two hundred sixty-two patients aged 18 years who underwent elective surgery under general anaesthesia and required endotracheal intubation were included in the present prospective, randomized, controlled study. The participants were randomly and equally allocated to the right approach (Group R) or midline approach (Group M). All the intubations were conducted by experienced anaesthetists using GlideScope video laryngoscopy. The primary outcomes were Cormack-Lehane laryngoscopic views (CLVs) and first-pass success (FPS) rates. The secondary outcomes were the time to glottis exposure, time to tracheal intubation, haemodynamic responses and other adverse events. Comparative analysis was performed between the groups. Results: Finally, 262 patients completed the study, and all the tracheas were successfully intubated. No significant differences were observed in the patient characteristics and airway assessments ( P >0.05). Compared with Group R, Group M had a better CLV ( χ2 =14.706, P =0.001) and shorter times to glottis exposure (8.82±2.04 vs 12.38±1.81; t =14.94; P <0.001) and tracheal intubation (37.19±5.01 vs 45.23±4.81; t =13.25; P <0.001), but no difference was found in the FPS rate (70.2% vs 71.8%; χ2 =0.074; P =0.446) and intubation procedure time (29.86±2.56 vs 30.46±2.97, t =1.75, P =0.081). Between the groups, the rates of hoarseness or sore throat, minor injury, hypoxemia and changes in SBP and HR showed no significant difference ( P >0.05). Conclusion: Although the FPS rate did not differ based on the laryngoscopic approach, the midline approach could provide better glottis exposure and shorter times to glottis exposure and intubation. The midline approach should be recommended for teaching in VL-assisted endotracheal intubation. Trial registration: The study was registered in the Chinese Clinical Trial Registry ( ChiCTR-RNC-1900023252 ).

8549 Background: Timing and frequency of non occlusive (nO) or occlusive (O) CVCrT in cancer patients (pts) remain unclear. In this randomized controlled trial we studied these points and evaluated the efficacy and safety of short-term prophylaxis with A or D in the prevention of CVCrT. Methods: Consecutive cancer pts without contraindications to short-term anticoagulation, scheduled for chemotherapy via CVC, were randomly assigned to receive: A 1 mg/day for 3 days before and 8 days after CVC insertion; D 5,000 IU 2 hours before and daily for 8 days after CVC insertion; no anticoagulant treatment (NT). All pts underwent venography (V) at day 8 and 30 after CVC insertion and then every two months until CVC removal . The primary endpoint was V detected CVCrT, evaluated as nO or O when it was partially or completely occlusive of the vein lumen, respectively. Bleeding episodes were recorded. Proportions were compared using chi-square test together with odds ratio (OR). Results: 450 pts were randomized, 348 of whom (120/150 A, 114/150 D, and 114/150 NT) underwent V (median number of procedures 4, range 2–8). Both A and D reduced the frequency of V detected CVCrT (21.9% A vs 55.3% NT, OR= 4.35 (95% CI 2.43–7.69), p<0.001; 40% D vs 55.3% NT, OR= 1.85 (95% CI 1.10–3.13), p=0.02). A was more effective than D (OR= 2.37 (CI 1.34–4.22), p= 0.003). The frequency of O CVCrT was not different in the 3 groups (0.9% A, 5.0% D, 4.4% NT; p= 0.18). Overall, 5.1% of pts with CVCrT were symptomatic, all presenting O CVCrT (42% of pts with O CVCrT were not symptomatic). Most CVCrTs (95.6%) were observed at day 8 after CVC insertion. No major bleeding or pulmonary embolism occurred. Conclusions: In this study, acenocumarine was more effective than dalteparine in reducing V detected CVCrT. The doses of prophylactic agents used in this study proved to be safe. Symptomatic CVCrT evaluation alone underestimates the actual CVCrT frequency. The first days following CVC insertion are at highest risk for CVCrT. Short term thrombosis prophylaxis appears to be superior to no treatment without the expenses and inconveniences inherent in long-term prophylaxis. No significant financial relationships to disclose.

Abstract Background: Previous studies demonstrated that the common laryngoscopic approach (right-sided) and midline approach are both used for endotracheal intubation by direct laryngoscopy. Although a midline approach is commonly recommended for video laryngoscopy (VL) in clinical, lacking of published evidences to support it. The study aimed to evaluate the effects of different video laryngoscopic approach on intubation. Methods: Two hundred and sixty-two patients aged 18 years who underwent elective surgery in general anesthesia, requiring endotracheal intubation, were included in the prospective, randomized, controlled study. Participants were randomly and equally allocated to right approach (Group R) or midline approach (Group M). All intubations were conducted with GlideScope video laryngoscopy by experienced anaesthetists. The primary outcomes were Cormack-Lehane laryngoscopic views (CLV) and first-pass success (FPS) rate. The secondary outcomes were time to glottis exposure, time to tracheal intubation, hemodynamic response and other adverse events. Comparative analysis was performed between the both groups. Results: All patients ultimately were successfully intubated. No significant differences were observed in patient characteristics and airway assessments (P＞0.05). Compared with Group R, Group M had a better CLV (χ2=14.706, P=0.001) and shorter time to glottis exposure (8.82±2.04 vs 12.38±1.81, t=14.94, P<0.001) and tracheal intubation (37.19±5.01 vs 45.23±4.81, t=13.25, P<0.001), but no difference in FPS rate (70.2% vs 71.8%, χ2=0.074, P=0.446). Between groups, the rates of hoarseness or sore throat, minor injury, hypoxemiaand changes of SBP and HR were noted no significant difference (P＞0.05). Conclusion: Although FPS rate did not differ based upon laryngoscopic approach type; however, the midline approach could provide a better glottis exposure, shorter time to glottis exposure and intubation. The midline approach should be recommended for teaching in VL-assisted endotracheal intubation. Trial registration: The study was registered in Chinese Clinical Trial Registry (ChiCTR-RNC-13003898).

Abstract Background: Adequate shapes for videolaryngoscopes are important for safer, faster, and successful intubation. The aim of this study was to compare two different shapes of stylets, the 60º and J-shape stylets, for intubation with the McGrath MAC®. Methods: In this multicenter, prospective, randomized controlled study, patients undergoing elective surgery under general anesthesia were randomly assigned into the 60º group or the J group. After anesthetic induction, subjects in both groups were intubated with an endotracheal tube bent into a specific shape according to the group allocation. Time to intubation, difficulty of intubation, glottic view grade, use of external manipulation, and number of intubation attempts were recorded. Results: One hundred and eight patients in the J group and 110 patients in the 60º group were enrolled. Time to intubation in the J group [23.1 (20.6-28.0)] was not different from the 60º group [24.8 (20.5-28.3), P = 0.623). There were no differences in difficulty of intubation, glottic view grade, use of external manipulation, and number of intubation attempts between the two groups. Conclusions: Adding extra curvature to the tube to resemble the shape of the blade did not improve the intubation conditions of the McGrath MAC®.

AbstractTranslation of community-based functional training for older adults to reduce frailty is still lacking. We evaluated the effectiveness and implementation of a community-delivered group-based functional power training (FPT) program for frail older adults within their neighborhoods. A two-arm, multicenter assessor-blind stratified randomized controlled trial was conducted at four local senior activity centers in Singapore. Sixty-one community-dwelling older adults with low handgrip strength were randomized to intervention (IG) or control (CG) group. The IG underwent the FPT program (power and balance exercises using simple equipment) delivered by a community service provider. The 12-week program comprised 2 × 60 min sessions/week. CG continued usual activities at the centers. Functional performance, muscle strength, and frailty status were assessed at baseline and 3 months. Program implementation was evaluated using RE-AIM framework. The program was halted due to Coronavirus Disease 2019-related suspension of senior center activities. Results are reported from four centers, which completed the program. IG showed significantly greater improvement in the Short Physical Performance Battery test as compared to CG (p = 0.047). No effects were found for timed up and go test performance, muscle strength, and frailty status. The community program exhibited good reach, effectiveness, adoption, and implementation. Our study demonstrated that FPT was associated with greater improvement in physical function in pre-frail/frail participants as compared to exercise activities offered at local senior activity centers. It is a feasible intervention that can be successfully implemented for frail older adults in their neighborhoods. Trial registration ClinicalTrials.gov, NCT04438876.

Abstract Background TheraTogs promotes proprioceptive sense of a child with cerebral palsy and improves abnormal muscle tone, posture alignment, balance, and gait. Therefore, the aim of this study was to investigate the efficacy of TheraTogs orthotic undergarment on gait pattern in children with dyskinetic cerebral palsy. Thirty children with dyskinetic cerebral palsy were selected for this randomized controlled study. They were randomly assigned to (1) an experimental group that received TheraTogs orthotic undergarment (12 h/day, 3 days/week) plus traditional physical therapy for 3 successive months and (2) a control group that received only traditional physical therapy program for the same time period. Gait parameters were measured at baseline and after 3 months of intervention using Pro-Reflex motion analysis. Results Children in both groups showed significant improvements in the gait parameters (P < 0.05), with significantly greater improvements in the experimental group than in the control group. Conclusions The use of TheraTogs may have a positive effect to improve gait pattern in children with dyskinetic cerebral palsy. Trial registration This trial was registered in the ClinicalTrial.gov PRS (NCT03037697).
