Objective: To assess if a color scale in the endotracheal tube (ETT) helps operators to correctly select the size and depth of placement of the ETT and decrease the time required, compared with the usual numeric ETT scale, in a mannequin model. Design/Methods: The study was conducted in 8 centers. Each size of the ETT was identified with different color by size. All experimental ETT had two painted zones: the mouthpiece and an area of 1 cm marked with the same color (to identify where the ETT should be taped above the lip). The operators were trained as part of the protocol using a video. Four clinical scenarios requiring endotracheal intubation were designed and randomly assigned. Each operator had to select the size and depth of ETT based on the BW, and then had to perform 4 intubation procedures. Results: 108 operators performed 432 intubations. No difference were found in the correct placement and selection of the ETT. Median time (in seconds) required for intubation using numeric vs. experimental tube was: for ETT Ø 2.5, 11.5 vs. 8 (p<0.001), ETTØ3,12 vs. 10 (p<0.001), ETT Ø 3.5, 15.5 vs.12 (p 0.003), ETT Ø4 12 vs.11 (p 0.019). Conclusions: No significant difference was observed in the selection and correct placement of the ETT. However, the intubation time was significantly shorter using the experimental ETT. This device could improve the effectiveness of intubation by reducing the time needed to properly place the ETT at mid trachea.

Abstract Background The results of studies on changes in intracranial pressure in patients undergoing laparoscopic surgery are inconsistent. Meanwhile, previous neurosurgery studies have suggested that propofol and sevoflurane have inconsistent effects on cerebral blood flow and cerebrovascular self-regulation. The purpose of this study is to compare changes in the optic nerve sheath diameter in patients undergoing laparoscopic gynecological surgery under anesthetic maintenance with propofol versus sevoflurane. Methods This study included 110 patients undergoing laparoscopic gynecological surgery with an estimated operative time of more than 2 hours under general anesthesia. The study was a randomized controlled study. The optic nerve sheath diameter（ONSD）at various time points was measured by ultrasound, including when the patients entered the operating room (Tawake), after successful anesthesia induction and endotracheal intubation (Tinduction), when the body position was adjusted to the Trendelenburg position and the CO2 pneumoperitoneum pressure reached 14 mmHg, which was recorded as T0. Then, measurements were conducted every 15 minutes for the first 1 hour and then once every hour until the end of the surgery（T15,T30,T45 ,T1h ,T2h…）, after the end of surgery and the tracheal tube was removed (Tend), and before the patients were transferred to the ward (Tpacu).Results A significant difference in optic nerve sheath diameter was found between two groups at T15, T30, T45 (4.64±0.48mm and 4.50±0.29mm, respectively, p=0.031;4.77±0.45mm and 4.62±0.28mm, respectively, p=0.036;4.84±0.46mm and 4.65±0.30mm, respectively, p=0.012), while there was no significant difference at Tawake and other time points. Conclusion During laparoscopic gynecological surgery lasting more than 2 hours, the optic nerve sheath diameter was slightly larger in the propofol group than that in the sevoflurane group in the first 45 minutes. No significant difference was observed between the two groups 1 hour after surgery. Trial registration clinicaltrials.gov，NCT03498235.

Background: Direct laryngoscopy and endotracheal intubation frequently induce cardiovascular stress response characterised by hypertension and tachycardia due to reflex sympathetic stimulation. Considering the clinical significance of these changes stress attenuation is needed to blunt these responses. β- blockers are used to reduce the unwanted hemodynamic responses. Esmolol is ultra-short acting cardio selective β blocker. Labetalol is useful in not only attenuating the response to laryngoscopy and intubation but also in preventing perioperative cardiovascular events. Present study compared the efficacy of esmolol and labetalol for attenuation of sympathomimetic response to laryngoscopy and intubation.Methods: It was a prospective, randomized, controlled study carried out in 75 adult patients with ASA 1 and ASA 2 posted for elective surgeries. Patients were allocated randomly into Group-1 (esmolol) and Group-2 (labetalol) and Group-3 (placebo) of 25 patients each. Inj. esmolol (1mg/kg) or Inj. labetalol (0.4 mg/kg) or placebo (0.9NS) dissolved up to 5 ml in distilled water was injected intravenously 5 minutes prior to intubation. All patients premeditated with Inj. glycopyrrolate (4µg/kg). Patient were then induced with Inj. propofol (2mg/kg), Inj. scoline (2mg/kg) given followed by laryngoscopy and intubation. Haemodynamic readings were noted at T0 (baseline before injecting the drug), T1 (1 minute after injecting the drug), T2 (after intubation), T3 (2 minutes after intubation), T4 (4 minutes after intubation), T5 (6 minutes after intubation), T6 (8 minutes after injection), T7 (10 minutes after injection).Results: Gr-1, Gr-2 and Gr-3, when compared with each other for systolic BP, diastolic BP, mean BP, and HR, showed a statistically significant difference at different intervals.Conclusions: Both the drugs are found to be effective in attenuation of hemodynamic reflex without any side effects. Further studies are recommended to substantiate the findings in present study.

Objectives (1) To conduct an adequately powered randomized controlled trial investigating the safety and efficacy of mitomycin C–enhanced revision endoscopic dacryocystorhinostomy (DCR) and (2) to analyze causes of failure after primary endoscopic DCR. Study Design A randomized controlled study. Setting General hospital. Subjects and Methods Seventy-six revision endoscopic DCRs were randomized into 2 groups: endoscopic DCR with mitomycin (group I), where 0.5 mg/mL mitomycin C was applied for 10 minutes, and endoscopic DCR without mitomycin (group II). Follow-up settings were done to document the patient’s subjective improvement, to judge ostium patency on irrigation, and to record any complications. Results Causes of failure in the original 92 patients included canalicular obstruction (14%), small misplaced bony window (43%), very small nasolacrimal stoma due to development of synechia (23%), and complete closure of nasolacrimal stoma with tough fibrous tissue (63%). There was no significant difference between the 2 groups in subjective and objective success rates and adverse events. Group I demonstrated a significantly longer operative time and a significantly lower number of debridement sessions (mean of 1.2 vs 1.9). Conclusions Recurrent nasolacrimal duct obstruction after primary endoscopic DCR is mainly due to reclosure of the nasolacrimal stoma with synechia and fashioning of the small misplaced bony window. Mitomycin C does not increase the success rate of revision endoscopic DCR. It is a safe procedure and may be of value only in patients inaccessible to strict follow-up because it induces a better healing profile in terms of mucosal recovery, wound healing, and less need for debridement sessions.

Background.Dexamethasone is sometimes used as a coanalgesic because of its anti-inflammatory properties.Objective. To evaluate opioid use, postoperative pain intensity, and side effects after a single dose of dexamethasone in patients undergoing arthroscopic knee surgery.Methods. In this randomized controlled study patients were randomized to receive either 10 mg of intravenous dexamethasone (DM group) or 0.9% normal saline (NS group) during the intraoperative period. Primary outcomes were pain intensity and total morphine and codeine use after surgery.Results. Seventy-eight patients were included in the study. The DM group showed statistically significant higher pain intensity at the fourth postoperative hour (DM: 3.96/10, standard deviation [SD] 0.54; NS: 2.46/10, SD 0.45;p=0.036). No statistically significant difference in total opioid use (morphine plus codeine) was identified with 15.9 (SD 1.97) codeine tablets used in DM group and 20 (SD 2.14) in NS group (p=0.25).Discussion. Pain intensity tended to decrease in both groups suggesting morphine as the main source of analgesia.Conclusions. Intravenous dexamethasone during the intraoperative period has no clinical impact on postoperative pain intensity during the first 48 h after arthroscopic knee surgery. This trial is registered withR000020892.

Purpose: The purpose of this study was to assess the effectiveness of periarticular multidrug infiltration (PMDI) and compare it with that of epidural catheter use. Methods: Fifty-eight patients (58 joints) who underwent total knee arthroplasty were included in this single-center, prospective, parallel, randomized, controlled trial. Preoperatively, patients were randomly categorized into the PMDI and epidural catheter groups. We evaluated postoperative pain (visual analog scale (VAS) and narcotic consumption), functional outcomes (range of motion (ROM) of knee flexion, the day patients could perform the straight-leg raising (SLR) test, and day of starting cane use), and laboratory data (white blood cell (WBC) and C-reactive protein (CRP)). Results: There was no significant difference in the VAS score, ROM of knee flexion, the day patients could do SLR, and the day of starting cane use between the PMDI and epidural catheter groups. However, the PMDI group could perform SLR on a postoperative day (POD) 1 ( p < 0.05). WBC level on POD 1 was significantly higher in the PMDI group ( p < 0.05), whereas the CRP levels on POD 1 ( p < 0.01), 3 ( p < 0.01), and 5 ( p < 0.01) were significantly lower in the PMDI group than in the epidural catheter group. The frequency of side effects was not significantly different between the groups. Conclusion: PMDI was as effective as epidural catheter use for pain control. A higher percentage of patients who underwent PMDI could perform SLR on POD 1; therefore, the functional recovery was earlier in the PMDI group than in the epidural catheter group. PMDI may suppress inflammation in the whole body because of steroids.

Introduction: Point of care ultrasound has been reported to improve diagnosis in non-traumatic hypotensive ED patients. We compared diagnostic performance of physicians with and without PoCUS in undifferentiated hypotensive patients as part of an international prospective randomized controlled study. The primary outcome was diagnostic performance of PoCUS for cardiogenic vs. non-cardiogenic shock. Methods: SHoC-ED recruited hypotensive patients (SBP &lt; 100 mmHg or shock index &gt; 1) in 6 centres in Canada and South Africa. We describe previously unreported secondary outcomes relating to diagnostic accuracy. Patients were randomized to standard clinical assessment (No PoCUS) or PoCUS groups. PoCUS-trained physicians performed scans after initial assessment. Demographics, clinical details and findings were collected prospectively. Initial and secondary diagnoses including shock category were recorded at 0 and 60 minutes. Final diagnosis was determined by independent blinded chart review. Standard statistical tests were employed. Sample size was powered at 0.80 (α:0.05) for a moderate difference. Results: 273 patients were enrolled with follow-up for primary outcome completed for 270. Baseline demographics and perceived category of shock were similar between groups. 11% of patients were determined to have cardiogenic shock. PoCUS had a sensitivity of 80.0% (95% CI 54.8 to 93.0%), specificity 95.5% (90.0 to 98.1%), LR+ve 17.9 (7.34 to 43.8), LR-ve 0.21 (0.08 to 0.58), Diagnostic OR 85.6 (18.2 to 403.6) and accuracy 93.7% (88.0 to 97.2%) for cardiogenic shock. Standard assessment without PoCUS had a sensitivity of 91.7% (64.6 to 98.5%), specificity 93.8% (87.8 to 97.0%), LR+ve 14.8 (7.1 to 30.9), LR- of 0.09 (0.01 to 0.58), Diagnostic OR 166.6 (18.7 to 1481) and accuracy of 93.6% (87.8 to 97.2%). There was no significant difference in sensitivity (-11.7% (-37.8 to 18.3%)) or specificity (1.73% (-4.67 to 8.29%)). Diagnostic performance was also similar between other shock subcategories. Conclusion: As reported in other studies, PoCUS based assessment performed well diagnostically in undifferentiated hypotensive patients, especially as a rule-in test. However performance was similar to standard (non-PoCUS) assessment, which was excellent in this study.

Patients suffering from any class of the Clinical, Etiological, Anatomical, Pathophysiological (CEAP) classification of chronic venous disease (CVD) may be symptomatic (C0s-C6s). Leg heaviness, discomfort, itching, cramps, pain, paresthesia, and edema (C3) are the most frequent manifestations of CVD and a major reason for medical consultation. Daflon 500 mg (micronized purified flavonoid fraction [MPFF]) is an effective treatment for symptoms and edema in CVD as demonstrated in several randomized controlled studies. A 2-month, double-blind study in 40 patients established the superiority of Daflon 500 mg over placebo with regard to symptoms and objective signs. This was confirmed in another double-blind, placebo-controlled trial (2 months’ treatment, 160 patients), and in the Reflux assEssment and quaLity of lIfe improvEment with micronized Flavonoids (RELIEF) study. The latter included 5,052 patients in 23 countries, using a visual analog scale for evaluating pain, leg heaviness, cramps, and a sensation of swelling. All symptoms showed significant and progressive improvement. The quality-of-life results (scores on the ChronIc Venous Insufficiency quality of life Questionnaire [CIVIQ]) paralleled those of symptoms. The decrease in the ankle and calf circumferences was significantly greater (p<0.001) in the group of patients treated with Daflon 500 mg in two studies, and correlated well with the improvement in the sensation of swelling (p<0.001). This was confirmed with more sophisticated measurement techniques as in the RELIEF study or in a trial assessing edema with an optoelectronic volumeter in 20 patients. A further double-blind, randomized, controlled study established a statistically significant difference in favor of Daflon 500 mg in comparison with diosmin, both on symptoms and edema. The therapeutic efficacy of Daflon 500 mg on CVD symptoms and edema has been demonstrated in double-blind, randomized, controlled studies. Further studies using a new approach may define the most precise and validated methodology for application in future research in phlebology.

Abstract Background Capsule endoscopy (CE) is frequently hindered by intra-luminal debris. Our aim was to determine whether a combination bowel preparation would improve small-bowel visualization, diagnostic yield, and the completion rate of CE. Methods Single-blind, prospective randomized–controlled study of outpatients scheduled for CE. Bowel-preparation subjects ingested 2 L of polyethylene glycol solution the night prior to CE, 5 mL simethicone and 5 mg metoclopramide 20 minutes prior to CE and laid in the right lateral position 30 minutes after swallowing CE. Controls had no solid food after 7 p.m. the night prior to CE and no liquids 4 hours prior to CE. Participants completed a satisfaction survey. Capsule readers completed a small-bowel-visualization assessment. Results Fifty patients were prospectively enrolled (56% female) with a median age of 54.4 years and 44 completed the study (23 patients in the control group and 21 in the preparation group). There was no significant difference between groups on quartile-based small-bowel visualization (all P &gt; 0.05). There was no significant difference between groups in diagnostic yield (P = 0.69), mean gastric (P = 0.10) or small-bowel transit time (P = 0.89). The small-bowel completion rate was significantly higher in the preparation group (100% vs 78%; P = 0.02). Bowel-preparation subjects reported significantly more discomfort than controls (62% vs 17%; P = 0.01). Conclusions Combined bowel preparation did not improve small-bowel visualization but did significantly increase patient discomfort. The CE completion rate improved in the preparation group but the diagnostic yield was unaffected. Based on our findings, a bowel preparation prior to CE does not appear to improve CE performance and results in decreased patient satisfaction (ClinicalTrials.gov, No. NCT01243736).

The Impact

Purpose The aim of the study was to determine the impact of telephone follow-up calls on satisfaction in oncology patients after hospital discharge. Method A randomized controlled study, in which patients were randomized into two groups: The experimental group with the telephone follow-up (TFU) calls (intervention) and the control group (no intervention). The telephone follow-up call was conducted within 72 h after discharge. During the call, patients were asked about their medications, namely, whether they received them, understood how to take them, and whether they developed any medication-related adverse effect. Both groups were contacted by phone two weeks later to assess their satisfaction with the discharge medication instructions and the provided pharmaceutical services, using the 5-point Likert scale. In addition, hospital records were reviewed for emergency room visits and hospital readmissions within 30 days after discharge. Results There was no difference in the percentage of patients who reported being very satisfied between both the intervention and the control groups (45% intervention vs. 48% control, P = 0.68). The mean time of the intervention phone call was 3 ± 1.7 (SD) min. During the telephone follow-up call, medication-related problems were identified in 20% of the patients. There was no significant difference in emergency room visits and hospital readmissions in the intervention group vs. control (44% vs. 53%, P = 0.123) and (37% vs. 43%, P = 0.317), respectively. Conclusion Telephone follow-up calls conducted by a pharmacist to discharged oncology patients did not improve patients' satisfaction, emergency room visits or hospital readmissions; however, they helped to identify medication-related adverse effects in the oncology patients.

This study aimed to determine the effects of a school-based multi-component intervention on accelerometer- measured physical activity (PA) and sedentary behavior (SB) in schoolchildren overweight. This is a randomized controlled study with overweight schoolchildren, allocated to experimental group (EG; n = 13; 7.6 ± 0.8 years; 42.9% boys) and control group (CG; n = 17; 8.2 ± 0.9 years; 26.7% boys). The EG was submitted to a 10-week school-based intervention, comprised of PA and psychological sessions (behavioral therapy), and nutritional guidance. The CG followed the daily routine of life. The time of PA and SB were measured using accelerometers used for seven days. To compare mean SB, moderate to vigorous physical activity (MVPA) and total physical activity (TPA), generalized estimation equations (GEE) were used. It was observed that the average time in MVPA and TPA increased significantly in EG at the weekend (+ 40.9 min / day, p < 0.001; and + 51.6 min/day, p = 0.035, respectively) and at full week (+ 62.9 min/day, p < 0.001; and + 225.0 9 min/day, p = 0.038, respectively). There was no significant difference in time spent in SB after the intervention in both groups. Thus, it was concluded that the proposed school-based multicomponent intervention was effective in increasing levels of MVPA and TPA in overweight schoolchildren. This finding can optimize future interventions to promote a healthy lifestyle for schoolchildren in the school environment.
