Observance of preoperative clear fluid fasting in pediatric anesthesia: oral and written information versus text message information. A before-and-after study.

INTRODUCTION: Prolonged fasting before surgery is common in pediatrics. In the literature, it is responsible for hypotension, irritability and postoperative nausea and vomiting. Despite clear instructions given during the preanesthetic consultation, fasting rules are respected in only 30%-40% of cases. We aimed to evaluate the benefit of sending a text message the day before surgery to improve the parents' observance of fasting rules. METHODS: We conducted a before-and-after study at the University Hospital of Poitiers. From August to October 2018, 172 parents of children under 15 years of age scheduled for all types of surgery were enrolled into two groups according to the period: the control group with parents receiving information on preoperative fasting rules during the preanesthetic consultation several days before surgery, and the text message group, receiving the same information during consultation plus a text message the day before the surgery. RESULTS: There was a difference in observance of clear fluid fasting instructions (between 2 and 3 h before the admission at hospital) in favor of the text message group 33% versus 92% OR 29.2 (10.9-95.2) p < 0.001, and in average fasting time for clear fluids 8.7 h ± 4.8 h vs. 4.3 h ± 2.4 h (p < 0.001). CONCLUSION: Sending of a reminder text message to the parents the day before the surgery resulted in a significant increase in observance of fasting rules in children undergoing scheduled surgery.

A comparison between the flexor hallucis brevis and adductor pollicis muscles in atracurium-induced neuromuscular blockade using acceleromyography: A prospective observational study.

BACKGROUND: Neuromuscular blockade (NMB) monitoring is essential to avoid residual NMB. While the adductor pollicis is the recommended site for monitoring recovery, it is not always accessible. The flexor hallucis brevis could be an interesting alternative. OBJECTIVE: The aim of our study was to compare NMB onset and recovery at both sites. DESIGN: Prospective observational study. SETTING: Operating rooms at the University Hospital of Poitiers, France. PATIENTS: Sixty patients scheduled for surgery under general anaesthesia with neuromuscular blocking agents were enrolled from January 2016 to September 2017. Data from 56 patients were finally analysed. Among these, 11 patients received pharmacological reversal with neostigmine and atropine before emergence from anaesthesia. INTERVENTION: After atracurium injection, NMB onset and recovery at the adductor pollicis and flexor hallucis brevis were monitored simultaneously. MAIN OUTCOME MEASURES: The time to NMB onset, defined as a train-of-four (TOF) count equal to 0, and the times to NMB recovery: TOF = 1, TOF = 4, T4/T1 ratio = 0.75 and T4/T1 ratio more than 0.90. RESULTS: NMB onset was significantly slower at the flexor hallucis brevis with a mean onset time of 4.4 ±â€Š1.5 versus 3.7 ±â€Š1.2 min at adductor pollicis (P = 0.0001). Recovery to TOF = 1 was significantly slower at flexor hallucis brevis. No difference was found for TOF = 4. The full recovery of NMB (T4/T1 > 0.90) was significantly faster at flexor hallucis brevis with a mean time to recovery of 59.5 ±â€Š9.9 versus 64.5 ±â€Š10.7 min at adductor pollicis (P < 0.0001), a difference of 4.9 min between both sites. This difference was not present after pharmacological reversal with a mean time to recovery of 53.0 ±â€Š12.2 min at flexor hallucis brevis versus 54.0 ±â€Š12.4 min at adductor pollicis (P = 0.28). However, NMB onset and recovery did not follow the same pattern in individual patients. CONCLUSION: Flexor hallucis brevis could be an interesting alternative site for NMB monitoring when the adductor pollicis is not accessible. However, in the absence of pharmacological reversal, monitoring at the hallucis brevis muscle should be used with caution for the detection of residual paralysis.

Exerciser for rehabilitation of the Arm (ERA): Development and unique features of a 3D end-effector robot.

Stroke is one of the leading causes of disability worldwide. Consequently, many stroke survivors exhibit difficulties undergoing voluntary movement in their affected upper limb, compromising their functional performance and level of independence. To minimize the negative impact of stroke disabilities, exercises are recognized as a key element in post-stroke rehabilitation. In order to provide the practice of exercises in a uniform and controlled manner as well as increasing the efficiency of therapists' interventions, robotic training has been found, and continues to prove itself, as an innovative intervention for post-stroke rehabilitation. However, the complexity as well as the limited degrees of freedom and workspace of currently commercially available robots can limit their use in clinical settings. Up to now, user-friendly robots covering a sufficiently large workspace for training of the upper limb in its full range of motion are lacking. This paper presents the design and implementation of ERA, an upper-limb 3-DOF force-controlled exerciser robot, which presents a workspace covering the entire range of motion of the upper limb. The ERA robot provides 3D reaching movements in a haptic virtual environment. A description of the hardware and software components of the ERA robot is also presented along with a demonstration of its capabilities in one of the three operational modes that were developed.
