Development and evaluation of an algorithm for peripheral venous catheter placement (ALCOV): protocol for a quasi-experimental study.

Introduction: Multiple punctures during peripheral venous catheter (PVC) placement increase the risk of complications. Scoring for adult difficult intravenous access (A-DIVA Scale) exists but has never been assessed in the framework of a care algorithm (scoring associated with a new decision-making tree for puncture conditions, the A-DIVA Tree). We seek to implement an catheter placement algorithm to decrease the mean number of punctures per patient.

Influential factors on the echogenicity of peripheral venous catheters: Insights from an experimental phantom study.

Introduction: Ultrasound-guided placement of peripheral venous catheters requires appropriate equipment. Among the devices used, peripheral venous catheters have different structure and properties. This study aimed to define the impact of these different factors on the echogenicity of peripheral venous catheters.

Quality of Preanesthesia Teleconsultation: The TELECAM Randomized Controlled Trial.

Preanesthesia teleconsultation helps reduce availability constraints as well as direct and indirect expenses. The TELECAM trial was performed to assess the quality of preanesthesia teleconsultation in terms of clinical parameters evaluation, feasibility, patient satisfaction and preoperative anxiety, and anesthesiologist satisfaction. TELECAM was an investigator-initiated, prospective, single-center, randomized, controlled, parallel group, evaluator-blinded, open-label study.

Benefits of simulation for ultrasound-guided midline placement training: MC-in-Sim pilot study.

Introduction: Ultrasound-guided placement of Midlines catheters (MCs) is a standard procedure with many benefits for patients. Even if there are some guidelines worldwide, this invasive technique is still taught at the patient's bed and relies on mentoring in many care centers. The performance of this care by novice practitioners raises ethical and quality of care issues mainly because of its risk of complications.

Arterial Cannulation Simulation Training in Novice Ultrasound Users.

Background: Arterial cannulation is an important procedure for hemodynamic monitoring and blood sampling. Traditional radial artery cannulation is performed by using anatomical knowledge and pulse palpation as a guide. Arterial cannulation using ultrasound (US) requires specific training, especially for new US users.

Comparative study of the reliability of ultrasound to confirm the position of endotracheal tube with cuff inflated with saline versus air.

To compare the reliability of transtracheal ultrasound to confirm the endotracheal tube position with saline versus air inflated cuff. This was a prospective randomized cadaveric study. Four techniques were randomized: endotracheal tube in the trachea with air or saline inflated cuff, and endotracheal tube in the esophagus with air or saline inflated cuff.

Ultrasound assessment of gastric contents prior to placental delivery: A prospective multicentre cohort study.

Background: There is ongoing debate regarding the optimal general anaesthetic technique for manual removal of the placenta after vaginal delivery. Using ultrasound examination of the gastric antrum, this study aimed to assess the change in gastric contents during vaginal delivery and to determine the prevalence of stomach at risk for pulmonary aspiration in the immediate postpartum period before placental delivery.

Methods: In this prospective multicentre cohort study, antral ultrasonography was performed at full cervical dilatation within the thirty minutes preceding the beginning of expulsive efforts and after vaginal birth, before placental delivery.

Effects of pupillary reflex dilation-guided opioid administration on remifentanil and morphine consumption during laparoscopic surgery: A randomised controlled trial.

Background: Analysis of pupillary reflex dilation (PRD) assesses the balance of nociception--antinociception. Laparoscopic surgery induces haemodynamic variations that are misleading. During laparoscopy, PRD guidance helps differentiate haemodynamic changes because of excess nociception from secondary changes related to the reflex release of endocrine factors.

Training novice in ultrasound-guided venipuncture: A randomized controlled trial comparing out-of-plane needle-guided versus free-hand ultrasound techniques on a simulator.

Background: Peripheral intravenous access is a common medical procedure, however, it can be difficult to perform in some patients. Success rates have proved greater with ultrasound guidance. Peripheral intravenous access using ultrasound requires specific training, especially for new ultrasound users.

A national healthcare response to intensive care bed requirements during the COVID-19 outbreak in France.

Background: Whereas 5415 Intensive Care Unit (ICU) beds were initially available, 7148 COVID-19 patients were hospitalised in the ICU at the peak of the outbreak. The present study reports how the French Health Care system created temporary ICU beds to avoid being overwhelmed.

Methods: All French ICUs were contacted for answering a questionnaire focusing on the available beds and health care providers before and during the outbreak.

Factors Determining the Choice of Spinal Versus General Anesthesia in Patients Undergoing Ambulatory Surgery: Results of a Multicenter Observational Study.

Introduction: Available short-acting intrathecal anesthetic agents (chloroprocaine and prilocaine) offer an alternative to general anesthesia for short-duration surgical procedures, especially ambulatory surgeries. Factors determining the choice of anesthesia for short-duration procedures have not been previously identified.

Methods: This observational, prospective, multicenter, cohort study was conducted between July 2015 and July 2016, in 33 private or public hospitals performing ambulatory surgery.

Impact of Chloroprocaine on the Eligibility for Hospital Discharge in Patients Requiring Ambulatory Surgery Under Spinal Anesthesia: An Observational Multicenter Prospective Study.

Introduction: This observational study was designed to assess the use of spinal anesthesia with chloroprocaine in the context of ambulatory surgery.

Methods: A prospective, multicenter, observational study was carried out among 33 private or public centers between May 2014 and January 2015 and adult patients, scheduled for a short ambulatory surgery under spinal anesthesia with chloroprocaine. The primary outcomes were anesthetic effectiveness, defined as performance of the whole surgical procedure without any additional anesthetic agent, and the time to achieve eligibility for hospital discharge.

Postoperative Clinical Monitoring After Morphine Administration: A Retrospective Multicenter Practice Survey.

Background: The objective of this survey was to describe the clinical monitoring practically used after intravenous, subcutaneous or neuraxial (epidural or intrathecal) administration of morphine.

Methods: It was a descriptive, retrospective, multicenter (10 hospitals) survey based on the medical charts' analysis, which evaluated the postoperative clinical monitoring after morphine administration.

Results: Morphine was delivered intravenously (69%), intrathecally (19%), epidurally (10%) and/or subcutaneously (12%).

Reliability of cuff pressure gauges.

Cuff pressure gauges are the only recommended instrument to perform controls on endotracheal tube cuff pressure during anesthesia. No calibration is mandatory for these devices. The aim of this study was to describe the level of conformity of various cuff pressure gauges.

Ultrasound-Guided Selective Versus Conventional Block of the Medial Brachial Cutaneous and the Intercostobrachial Nerves: A Randomized Clinical Trial.

Background And Objectives: For superficial surgery of anteromedial and posteromedial surfaces of the upper arm, the medial brachial cutaneous nerve (MBCN) and the intercostobrachial nerve (ICBN) must be selectively blocked, in addition to an axillary brachial plexus block. We compared efficacy of ultrasound-guided (USG) versus conventional block of the MBCN and the ICBN.

Methods: Eighty-four patients, undergoing upper limb surgery, were randomized to receive either USG (n = 42) or conventional (n = 42) block of the MBCN and the ICBN with 1% mepivacaine.

Guidelines on smoking management during the perioperative period.

Smoking is a public health problem of particular importance during the perioperative period, since it exposes patients scheduled for surgery to risk increases of 20% in hospital mortality and 40% in major postoperative complications. In addition, current smoking increases almost all specific surgical complications. The perioperative period offers a genuine opportunity for smoking cessation.
