Medical Support for Children's Mass Gatherings

2003

AbstractIntroduction:Medical care must be well-planned for mass gatherings. Events such as fairs, concerts, parades, and rallies cause many people to gather in one place, increasing the chance of injuries and for the development of a disaster. In this study, the level and quality of medical care were evaluated at a mass gathering of approximately 100,000 children. The event was a television-sponsored fun fair.Methods:Every patient contact was documented on printed forms, including data such as the number of patients treated, gender of the patients, presence or absence of a parental escort, time distribution of patient contacts, the diagnoses for the patient contacts, specific therapies appl…

Epidural ropivacaine -- where are the benefits? A prospective, randomized, double-blind trial in patients with retropubic prostatectomy.

2007

Background:  In comparison with bupivacaine, ropivacaine exhibits comparable anaesthetic effects but with less motor impairment and systemic toxicity. However, the analgesic potency may differ. For example, ropivacaine during obstetric epidural analgesia provides an approximately 40% lower analgesic potency than bupivacaine. Equal visual analogue pain scores require significantly higher dosages of ropivacaine, and general statements about a favourable benefit–risk profile relative to that of bupivacaine may therefore have limited clinical impact. We addressed this topic in a male pain model by evaluating the analgesic efficacy of epidural ropivacaine 0.2% vs. bupivacaine 0.125% after retrop…

Evaluation of the novel, single-use, flexible aScope® for tracheal intubation in the simulated difficult airway and first clinical experiences

2010

Flexible fibreoptic intubation is widely accepted as an important modality for the management of patients with difficult airways. We compared the aScope, a novel, single-use, flexible video-endoscope designed to aid tracheal intubation, with a standard flexible intubating fibrescope, by examining the performance of 21 anaesthetists during an easy and difficult intubation simulation in a manikin. Intubation success, time for intubation, and rating of the devices (using a scale from 1, excellent to 6, fail) were documented. Intubation times were similar for both flexible 'scopes in the scenarios (p = 0.59). Successful intubation rates were higher for the standard intubating fibrescope (17/21,…

Premature termination of epidural analgesia—A prospective analysis to improve quality

2009

Summary Background and objective Epidural analgesia (EA) is a gold-standard in post-operative pain control. Therefore, modern treatment concepts targeting early patient recovery regularly implement EA. Due to its increasing impact, EA should meet high quality standards in respect to application and maintenance. Though, daily practice often reveals EA-related problems, our investigation aimed to improve EA quality by assessing incidence and reasons of undeliberate, premature termination of post-operative EA. Methods In the first step all patients with post-operative EA were retrospectively studied covering a 6-month period (group 1). We analysed incidences and reasons of undeliberate termina…

A comparison of the Enk Fiberoptic Atomizer Set(™) with boluses of topical anaesthesia for awake fibreoptic intubation.

2016

We compared the Enk Fiberoptic Atomizer Set(™) with boluses of topical anaesthesia administered via the working channel during awake fibreoptic tracheal intubation in 96 patients undergoing elective surgery. Patients who received topical anaesthesia via the atomiser, compared with boluses via the fibreoptic scope, reported a better median (IQR [range]) level of comfort: 1 (1-3 [1-10]) vs. 4 (2-6 [1-10]), p < 0.0001; experienced a reduced total number of coughs: 6 (3-10 [0-34]) vs. 11 (6-13 [0-25]), p = 0.0055; and fewer distinct coughing episodes: 7% vs. 27% respectively, p = 0.0133. The atomiser technique was quicker: 5 (3-6 [2-12]) min vs. 6 (5-7 [2-15]) min, p = 0.0009; and required less…

LMA Supreme™ and Ambu® AuraGain™ in anesthetized adult patients: a prospective observational study

2017

BACKGROUND Second-generation laryngeal masks with gastric access are increasingly used in daily practice and expand the indications for laryngeal masks in the OR. Only limited data exist comparing different types of laryngeal masks. We investigated the second-generation laryngeal masks LMA Supreme™ and Ambu® AuraGain™ in a clinical setting. We hypothesized that the two devices would be comparable in terms of success rate and airway complications. METHODS After approval from the local ethics committee, data were collected in a prospective trial. Endpoints were success rate, time to insertion and airway morbidity. Anesthesiologists used either the Supreme (Teleflex Medical GmbH) or Gain (Ambu…

Nasotracheal intubation: look before you leap

2005

Nasotracheal intubation is frequently used for airway management during maxillofacial surgery. Complications such as haemorrhage occur more frequently with this route of intubation than with the orotracheal route. This case report describes a male patient aged 51 yr who developed severe epistaxis after the tube had passed the nares. As an additional complication laryngoscopy and endotracheal intubation failed because of difficult airway (Cormack-Lehane grade 4). Attempts using an intubating laryngeal mask airway and a Bonfils intubating fibrescope did not succeed. The airway was finally managed by cricothyroidotomy. A modified sequence of nasotracheal intubation is proposed to avoid similar…

Management of incomplete regional anaesthesia in Germany: results of a nation-wide survey.

2007

Background:  Regional anaesthesia (RA) provides well-defined benefits with known attendant risks. However, incomplete blockade may introduce unanticipated risks depending on the compensatory measures employed. Until now, no data were available characterizing the pattern of response of German anaesthesiologists in this situation. This study analyses interventions in response to incomplete RA in a nation-wide setting. Methods:  A questionnaire was sent to every German anaesthesia department (n= 1381). Questions focused on interventions coping with an incomplete RA and differentiated between a pre- and a peri-surgical setting and measures to face pain outside the surgical field. If systemic su…

The Orogastric Tube Guide® as a novel strategy for gastric tube insertion: a prospective, randomized controlled clinical trial

2020

BACKGROUND Gastric tube insertion, either orally or nasally, is daily practice in anesthesia and intensive care. "Blind" insertion represents the common conventional method and is associated with low first-pass success and frequent complications. This trial aimed to evaluate the novel gastric tube guide as a rigid conduit in regard to insertion success rate, time required and associated complications versus the conventional "blind" insertion method. We hypothesized that the insertion success rate is higher using the Orogastric tube guide. METHODS This trial was approved by ethics committee prior to patient recruitment. In a randomized order, anesthetists performed oral insertion of a gastri…

Two-rescuer CPR results in hyperventilation in the ventilating rescuer.

2005

The "Guidelines 2000 for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care--International Consensus on Science" recommend a tidal ventilation volume of 10 ml/kg body-weight without the use of supplemental oxygen during two-rescuer adult cardiopulmonary resuscitation (CPR). This relates to a ventilation volume of about 6.4 l/min. Additionally, the first aid provider ventilating the victim will breathe for him/herself during the external chest compression period adding another 3.2 l/min of ventilation. Finally, a deep breath is recommended before each ventilation to increase the end-expiratory oxygen concentration of the air exhaled. To investigate the effects of these recommend…

Red blood cell transfusion in perioperative pediatric anesthesia: a survey of current practice in Germany.

The two-lumen design of the EzT enables it to be used as an endotracheal tube or as a supraglottic emergency airway.To report the preliminary experiences with the EzT airway device in prehospital and in-hospital emergency airway management procedures.All airway management procedures involving the EzT were recorded for a period of 18 months.The EzT was successfully used to intubate 15 patients with unanticipated airway difficulties during either anesthesia induction or prehospital airway management. In all patients, the Ez…

Endotracheal intubation using the C-MAC® video laryngoscope or the Macintosh laryngoscope: A prospective, comparative study in the ICU

2012

Introduction Endotracheal intubation in the ICU is a challenging procedure and is frequently associated with life-threatening complications. The aim of this study was to investigate the effect of the C-MAC® video laryngoscope on laryngeal view and intubation success compared with direct laryngoscopy. Methods In a single-center, prospective, comparative before-after study in an anesthetist-lead surgical ICU of a tertiary university hospital, predictors of potentially difficult tracheal intubation, number of intubation attempts, success rate and glottic view were evaluated during a 2-year study period (first year, Macintosh laryngoscopy (ML); second year, C-MAC®). Results A total of 274 criti…

Airway management techniques in a restricted-access situation: a manikin study

2016

Background Access to patients can be restricted in emergency situations. A variety of techniques and devices are available for use in patients who require oxygenation in a restricted-access situation. Objectives The aim of this study was to investigate whether there is one ventilation technique that is superior to others. Materials and methods Fifty-four emergency medical services providers including emergency medical technicians, paramedics and physicians were asked to use a bag-valve mask (BVM), a laryngeal mask airway (LMA), and a laryngeal tube (LT) to ventilate a full-scale manikin sitting upright in the driver's seat of a motor vehicle. Access to the manikin was gained through the sid…

The novel video-assisted intubating laryngeal mask Totaltrack compared to the intubating laryngeal mask Fastrach - a controlled randomized manikin st…

2017

BACKGROUND The novel Totaltrack combines a supraglottic airway device with video laryngoscopic tracheal intubation. The intubation laryngeal mask Fastrach is an established device without visual control of intubation. We hypothesized that supraglottic ventilation success with Totaltrack would be similar to Fastrach, but intubation would be performed faster due to visual control of the procedure. METHODS Fifty-five anaesthesiologists were randomized into one of two study arms: Fastrach Totaltrack. After a standardized introduction, six consecutive attempts of supraglottic ventilation and intubation attempts with each of one of the devices were performed on an airway manikin. The combined pri…

Comparison of two different techniques of fibreoptic intubation

2009

BACKGROUND AND OBJECTIVE The application of analgesics and sedatives during fibreoptic intubation (FOI) may result in a transient decrease in arterial oxygen saturation.This study evaluates two different techniques of FOI and respective effects on procedural duration, arterial oxygen saturation, and coughing by the patient. METHODS Thirty-four patients received a standardized conscious sedation with fentanyl (1.5 microg kg(-1)) and midazolam (12.5 microg kg(-1)).All patients were randomly allocated to one of the following techniques: the 'vaporization' (VAP) technique included four applications of 2 ml lidocaine 2% administered through the working channel of the fibrescope supplying an oxyg…

Evaluation of the McGrath® Series 5 videolaryngoscope after failed direct laryngoscopy*

2010

Summary Unanticipated difficulties during tracheal intubation and failure to intubate are among the leading causes of anaesthesia-related morbidity and mortality. Using the technique of video laryngoscopy, the alignment of the oral and pharyngeal axes to facilitate tracheal intubation is unnecessary. In this study we evaluated the McGrath® Series 5 videolaryngoscope for tracheal intubation in 61 patients who exhibited Cormack and Lehane grade 3 or 4 laryngoscopies with a Macintosh laryngoscope. Using the McGrath resulted in an improved glottic view, compared to Macintosh laryngoscope. Laryngoscopy was improved by one grade in 10%, by two grades in 80% and by three grades in 10% of cases (p …

Performance of the C-MAC video laryngoscope in patients after a limited glottic view using Macintosh laryngoscopy

2011

We applied the C-MAC videolaryngoscope in 52 consecutive patients who were found to have an unexpected Cormack and Lehane grade-3 (n = 49) and grade-4 (n = 3) laryngeal view with the Macintosh laryngoscope. The glottic view improved in 49 (94%) patients using the C-MAC. Tracheal intubation was successful in 49 of 52 patients (94%). In one patient, tracheal intubation failed using the C-MAC despite the presence of a Cormack and Lehane grade-2. These results suggest that the C-MAC videolaryngoscope has a role as a rescue device in cases of an initially difficult laryngeal view.

Intraoperative tramadol reduces shivering but not pain after remifentanil–isoflurane general anaesthesia. A placebo-controlled, double-blind trial

2008

Background and objective Postoperative shivering and pain are frequent problems in patients recovering from anaesthesia with particularly high incidences being observed after remifentanil–isoflurane-based general anaesthesia. The opioid tramadol is generally effective in preventing shivering and treating pain, but its effects are not characterized after remifentanil-based general anaesthesia. This randomized, placebo-controlled, double-blind study evaluated the effects of intraoperative intravenous tramadol on postoperative shivering and pain after remifentanil-based general anaesthesia. Methods After Ethics Committee approval, 60 patients scheduled for lumbar disc surgery were included. Su…
