Laryngeal Mask Airway for neonatal resuscitation in a developing country: evaluation of an educational intervention. Neonatal LMA: an educational intervention in DRC.

ABSTRACT: Studies carried out in developing countries have indicated that training courses in newborn resuscitation are efficacious in teaching local birth attendants how to properly utilize simple resuscitation devices. The aim of this study was to assess the knowledge and expertise gained by physicians and midwifes who participated in a Neonatal Resuscitation Course and workshop organized in a Third World Country on the use of Laryngeal Mask Airway (LMA).A 28-item questionnaire, derived from the standard test contained in the American Heart Association and the American Academy of Pediatrics Neonatal Resuscitation Manual, was administered to 21 physicians and 7 midwifes before and after a course, which included a practical, hands-on workshop focusing on LMA positioning and bag-ventilation in a neonatal manikin.The knowledge gained by the physicians was superior to that demonstrated by the midwifes. The physicians, in fact, demonstrated a significant improvement with respect to their pre-course knowledge. Both the physicians and the midwives showed a good level of expertise in manipulating the manipulating the manikin during the practical trial session. The midwifes and physicians almost unanimously manifested a high degree of approval of neonatal resuscitation by LMA, as they defined it a sustainable and cost-effective method requiring minimal expertise.Further studies are warranted to test the advantages and limits of the neonatal LMA training courses in developing countries.

Project description:Laryngeal mask airway (LMA) may be considered by health caregivers of level I-II hospitals for neonatal resuscitation and stabilization before and during interhospital care, but literature provides little information on this aspect. This study reviewed the use of LMA during stabilization and transport in a large series of neonates. This is a retrospective study evaluating the use of LMA in infants who underwent emergency transport by the Eastern Veneto Neonatal Emergency Transport Service between January 2003 and December 2021. All data were obtained from transport registry, transport forms, and hospital charts. In total, 64/3252 transferred neonates (2%) received positive pressure ventilation with an LMA, with increasing trend over time (p = 0.001). Most of these neonates were transferred after birth (97%), due to a respiratory or neurologic disease (95%). LMA was used before the transport (n = 60), during the transport (n = 1), or both (n = 3). No device-related adverse effects were recorded. Sixty-one neonates (95%) survived and were discharged/transferred from the receiving center.ConclusionIn a large series of transferred neonates, LMA use during stabilization and transport was rare but increasing over time, and showed some heterogeneity among referring centers. In our series, LMA was safe and lifesaving in "cannot intubate, cannot oxygenate" situations. Future prospective, multicenter research may provide detailed insights on LMA use in neonates needing postnatal transport.What is known• A supraglottic airway device may be used as an alternative to face mask and endotracheal tube during neonatal resuscitation. • The laryngeal mask may be considered by health caregivers of low-level hospitals with limited exposure on airway management, but literature provides little information on this aspect.What is new• In a large series of transferred neonates, laryngeal mask use was rare but increasing over time, and showed some heterogeneity among referring centers. • The laryngeal mask was safe and lifesaving in "cannot intubate, cannot oxygenate" situations.

Project description:The Guardian Laryngeal Mask Airway (G-LMA) is a new silicone-based single-use extraglottic device with the drainage port and a cuff pilot valve with pressure indicator. The aim of this study is to compare the clinical performance of this laryngeal mask airway with ProSeal laryngeal mask airway (P-LMA).In this prospective randomized study, we included adult patients with ASA grading I and II scheduled for elective surgery requiring supine position under total intravenous anesthesia. The patients were randomly allocated to two groups, 40 in each. G-LMA and P-LMA were used in groups G and P respectively. The cuff of each device was air inflated to 60 cmH2O. The primary outcome was to compare the airway sealing pressure and the secondary outcome was to compare the efficacy and safety of these two devices with respect to insertion success, insertion time, ease of insertion, volume of air for cuff inflation to 60 cmH2O, intracuff pressure measurement, gastric tube insertion attempt, gastric tube insertion time, Fiberoptic laryngeal view, and postoperative pharyngolaryngeal morbidity.The airway sealing pressure at 60 cmH2O cuff pressure was significantly greater in G-LMA than P-LMA (p?=?0.04).The first successful attempt of both groups were comparable (p?=?1.000). Insertion time was significantly shorter in G-LMA than P-LMA (p?<?0.0001). The first successful attempt for the gastric tube insertion in both groups was comparable (p?=?0.431). Gastric tube insertion time was less in G-LMA than in P-LMA (p?<?0.0001). The volume of air for cuff inflation to 60 cmH2O was more in G-LMA than in P-LMA (<0.0001). The intracuff pressure measurement at 30, 60, 90 and 120 minutes were comparable (p?=?0.823, 0.182, 0.870, 0.658).We did not find differences in ease of insertion (p?=?0.60); Fiber-optic positions of airway devices were comparable (p?=?0.83). In addition, blood staining (p?=?1.00), sore throat and dysphagia at 1, 2 and 24 hour (p?=?1.00) were comparable in both groups.The Guardian laryngeal mask airway was associated with high airway sealing pressure with a quicker insertion of the device as well as gastric tube.Clinical Trial.gov Identifier: NCT02063516.

Project description:The most important action in the resuscitation of a newborn in the delivery room is to establish effective assisted ventilation. The face mask and endotracheal tube are the devices used to achieve this goal. Laryngeal mask airways that fit over the laryngeal inlet have been shown to be effective for ventilating newborns at birth and should be considered as an alternative to facemask ventilation or endotracheal intubation among newborns weighing >2,000 g or delivered ?34 weeks' gestation. A recent systematic review and meta-analysis of supraglottic airways in neonatal resuscitation reported the results of four randomized controlled trials (RCTs) stating that fewer infants in the group using laryngeal mask airways required endotracheal intubation (1.5%) compared to the group using face masks (12.0%). However, there were methodological concerns over all the RCTs including the fact that the majority of the operators in the trials were anesthesiologists.Our hypothesis is based on the assumption that ventilating newborns needing positive pressure ventilation with a laryngeal mask airway will be more effective than ventilating with a face mask in a setting where neonatal resuscitation is performed by midwives, nurses, and pediatricians. The primary aim of this study will be to assess the effectiveness of the laryngeal mask airway over the face mask in preventing the need for endotracheal intubation.This will be an open, prospective, randomized, single center, clinical trial. In this study, 142 newborns weighing >1,500 g or delivered ?34 weeks gestation needing positive pressure ventilation at birth will be randomized to be ventilated with a laryngeal mask airway (LMA SupremeTM, LMA Company, UK - intervention group) or with a face mask (control group).Proportion of newborns needing endotracheal intubation.Apgar score at 5 minutes, time to first breath, onset of the first cry, duration of resuscitation, death or moderate to severe hypoxic-ischemic encephalopathy within 7 days of life.ClinicalTrials.gov identifier: NCT01963936 (October 11, 2013).
