Abstract
BACKGROUND Premedication in neonates undergoing elective intubation effectively minimizes the negative physiological events of bradycardia, systemic hypertension, intracranial hypertension, and hypoxia. Premedication decreases procedure-related pain and discomfort. This study aimed to evaluate the current practice of pre-intubation medications for non-emergent intubations in preterm and term neonates in the United States. STUDY DESIGN A cross-sectional survey (Appendix) was sent via e-mail to all level 3 and 4 Neonatal Intensive Care Units (NICUs) of the Organization of Neonatal Perinatal Medicine Training Program Directors (ONTPD), NICU directors with pediatric residency only, and Baylor Scott and White Health, Mednax, and Envision health services systems. RESULTS Of 170 responses, 41% (69/168) routinely premedicate, 38% (64/168) premedicate under specific circumstances, and 21% (35/168) do not administer any routine pre-intubation medications. Only 46% (77/168) of units had a written policy. The most frequently used drugs were fentanyl (68%, 116/170), atropine (39%, 66/170), midazolam (38%, 64/170), and morphine (26%, 45/170). 21% (36/170) used a two-drug combination, and 38% (64/170) used a three-drug combination. The most commonly used two-drug combination was atropine and fentanyl, and the most common three-drug combination was atropine, fentanyl, and a paralytic agent. CONCLUSION Despite the well-documented benefits of premedication for NICU intubations, as aligned with AAP recommendations, the US lags behind other nations, with stagnant rates since 2006. This disparity persists despite a rise in written policies, which exhibit significant content variations. The authors advocate for the adoption of standardized, AAP-aligned policies across all NICUs in the US. Continued research is vital to monitor the progress of this crucial practice and address any underlying barriers to implementation.

Abstract
To compare the therapeutic effect of less invasive surfactant administration (LISA) followed by synchronized nasal intermittent positive pressure ventilation (SNIPPV) and traditional intubate-Surfactant-Extubate (InSurE) strategy for the treatment of neonatal respiratory distress syndrome (NRDS). A single-center, non-randomized and single- blinded study Tertiary neonatal intensive care unit 89 infants enrolled were preterm with gestational age < 366/7 weeks and clinically diagnosed with neonatal RDS (NRDS) Interventions: 32 infants were assigned to the LISA + SNIPPV group and 57 infants to the InSurE + nCPAP group. No statistically significant differences were noted in the baseline characteristics of the enrolled infants. A lower proportion of infants developed BPD in the LISA + SNIPPV group compared to the InSurE + CPAP group [10 (31.25%) vs. 21 (36.84%), P > 0.05]; however, there was no statistically significant difference. The number needed to treat (NNT) with LISA + SNIPPV to prevent BPD development is 18. The mortality rate was not significant between our study arms [1 (3.13%) vs 2 (3.51%), P > 0.05]. There were no statistically significant differences in the durations (days) of MV [(12.18 ± 13.89) vs. (11.35 ± 11.61), P > 0.05], oxygen therapy [(35.03 ± 19.13) vs. (39.75 ± 17.91), P > 0.05] and re-intubation rates [(0.19 ± 0.40) vs. (0.21 ± 0.45), P > 0.05] between the two study groups. In terms of complications, the incidence of patent ductus arteriosus (PDA) [24 (75.00%) vs. 27 (47.37%), P < 0.05] was higher and a lower rate of disturbed liver function [1 (3.23%) vs. 19 (33.33%), P < 0.05] were observed in the LISA + SNIPPV group. Acid-base imbalances were reportedly significantly higher in the InSurE group (P < 0.05). No significant differences in other complications were noted. In the interventional group, FiO2 requirements were significantly lower up until the 3rd week of treatment [FiO2 at day 0, (30.75 ± 4.78) vs. (34.66 ± 9.83), P < 0.05; FiO2 at day 21, (25.32 ± 3.74) vs. (29.11 ± 8.17), P < 0.05], as was RSS on days 2 [(0.77 ± 0.38) vs. (1.94 ± 0.75), P < 0.05] and 3 [(0.66 ± 0.33) vs. (1.89 ± 0.82), P < 0.05] after treatment. Additionally, infants in the standard group had a significantly prolonged hospital stay (days) [(45.97 ± 16.93) vs. (54.40 ± 16.26), P < 0.05]. The combination of LISA and SNIPPV for NRDS can potentially lower the rate of BPD, FiO2 demand and shorten the length of hospitalization.

Abstract
PURPOSE To determine the safety and efficacy of ketamine analgesia as an alternative to general anesthesia during laser treatment for retinopathy of prematurity (ROP). METHODS Eighteen premature neonates with ROP underwent laser treatment. The procedure was performed in the operating room, and the neonates were admitted to the neonatal intensive care unit (NICU) after the procedure. An initial dose of 1 mg/kg of ketamine was administered. If the neonate exhibited movement or distress during the procedure, incremental doses of ketamine were administered. Perioperative ventilation status, severity of pain during the procedure, surgeon satisfaction, and perioperative events were recorded. RESULTS Eighteen premature neonates underwent ketamine analgesia during laser treatment for ROP. The procedure was performed in 16 patients with good tolerance and without events. The Premature Infant Pain Profile (PIPP) scores during the procedure were 5 or less in 12 neonates (44.4%), 5 to 10 in 4 neonates (22.2%), and greater than 10 in 2 (11.1%) neonates. Three neonates had perioperative events, which resolved completely with minimal intervention. None of the neonates needed intubation perioperatively, and hemodynamic instability, hypotension, and bradycardia were not recorded in any of the neonates during or after the procedure. CONCLUSIONS The ROP laser treatment under ketamine sedation could be performed in premature neonates with few perioperative complications and provide satisfactory operative conditions.

Abstract
This systematic review evaluates research regarding the use of premedication for nonemergent neonatal intubation. Unmedicated intubation is associated with adverse outcomes such as physiologic instability and decompensation, repeat and prolonged intubation attempts, and trauma. Included studies compared medicated intervention groups against an unmedicated control. Medications vary greatly across studies and include anesthetics, opioids, benzodiazepines, barbiturates, vagolytics, and neuromuscular blockades (muscle relaxants). A comprehensive search of randomized control trials, retrospective cohort studies, and prospective observational studies was completed from the electronic databases of CINAHL EBSCOhost, Ovid MEDLINE, PubMed, EMBASE, Google Scholar, Cochrane Collaboration, and ClinicalTrials.gov and footnotes were used to complete the search. Twelve studies are included in this review dating back to 1984 and are from 5 countries. Outcome measures include changes in heart rate, oxygen saturation, and blood pressure; number and duration of attempts to intubate; and trauma to the oral cavity and upper airway. Twelve studies are included in this review and include 5410 patients. No studies were excluded based on level of evidence or quality appraisal. Findings in this review support the recommendation that opioids and vagolytic agents should be used for premedication for nonemergent neonatal intubation and adjuvant sedation and muscle relaxants should be considered.

Abstract
BACKGROUND Surfactant therapy is the cornerstone of respiratory distress syndrome management. "Less-invasive surfactant administration (LISA)" is now recommended for spontaneously breathing preterm infants. Analgosedation remains controversial as 52% of European neonatologists do not use any. This systematic review aims to describe the efficacy and safety of different drugs for analgosedation during LISA. METHODS MEDLINE via Ovid, Embase, Scopus, and Cochrane Library of Trials were searched independently by 2 reviewers for studies on sedation or analgesia for LISA, without filters or limits. RESULTS Eight studies (1 randomized controlled trial) recruiting 945 infants were included. Infant pain was significantly reduced, with more infants evaluated as comfortable. Failure, defined as need for intubation or for a second dose of surfactant, was not different between sedated and unsedated groups. Analgosedation was associated with a higher occurrence of desaturation and need for positive pressure ventilation during procedure, but the need for mechanical ventilation within 24 or 72 h of life was not significantly different. There does not seem to be any difference in clinical tolerance and complications (e.g., hypotension, mortality, air leaks, etc.). Procedural conditions were evaluated as good or excellent in 83% after sedation. DISCUSSION AND CONCLUSION Analgesia or sedative drugs increase infant comfort and allow good procedural conditions, with a limited impact on the clinical evolution. Questions remain about the best choice of drugs and dosages, with the constraint to maintain spontaneous breathing and have a rapid offset. Further good quality studies are needed to provide additional evidence to supplement those limited existing data.

Abstract
OBJECTIVE To find propofol doses providing effective sedation without side effects in neonates of different gestational ages (GA) and postnatal ages (PNA). DESIGN AND SETTING Prospective multicentere dose-finding study in 3 neonatal intensive care units. PATIENTS Neonates with a PNA <28 days requiring non-emergency endotracheal intubation. INTERVENTIONS Neonates were stratified into 8 groups based on GA and PNA. The first 5 neonates in every group received a dose of 1.0 mg/kg propofol. Based on sedative effect and side effects, the dose was increased or decreased in the next 5 patients until the optimal dose was found. MAIN OUTCOME MEASURES The primary outcome was the optimal single propofol starting dose that provides effective sedation without side effects in each age group. RESULTS After inclusion of 91 patients, the study was prematurely terminated because the primary outcome was only reached in 13% of patients. Dose-finding was completed in 2 groups, but no optimal propofol dose was found. Effective sedation without side effects was achieved more often after a starting dose of 2.0 mg/kg (28%) than after 1.0 mg/kg (3%) and 1.5 mg/kg (9%). Propofol-induced hypotension occurred in 59% of patients. Logistic regression analyses showed that GA and PNA did not predict effective sedation or the occurrence of hypotension. CONCLUSIONS Effective sedation without side effects is difficult to achieve with propofol and the optimal dose in different age groups of neonates could not be determined. The sedative effect of propofol and the occurrence of hypotension are unpredictable and show large inter-individual variability in the neonatal population.

Abstract
Non-invasive ventilation is currently the preferred respiratory support for premature infants with respiratory distress. The lung-protective effects of non-invasive ventilation should however not prompt disregard for the possible pain and discomfort it can generate. Non-pharmacological interventions should be used in all premature infants, regardless of their respiratory support, and are not detailed in this review. This review includes currently available evidence and gaps in knowledge regarding three aspects of pain management in premature infants receiving non-invasive ventilation: optimisation of non-invasive ventilation especially through the choice of positive pressure source, appropriate interface and synchronisation; sedative or analgesic drug use for strategies aiming at administering surfactant with reduction or avoidance of tracheal ventilation; risks and benefits of some analgesic and/or sedative drugs used to treat or prevent prolonged pain and discomfort during non-invasive ventilation. In spite of limited robust evidence, this overview should trigger caregivers' reflections on their daily practice.

Efficacy, Safety, and Usability of Remifentanil as Premedication for INSURE in Preterm Neonates. CHILDREN-BASEL 2018; 5:children5050063. [PMID: 29789465 PMCID: PMC5977045 DOI: 10.3390/children5050063] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/24/2018] [Revised: 05/15/2018] [Accepted: 05/19/2018] [Indexed: 01/06/2023]
Abstract
Background: We previously reported a 67% extubation failure with INSURE (Intubation, Surfactant, Extubation) using morphine as analgosedative premedication. Remifentanil, a rapid- and short-acting narcotic, might be ideal for INSURE, but efficacy and safety data for this indication are limited. Objectives: To assess whether remifentanil premedication increases extubation success rates compared with morphine, and to evaluate remifentanil's safety and usability in a teaching hospital context. Methods: Retrospective review of remifentanil orders for premedication, at a large teaching hospital neonatal intensive care unit (NICU). We compared INSURE failure rates (needing invasive ventilation after INSURE) with prior morphine-associated rates. Additionally, we surveyed NICU staff to identify usability and logistic issues with remifentanil. Results: 73 remifentanil doses were administered to 62 neonates (mean 31.6 ± 3.8 weeks' gestation). Extubation was successful in 88%, vs. 33% with morphine premedication (p < 0.001). Significant adverse events included chest wall rigidity (4%), one case of cardiopulmonary resuscitation (CPR) post-surfactant, naloxone reversal (5%), and notable transient desaturation (34%). Among 137 completed surveys, 57% indicated concerns, including delayed drug availability (median 1.1 h after order), rapid desaturations narrowing intubation timeframes and hindering trainee involvement, and difficulty with bag-mask ventilation after unsuccessful intubation attempts. Accordingly, 33% of ultimate intubators were attending neonatologists, versus 16% trainees. Conclusions: Remifentanil premedication was superior to morphine in allowing successful extubation, despite occasional chest wall rigidity and unfavorable conditions for trainees. We recommend direct supervision and INSURE protocols aimed at ensuring rapid intubation.

Abstract
BACKGROUND Neonatal intubation is stressful and should be performed with premedication. In the case of an INSURE (intubation/surfactant/extubation) procedure a short duration of action of the premedication used is needed to facilitate fast extubation. Given its pharmacological profile, remifentanil seems a suitable candidate. OBJECTIVES The aim here was to evaluate the effect and side effects of remifentanil as a premedication for preterm neonates undergoing INSURE. METHODS A prospective, single-center study in a level III neonatal intensive care unit was conducted. The quality of sedation was assessed in preterm infants receiving remifentanil prior to intubation for the INSURE procedure. Intravenous remifentanil was administered quickly and followed by a saline flush in approximately 30 s. The quality of sedation was defined by a combination of adequate sedation score, good intubation conditions and absence of side effects. RESULTS The study was terminated after the inclusion of 14 patients because of the high rate of side effects and the poor intubation conditions. Adequate sedation was achieved in only 2 patients (14%). Six patients (43%) needed additional propofol to obtain adequate sedation. Chest wall rigidity occurred in 6 patients (43%). CONCLUSIONS The rapid administration of remifentanil provides insufficient sedation and is associated with a high risk of chest wall rigidity in preterm neonates.

Abstract
OBJECTIVE To define the effective dose for 50% of patients (ED50) of propofol for successful intubation and to determine the rate of successful extubation in those patients with planned intubation, surfactant administration, and immediate extubation (INSURE procedure). In addition, pharmacodynamic effects were assessed. STUDY DESIGN Neonates (n = 50) treated with propofol for (semi-)elective endotracheal intubation were stratified in 8 strata by postmenstrual and postnatal age. The first patient in each stratum received an intravenous bolus of 1 mg/kg propofol. Dosing for the next patient was determined using the up-and-down method. A propofol ED50 dose was calculated in each stratum with an effective sample size of at least 6, via the Dixon-Masey method, with simultaneous assessment of clinical scores and continuous vital sign monitoring. RESULTS Propofol ED50 values for preterm neonates <10 days of age varied between 0.713 and 1.350 mg/kg. Clinical recovery was not attained at the end of the 21-minute scoring period. Mean arterial blood pressure showed a median decrease between 28.5% and 39.1% from baseline with a brief decrease in peripheral and regional cerebral oxygen saturation. Variability in mean arterial blood pressure area under the curve could not be explained by weight or age. CONCLUSIONS Low propofol doses were sufficient to sedate neonates for intubation. Clinical recovery was accompanied by permissive hypotension (no clinical shock and no treatment). The propofol ED50 doses can be administered at induction, with subsequent up-titration if needed, while monitoring blood pressure. They can be used for further dosing optimalization and validation studies. TRIAL REGISTRATION ClinicalTrials.gov: NCT01621373; EudraCT: 2012-002648-26.

Abstract
OBJECTIVES The aims of this study were to assess the efficacy and feasibility of a new, less invasive surfactant administration technique for beractant replacement using a specifically designed cannula in preterm infants born at <32 weeks of gestation and to compare short- and long-term outcomes between this approach and standard treatment, consisting of intubation, administration of surfactant and early extubation to nasal continuous positive airway pressure. METHOD This was a single-center, prospective, open-label, non-randomized, controlled pilot study with an experimental cohort of 30 patients treated with less invasive surfactant administration and a retrospective control group comprising the 30 patients most recently treated with the standard approach. Beractant (4 ml/kg) was administered as an exogenous surfactant in both groups if patients on nasal continuous positive airway pressure during the first three days of life were in need of more than 30% FiO2. Clinicaltrials.gov: NCT02611284. RESULTS In the group with less invasive surfactant administration, beractant was successfully administered in all patients. Thirteen patients (43.3%) in the group with less invasive surfactant administration required invasive mechanical ventilation for more than 1 hour during the first 3 days of life, compared with 22 (73%) in the control group (p<0.036). The rate of requiring invasive mechanical ventilation for more than 48 hours was similar between the infants in the two groups (46% vs. 40%, respectively). There were no differences in other outcomes. CONCLUSION The administration of beractant (4 ml/kg) using a less invasive surfactant administration technique with a specifically designed cannula for administration is feasible. Moreover, early invasive mechanical ventilation exposure is significantly reduced by this method compared with the strategy involving intubation, surfactant administration and early extubation.

Abstract
Background The INtubation-SURfactant-Extubation (INSURE) is a procedure that is increasingly being used to treat the respiratory distress syndrome in preterm infants. The objective of this study was to identify predictors for an unsuccessful INSURE procedure. Methods The neonates included were less than 32 weeks’ gestation, treated with surfactant in the neonatal intensive care unit, and born 1998–2010. INSURE was defined as surfactant administration during intubation for less than 2 hours without the need for mechanical ventilation. INSURE success was defined as no re-intubation within 72 hours after INSURE, and INSURE failure was defined as re-intubation within 72 hours after INSURE. An unsuccessful INSURE procedure was either INSURE failure or mechanical ventilation for more than 24 hours immediately after surfactant administration. All predictors were defined a priori and were present before surfactant administration. Multivariate logistic regression was performed. Results In total, 322 neonates were included: 31% (n = 100) had INSURE success, 10% (n = 33) had INSURE failure, 49% (n = 158) needed mechanical ventilation for more than 24 hours, and the remaining 10% (n = 31) needed mechanical ventilation for less than 24 hours. Predictors for INSURE failure were low gestational age and hemoglobin below 8.5 mmol/l. Predictors for mechanical ventilation for more than 24 hours were low gestational age, Apgar at 5 minutes below 7, oxygen need above 50%, CO2 pressure above 7 kPa (~53 mmHg), pH below 7.3, lactate above 2.5 mmol/l, need for inotropes, and surfactant administration shortly after birth, whereas preeclampsia reduced the risk. Conclusions We identified specific predictors associated with an unsuccessful INSURE procedure. Keeping high-risk neonates with one or several predictors intubated and treated with mechanical ventilation after surfactant may prevent a re-intubation procedure.
