Tracheal intubation while wearing personal protective equipment in simulation studies: a systematic review and meta-analysis with trial-sequential analysis.

BACKGROUND: Tracheal intubation in patients with coronavirus disease-19 is a high-risk procedure that should be performed with personal protective equipment (PPE). The influence of PPE on operator's performance during tracheal intubation remains unclear. METHODS: We conducted a systematic review and meta-analysis of simulation studies to evaluate the influence of wearing PPE as compared to standard uniform regarding time-to-intubation (TTI) and success rate. Subgroup analyses were conducted according to device used and operator's experience. RESULTS: The TTI was prolonged when wearing PPE (eight studies): Standard Mean Difference (SMD) -0.54, 95% Confidence Interval [-0.75, -0.34], p <  0.0001. Subgroup analyses according to device used showed similar findings (direct laryngoscopy, SMD -0.63 [-0.88, -0.38], p < 0.0001; videolaryngoscopy, SMD -0.39 [-0.75, -0.02], p =  0.04). Considering the operator's experience, non-anesthesiologists had prolonged TTI (SMD -0.75 [-0.98, -0.52], p < 0.0001) while the analysis on anesthesiologists did not show significant differences (SMD -0.25 [-0.51, 0.01], p = 0.06). The success rate of tracheal intubation was not influenced by PPE: Risk Ratio (RR) 1.02 [1.00, 1.04]; p = 0.12). Subgroup analyses according to device demonstrated similar results (direct laryngoscopy, RR 1.03 [0.99, 1.07], p = 0.15, videolaryngoscopy, RR 1.01 [0.98, 1.04], p =  0.52). Wearing PPE had a trend towards negative influence on success rate in non-anesthesiologists (RR 1.05 [1.00, 1.10], p = 0.05), but not in anesthesiologists (RR 1.00 [0.98, 1.03], p = 0.84). Trial-sequential analyses for TTI and success rate indicated robustness of both results. CONCLUSIONS: Under simulated conditions, wearing PPE delays the TTI as compared to dressing standard uniform, with no influence on the success rate. However, certainty of evidence is very low. Performing tracheal intubation with direct laryngoscopy seems influenced to a greater extent as compared to videolaryngoscopy. Similarly, wearing PPE affects more the non-anesthesiologists subgroup as compared to anesthesiologists.

Continuous Erector Spinae Plane Block as Postoperative Analgesic Technique for Robotic-Assisted Thoracic Surgery: A Case Series.

INTRODUCTION: The erector spinae plane block (ESPB) is a recently implemented analgesic technique initially reported for thoracic analgesia and subsequently adopted for both intra- and postoperative pain management. Thoracic surgery is among the most painful surgical procedures, even when conducted with minimally invasive approach. Robotic-assisted thoracic surgery (RATS) challenges the traditional analgesic regimens as one of its aims is to decrease the patient's length of stay (LOS) whilst achieving optimal postoperative pain management. Furthermore, there is lots of growing evidence on the impact of poorly controlled postoperative pain (PP) on the development of chronic post-surgical pain (CPSP). In these case series, we aim to describe our preliminary experience of postoperative pain management with continuous ESPB in the field of RATS. CASE SERIES PRESENTATION: In eight consecutive patients undergoing elective RATS procedure, we performed the ESPB after surgery with an initial bolus of local anesthetic followed by catheter insertion for continuous infusion. The infusion of local anesthetic lasted for the first two postoperative days. The effectiveness of the ESPB was evaluated through serial pain assessment with numeric rate scale (NRS) score, both at rest and during movement every 6 hours. Any analgesic rescue drug prescription was reported. We noted that the ESPB strongly reduced the prescription of opioids and of rescue analgesic. In our series, only one patient needed opioids during the first two postoperative days, and no rescue analgesic administration was noted in the remaining cases. CONCLUSION: We report a small but promising experience regarding postoperative pain management with continuous ESPB performed after RATS. We implemented the ESPB before surgery. Larger studies on postoperative pain management with continuous regional blocks in thoracic surgery are warranted.

Echocardiographic Parameters and Mortality in Pediatric Sepsis: A Systematic Review and Meta-Analysis.

OBJECTIVE: We conducted a systematic review and meta-analysis to investigate the prognostic value of echocardiographic parameters in pediatric septic patients. DATA SOURCES: MEDLINE, PubMed, and EMBASE (last update April 5, 2020). STUDY SELECTION: Observational studies of pediatric sepsis providing echocardiographic parameters in relation to mortality. DATA EXTRACTION: Echocardiography data were categorized as those describing left ventricular systolic or diastolic function, right ventricular function, and strain echocardiography parameters. Data from neonates and children were considered separately. Analysis is reported as standardized mean difference and 95% CI. DATA SYNTHESIS: We included data from 14 articles (n = 5 neonates, n = 9 children). The fractional shortening was the most commonly reported variable (11 studies, n = 555 patients) and we did not identify an association with mortality (standardized mean difference 0.22, 95% CI [-0.02 to 0.47]; p = 0.07, I2 = 28%). In addition, we did not find any association with mortality also for left ventricular ejection fraction (nine studies, n = 417; standardized mean difference 0.06, 95% CI [-0.27 to 0.40]; p = 0.72, I2 = 51%), peak velocity of systolic mitral annular motion determined by tissue Doppler imaging wave (four studies, n = 178; standardized mean difference -0.01, 95% CI [-0.34 to 0.33]; p = 0.97, I2 = 0%), and myocardial performance index (five studies, n = 219; standardized mean difference -0.51, 95% CI [-1.10 to 0.08]; p = 0.09, I2 = 63%). However, in regard to left ventricular diastolic function, there was an association with mortality for higher early wave of transmitral flow/peak velocity of early diastolic mitral annular motion determined by tissue Doppler imaging ratio (four studies, n = 189, standardized mean difference -0.45, 95% CI [-0.80 to -0.10]; p = 0.01, I2 = 0%) or lower peak velocity of early diastolic mitral annular motion determined by tissue Doppler imaging wave (three studies, n = 159; standardized mean difference 0.49, 95% CI [0.13-0.85]; p = 0.008, I2 = 0%). We did not find any association with mortality for early wave of transmitral flow/late (atrial) wave of trans-mitral flow ratio (six studies, n = 273; standardized mean difference 0.28, 95% CI [-0.42 to 0.99]; p = 0.43, I2 = 81%) and peak velocity of systolic mitral annular motion determined by tissue Doppler imaging wave measured at the tricuspid annulus (three studies, n = 148; standardized mean difference -0.18, 95% CI [-0.53 to 0.17]; p = 0.32, I2 = 0%). Only a few studies were conducted with strain echocardiography. CONCLUSIONS: This meta-analysis of echocardiography parameters in pediatric sepsis failed to find any association between the measures of left ventricular systolic or right ventricular function and mortality. However, mortality was associated with higher early wave of transmitral flow/peak velocity of early diastolic mitral annular motion determined by tissue Doppler imaging or lower peak velocity of early diastolic mitral annular motion determined by tissue Doppler imaging, indicating possible importance of left ventricular diastolic dysfunction. These are preliminary findings because of high clinical heterogeneity in the studies to date.

Pregnancy in an Asymptomatic Woman with Porencephalic and Arachnoid Cysts.

A 25-year-old woman presented to the obstetric clinic in her first pregnancy. The patient was accompanied by her mother who reported an episode of intracerebral hemorrhage after birth and also remembered access to the emergency department after generalized tonic-clonic seizure as an infant. She was not able to describe the therapy for seizure preventions and even when and why it was suspended, but she affirmed that no residual neurological consequences were detected in the following years. Actually, the pregnant woman was in good health without neurological symptoms nor assumed any therapy. A neurologist reviewed the patient's CT scan in which arachnoid cyst and porencephalic cyst were evident, and he assessed that no abnormalities were found in motor, sensory, and mental state examination. EEG did not show any epileptiform or seizure-like activity. No antiepileptic drug was prescribed due to the absence of symptoms since many years. The patient had no neurological symptoms during pregnancy or obstetric complications and delivered at term a healthy baby through a caesarean section. She breastfed, and after two years, the patient and the baby are healthy. The association of porencephalic and arachnoid cyst in pregnancy is an extremely rare neurological condition that needs a multidisciplinary counseling in pregnancy, but an uneventful course is possible.
