“…Specific for obstetric anaesthesia, limited evidence from a series of 180 intubations for emergency or urgent caesarean section shows that the use of videolaryngoscopy ensured successful intubation at the first attempt in all 18 patients in which it was used as the primary device. Furthermore, it was used as a rescue device during a failed intubation with direct laryngoscopy . It is now widely recognised that videolaryngoscopy has a critical role to play in obstetric general anaesthesia .…”

“…Aziz et al was the only non-randomized study where ROBINS-I could be conducted, and it was evaluated to be at serious risk of bias due to the possibility of confounding in the study design. 63 Kurvey et al did not present sufficient information in their published abstract to fairly judge the risk of bias. 64 Some concerns were uncovered in all RCTs for the potential of bias in the measurement of the outcome as assessors were not blinded to the allocated interventions.…”

The incidence of difficult and failed intubation is higher in obstetrical patients than in the general population because of anatomic and physiologic changes in pregnancy. Videolaryngoscopy improves the success rate of intubation and reduces complications when compared with direct laryngoscopy in adults; however, it is not known whether this extends to obstetrical surgery. The aim of this study was to examine the efficacy, efficiency, and safety of videolaryngoscopy compared with direct laryngoscopy in obstetrics. Source Central, CINAHL, Embase, MEDLINE and Web of Science databases were searched from inception to 27 May 2020 with no restrictions. Inclusion criteria included randomized-controlled trials (RCTs), observational studies, case series, and case reports that reported the application of videolaryngoscopy to intubate the trachea in pregnant patients having general anesthesia. Principal findings Overall, four RCTs with 428 participants, nine observational studies, and 35 case reports/series with 100 participants were included. On meta-analysis of three trials, the co-primary outcomes of first-attempt success rate (risk ratio, 1.02; 95% confidence intervals [CI], 0.98 to 1.06; P = 0.29; I 2 = 0%) and time to tracheal intubation (mean difference, 1.20 sec; 95% CI,-6.63 to 9.04; P = 0.76; I 2 = 95%) demonstrated no difference between videolaryngoscopy and direct laryngoscopy in parturients without difficult airways. Observational studies and case reports underline the role of videolaryngoscopy as a primary choice when difficulty with tracheal intubation is expected or as a rescue modality in difficult or failed intubations. Conclusions Evidence for the utility of videolaryngoscopy continues to evolve but supports its increased adoption in obstetrics where videolaryngoscopes should be immediately available for use as a first-line device.

“…However, one should be comfortable using one of the videolaryngoscope products and one other technique. 99 In addition, there are more invasive alternatives such as needle cricothyrotomy, retrograde wire intubation, and open cricothyrotomy should an SGD or other alternative to direct laryngoscopy fail and one has still not secured the airway in the face of rapidly deteriorating oxygenation. 96,97 The Glidescope has been specifically shown to improve the success at intubation in normal airways, those with predictors of direct laryngoscopy, and as a rescue device in a recent study of over 2000 intubations, and therefore may be a reasonable first choice in a patient deemed to have an "awkward" airway.…”
