However, several potential confounders influencing the link between anaesthetic techniques and postoperative depression were not specifically addressed in the analysis.</p>\u0000<p>First, pre-existing mental health conditions, such as a history of depression or anxiety, are established risk factors for postoperative depression. These conditions may also impact the choice of anaesthesia due to concerns around peri-operative psychological stress [<span>2</span>]. Additionally, socio-economic status, another crucial determinant of health, could confound the relationship between anaesthesia type and depression. Patients with lower socio-economic status may have limited access to certain anaesthesia options or an increased baseline risk of depression, irrespective of surgical factors [<span>3</span>].</p>\u0000<p>Second, chronic pain and the severity of pre-operative pain are important considerations. Over half of surgical patients experience inadequate postoperative pain management. Certain pre-operative psychological interventions can mitigate acute postoperative pain scores and reduce opioid consumption [<span>4</span>]. Social support and living conditions, although unmeasured confounders, also play a significant role. Social isolation and limited support networks are indirectly linked to surgical outcomes through their association with depression, which is itself associated with poorer outcomes [<span>5</span>]. These psychosocial factors may also impact the choice of anaesthesia.</p>\u0000<p>Finally, reliance on ICD-10 codes for diagnosing depression may result in an underestimation of its true incidence, as mental health disorders are frequently underdiagnosed or misclassified in clinical settings. This potential underreporting could distort the observed differences between anaesthesia groups, particularly if diagnostic practices vary among contributing institutions.</p>\u0000<p>To strengthen future research, incorporating validated mental health assessments pre- and post-surgery, as well as collecting data on socio-economic factors and social support networks could provide a more nuanced understanding of anaesthesia's role in postoperative depression.

Fung, Anna Preston","doi":"10.1111/anae.16555","DOIUrl":"https://doi.org/10.1111/anae.16555","url":null,"abstract":"<p>The comparison of dural puncture epidural (DPE) labour analgesia with other accepted techniques including combined spinal-epidural (CSE) and epidural alone is an interesting and debated topic. The recent paper by Zang et al. attempts to address this and concludes there were no significant differences in the quality of labour analgesia for DPE compared with the CSE technique [<span>1</span>]. We have concerns regarding the methodology and results of this paper and its clinical significance for DPE-related trials.</p>\u0000<p>First, the sample size calculation was assumed to detect a reduction in the composite primary outcome from 50% in the CSE group to 22.5% in the DPE group, based on previous calculations published by Chau et al. [<span>2</span>]. The most effective clinical interventions are, at most, modest in effect size [<span>3</span>], thus we argue that the authors used an overly optimistic prediction to calculate the minimum required sample size, which was done arbitrarily. A CSE vs. DPE would intuitively be a small effect size, thus using a small sample size would have insufficient power to evaluate this. Smaller effect sizes were most likely missed in this study due to the small sample size.</p>\u0000<p>Second, the primary and secondary outcomes were all focused on parameters affecting an anaesthetist's workload, except for the final secondary outcome which was the satisfaction of the mother with labour analgesia. The satisfaction scores for both CSE and DPE groups ranged from 0 to 10, which we argue is a crude and non-discriminating outcome measure. Currently, there is a lack of patient-reported outcome measure (PROM) questionnaires to capture the quality of maternity care, especially during labour [<span>4</span>]. Future studies investigating the quality of analgesia will need to include maternity PROMs, specifically focused on the intrapartum period. Furthermore, Zang et al. did not capture the rate of caesarean deliveries after neuraxial labour analgesia, which is a key outcome concerning the patient, obstetrician and anaesthetist. We argue that future clinical trials need to include a core outcome set for holistic and accurate measurements, which also allows for meta-analysis and homogeneity in data collection between individual trials [<span>5</span>].</p>\u0000<p>Finally, approaching the topic of labour analgesia from a holistic perspective, should we focus on the impact of an intentional dural puncture or access to labour analgesia? The clinical benefits of labour analgesia (regardless of technique) are well documented. Yet there are still disparities in access to labour analgesia, especially in socio-economically deprived parturients. A recent population-based study in Scotland found the utilisation of epidurals for labour analgesia was 22%, and women in the most deprived areas were 16% less likely to receive epidural analgesia compared with the most affluent [<span>6</span>].

We would like to highlight several practice point considerations relating to use of such systems.</p>\u0000<p>A limitation of previous designs is that applying a tight-fitting anaesthetic facemask over the incompressible nasal prongs is contraindicated due to the risks of gastric insufflation and barotrauma. The Fisher and Paykel Optiflow™ Switch (Fisher and Paykel, Auckland, New Zealand) modification [<span>2</span>] incorporates a flow-regulated pressure relief valve and a compressible inflow to the nasal prongs so that there is interruption of the 100% oxygen nasal prong gas flow when a tight-fitting facemask is applied. This allows safe and seamless transitions from anaesthetic mask pre-oxygenation and facemask ventilation to HFNO and vice versa.</p>\u0000<p>The user should be aware that, even when a firmly applied facemask is applied over the nasal prongs, the nasal oxygen flow is not completely ‘switched off’. It is likely to be variable but with Optiflow Switch flows above 10 l.min<sup>-1</sup> it is apparent that there is ongoing oxygen ingress via the nasal prongs into the facemask during pre-oxygenation and facemask ventilation. The product literature details that the pressure delivered to the patient will be limited to 30 cmH<sub>2</sub>O between flows of 30–70 l.min<sup>-1</sup> [<span>3</span>].</p>\u0000<p>Figure 1 shows the gas analyser data observed when a firmly applied facemask connected to a circle anaesthetic circuit with flow rates 10 l.min<sup>-1</sup> of room air (F<sub>I</sub>O<sub>2</sub> 0.21) is applied over the Optiflow Switch nasal prongs and the HFNO flow rate is increased. The analyser measures increasing levels of inspired and end-tidal oxygen consistent with increasing oxygen ingress via the nasal prongs. Additionally, the capnography trace is attenuated, the extent of which is related to the HFNO flow rate. It does not appear to make a significant difference if the mask is a cushion design (e.g. Ambu® King; Ambu A/S, Ballerup, Denmark) or anatomical (e.g. Meditech Anatomical Eco; Meditech Systems Limited, Shaftesbury, UK).</p>\u0000<figure><picture>\u0000<source media=\"(min-width: 1650px)\" srcset=\"/cms/asset/4281cadf-7e16-42ba-9ad4-786dd478abb4/anae16547-fig-0001-m.jpg\"/><img alt=\"Details are in the caption following the image\" data-lg-src=\"/cms/asset/4281cadf-7e16-42ba-9ad4-786dd478abb4/anae16547-fig-0001-m.jpg\" loading=\"lazy\" src=\"/cms/asset/89be1ca2-6d77-48de-8576-478a34442fb5/anae16547-fig-0001-m.png\" title=\"Details are in the caption following the image\"/></picture><figcaption>\u0000<div><strong>Figure 1<span style=\"font-weight:normal\"></span></strong><div>Open in figure viewer<i aria-hidden=\"true\"></i><span>PowerPoint</span></div>\u0000</div>\u0000<div>Photos stitched together show representative gas analyser readi","PeriodicalId":7742,"journal":{"name":"Anaesthesia","volume":"34 1","pages":""},"PeriodicalIF":10.7,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143026690","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
