Association of Pain Catastrophizing with Postnatal Depressive States in Nulliparous Parturients: A Prospective Study

The correlation between quality of recovery and parturient outcomes after Cesarean delivery: a cohort study

PURPOSE

Recent studies have reported the use of the obstetric-specific quality of recovery tool (ObsQoR-10) to assess the quality of recovery in parturients after childbirth; however, the correlation between ObsQoR-10 scores and important postpartum outcomes are unclear. The primary aim of the present study was to investigate the correlations between ObsQoR-10 scores at 24 hr after Cesarean delivery and breastfeeding, depressive symptomatology, overall health, and pain at seven days postpartum.

METHODS

We recruited parturients who underwent elective Cesarean delivery at KK Hospital in Singapore. Parturients provided responses to post-Cesarean questionnaires at 1) 24 hr (ObsQoR-10, EuroQol EQ-Visual Analogue Scale, Edinburgh Postnatal Depression Scale), 2) 48 hr (ObsQoR-10, EQ-Visual Analogue Scale), and 3) seven days after Cesarean delivery (ObsQoR-10, Breastfeeding Self-Efficacy Scale-Short form, EQ-Visual Analogue Scale, Edinburgh Postnatal Depression Scale, pain survey).

RESULTS

We enrolled 222 participants, 200 (90%) of whom completed the seven-day follow-up between September 2022 and April 2023. There was limited correlation between ObsQoR-10 at 24 hr with the Edinburgh Postnatal Depression Scale (r = 0.135), EQ-Visual Analogue Scale (r = 0.158), Breastfeeding Self-Efficacy Scale-Short form (r = 0.225), and averaged pain scores (r = -0.107) at seven days postpartum. ObsQoR-10 breastfeeding sub-score at 24 hr was weakly correlated with Breastfeeding Self-Efficacy Scale-Short form at seven days postpartum (r = 0.307).

CONCLUSION

ObsQoR-10 at 24 hr postpartum had limited correlation with breastfeeding, depressive symptomatology, overall health, and pain at seven days.

The association between epidural labour analgesia and postpartum depression: a randomised controlled trial

There is conflicting evidence regarding the association between epidural labour analgesia and risk of postpartum depression. Most previous studies were observational trials with limited ability to account for confounders. We aimed to determine if epidural analgesia was associated with a significant change in the incidence of postpartum depression in this randomised controlled trial. We enrolled women aged 21-50 years old with a singleton fetus ≥ 36 weeks gestation. Patients were advised regarding available labour analgesic modalities during enrolment (epidural block; intramuscular pethidine; nitrous oxide; or intravenous remifentanil). On request for analgesia, patients were offered the modality that they had been allocated randomly to first. Blinded investigators recorded patient and obstetric characteristics within 24 h of delivery and assessed for postpartum depression at 6-10 weeks following delivery using the Edinburgh Postnatal Depression Scale (score ≥ 13 considered positive for postpartum depression). The modified intention-to-treat population consisted of all patients who received any form of labour analgesia, while per-protocol consisted of patients who received their randomised modality as their first form of labour analgesia. Of 881 parturients allocated randomly (epidural n = 441, non-epidural n = 440), we analysed 773 (epidural n = 389, non-epidural n = 384); 62 (15.9%) of women allocated to epidural group developed postpartum depression compared with 65 (16.9%) women allocate to the non-epidural group. There were no significant differences in the incidence of postpartum depression between the two groups (adjusted risk difference (95%CI) 1.6 (-3.0-6.3%), p = 0.49). Similar results were obtained with per-protocol analysis (adjusted risk difference (95%CI) -1.0 (-8.3-6.3%), p = 0.79). We found no significant difference in the risk of postpartum depression between patients who received epidural labour analgesia and those who utilised non-epidural analgesic modalities.

Sub-acute pain after childbirth during COVID-19 pandemic: A secondary analysis of A prospective clinical trial

Background

COVID-19 pandemic could bring great impact upon the psychological statuses of post-partum women, but no clear evidence was provided yet as to COVID-19 would also affect their pain profile during post-partum period. We determined if pain and psychological vulnerabilities, obstetric factors, and labor analgesia were associated with sub-acute pain after childbirth (SAPC; ongoing pain related to delivery at post-partum 4 weeks or more) during COVID-19 pandemic.

Methods

We included women having a singleton pregnancy of ≥36 gestational weeks. The recruited women were given pre-delivery questionnaires to measure their pain and psychological vulnerabilities. At post-partum 6-10 weeks, an online survey was conducted to collect data on post-partum pain information.

Results

Of the 880 recruited women, 816 completed the post-partum pain survey, with 99 (12.1%) having developed SAPC. Giving birth during COVID-19 pandemic (adjusted odds ratio (aOR) 1.64, 95%CI 1.04 to 2.57), greater pre-delivery central sensitization (aOR 1.02, 95%CI 1.00 to 1.04), greater number of pain relief administered (aOR 1.49, 95%CI 1.18 to 1.89), having had artificial rupture of membrane and oxytocic during labor onset (aOR 3.00, 95%CI 1.66 to 5.40), greater volume of blood loss during delivery (every 100 ml; aOR 1.27, 95%CI 1.11 to 1.44), having had third-degree tear during delivery (aOR 4.40, 95%CI 1.33 to 14.51), and greater infant height (aOR 1.14, 95%CI 1.01 to 1.30) were independently associated with greater risk of SAPC. Having greater general health score was protective against the risk of SAPC (aOR 0.99, 95% CI 0.97 to 0.999) (Area under the curve (AUC) = 0.74).

Conclusions

The generated multivariable association model may help us better understand the shift in pain and psychological aspects of women during COVID-19 pandemic.

Association of pain catastrophizing with labor pain and analgesia consumption in obstetrical patients

INTRODUCTION

Pain catastrophizing is an exaggerated negative orientation to painful stimuli which in obstetric patients is associated with fear of overwhelming labor pain and negative pain-related outcomes. This study aimed to quantitatively examine the association of pain catastrophizing with maternal labor pain outcomes.

METHODS

We conducted a prospective observational study of women admitted for a vaginal trial of labor. Subjects completed the 13-item Pain Catastrophizing scale (PCS) questionnaire (scored 0 to 52, higher scores representing greater catastrophizing). Pain was assessed at baseline and at request for neuraxial labor analgesia. Labor and postpartum pain intensity was assessed as the average area under the pain intensity by time curve. Pain at request for analgesia, labor pain, postpartum pain, analgesic consumption, and quality of recovery was compared between high (PCS ≥ 17) and low catastrophizing groups.

RESULTS

Data from 138/157 (88%) subjects were included in the analysis. Median (IQR) pain scores at request for analgesia were 9 (8,10) and 8 (6,9), a difference of 1 (95% CI 0 to 2.5, P = 0.008) in high-catastrophizing and in low-catastrophizing groups, respectively. Adjusted pain during labor, postpartum pain and opioid analgesic use were not significantly different. High-catastrophizers reported less comfort, ability to mobilize and less control during hospitalization. Post-discharge there were no differences in pain or analgesic use.

CONCLUSION

We did not observe greater labor or post-delivery pain or increased analgesic use in high-catastrophizing parturients. High catastrophizers reported greater pain when requesting analgesia, which is consistent with the role of catastrophizing in intensifying the experience of pain.

Investigating the association factors of acute postpartum pain: a cohort study

BACKGROUND

Labor pain intensity is known to predict persistent postpartum pain, whereas acute postpartum pain may interfere with maternal postpartum physical, mental, and emotional well-being. Nevertheless, there is little research studying the association between labor pain intensity and acute postpartum pain. This study investigated the associations between labor pain intensity and psychological factors with acute postpartum pain.

METHODS

We included women with American Society of Anesthesiologists (ASA) physical status II, having ≥ 36 gestational weeks and a singleton pregnancy. We investigated the association between labor pain intensity (primary exposure) and high acute postpartum pain at 0 to 24 h after delivery (Numeric Rating Scale (NRS) ≥ 3 of 10; primary outcome). Pre-delivery questionnaires including Angle Labor Pain Questionnaire (A-LPQ), Pain Catastrophizing Scale (PCS), Fear Avoidance Components Scale (FACS) and State Trait Anxiety Inventory (STAI) were administered. Demographic, pain, obstetric and neonatal characteristics were also collected accordingly.

RESULTS

Of the 880 women studied, 121 (13.8%) had high acute postpartum pain at 0 to 24 h after delivery. A-LPQ total, PCS, FACS and STAI scores were not significantly associated with acute postpartum pain. Greater A-LPQ subscale on birthing pain (adjusted odds ratio (aOR) 1.03, 95% CI 1.01-1.05, p = 0.0008), increased blood loss during delivery (for every 10ml change; aOR 1.01, 95% CI 1.00-1.03, p = 0.0148), presence of shoulder dystocia (aOR 10.06, 95% CI 2.28-44.36, p = 0.0023), and use of pethidine for labor analgesia (aOR 1.74, 95% CI 1.07-2.84, p = 0.0271) were independently associated with high acute postpartum pain. "Sometimes" having nausea during menstruation before current pregnancy (aOR 0.34, 95% CI 0.16-0.72, p = 0.0045) was found to be independently associated with reduced risk of high acute postpartum pain.

CONCLUSIONS

Pre-delivery pain factor together with obstetric complications (shoulder dystocia, blood loss during delivery) were independently associated with high acute postpartum pain.

Factors associated with women's preferences for labor epidural analgesia in Singapore: a survey approach

Epidural analgesia provides effective pain relief during labor. However, there is limited information on the factors associated with pregnant women’s preferences for labor epidural analgesia (LEA) prior to labor onset. We performed a secondary analysis of a clinical trial to identify demographic characteristics, pain and psychological vulnerability factors associated with preferences for LEA. Pregnant women at ≥ 36 weeks’ gestation prior to labor and delivery were recruited and given questionnaires on their LEA preferences, psychological and pain vulnerabilities. The primary outcome was the association between pre-delivery Edinburgh Postnatal Depression Scale (EPDS) with cut-off ≥ 10 and LEA preference. Of the 250 women recruited, 51.6% (n = 129) indicated “yes to LEA”. Amongst those considering LEA as an option to reduce labor pain, women who preferred to use LEA (n = 129) indicated favorable or neutral opinion. Additionally, 68% (n = 82) from those “no to LEA” or “not sure about LEA” still gave either favorable or neutral opinion for LEA (p < 0.0001). The multivariate logistic regression analysis found that EPDS ≥ 10 (p < 0.01), occupation (p = 0.03), ethnicity (p < 0.01), state anxiety (p = 0.02), mode of current pregnancy (unplanned; planned, assisted; planned, natural; p = 0.03) and premenstrual anger/irritability before current pregnancy (p = 0.02) were associated with LEA preference. The findings may help to define the population that may require further education on considering LEA and allow early identification on different LEA preferences to provide patient centric care prior to labor and delivery.

Association of Pain Catastrophizing and Depressive States with Multidimensional Early Labor Pain Assessment in Nulliparous Women Having Epidural Analgesia - A Secondary Analysis

Background

Labor pain is a variable and complex experience with both sensory and affective components. Pain catastrophizing tendencies are predictive of increased distress during labor. Likewise, pain severity has important associations with increased depressive symptoms in mothers, with consequences on perinatal and infant outcomes. Hence, we investigated the association between increased early labor pain with both pre-delivery pain catastrophizing and depressive states.

Methods

We recruited nulliparous women who had requested labor epidural analgesia. Pre-delivery questionnaires including short-form McGill pain questionnaire–2 (SF-MPQ-2), pain catastrophizing scale (PCS), and Edinburgh postnatal depression score (EPDS) were administered.

Results

A total of 712 women completed the pre-delivery questionnaires. There was a significant association between SF-MPQ-2 neuropathic subscale and EPDS ≥ 10 (unadjusted OR 1.74, 95% CI 1.11–2.73, p = 0.0161), as well as PCS ≥ 25 (unadjusted OR 1.55, 95% CI 1.06–2.26, p = 0.0244). SF-MPQ-2 sensory intermittent subscale and EPDS ≥ 10 (unadjusted OR 2.02, 95% CI 1.34–3.03, p = 0.0007), and PCS ≥ 25 (unadjusted OR 1.59, 95% CI 1.14–2.23, p = 0.0069) also showed significant association.

Conclusion

Increased sensory intermittent and neuropathic subsets of early labor pain are significantly correlated with increased pre-delivery pain catastrophizing and depressive states in nulliparous women. This positive association may be useful for pre-delivery risk stratification for early interventions towards a more holistic care management.

Perceived stress during labor and its association with depressive symptomatology, anxiety, and pain catastrophizing

Perceived stress is a dimension of the maternal stress response, however little data is available on perceived stress levels and its associated psychological risk factors during labor. In this secondary data analysis from a prospective study evaluating epidural regimens, we investigated the potential associations between depressive symptomatology, anxiety, and pain catastrophizing with perceived stress during labor. Healthy nulliparous adult women with term singleton pregnancies requesting for epidural analgesia in early labor were included. Assessments were administered after epidural analgesia and adequate pain relief were achieved. Perceived stress (Perceived Stress Scale, PSS, high PSS ≥ 16), depressive symptomatology (Edinburgh Postnatal Depression Scale, EPDS, high EPDS ≥ 10), and pain catastrophizing (Pain Catastrophizing Scale, PCS, high total PCS ≥ 25) were assessed as categorical variables. Additionally, anxiety (State-trait Anxiety Inventory, STAI), PCS total and its subscales (rumination, magnification and helplessness) were analyzed as continuous variables. Univariate and multivariable logistic regression models were used to identify factors associated with high PSS. Of 801 women included, 411 (51.9%) had high PSS. High EPDS (OR 2.16, 95%CI 1.36–3.44), increasing trait anxiety (OR 1.17, 95%CI 1.14–1.20), and increasing pain magnification (OR 1.12, 95%CI 1.05–1.19) were independently associated with high PSS. Depressive symptomatology, trait anxiety, and pain magnification were associated with perceived stress during labor, providing impetus for future research aimed at detecting and alleviating stress and its psychological or pain association factors.

Association of Childbirth Pain with Postnatal Depressive and Anxiety Disorders in Nulliparous Parturients: A Prospective Study

PURPOSE

There is limited knowledge on the relationship between postnatal depression and childbirth pain characteristics associated with childbirth. We investigated whether the characteristics of childbirth pain, as assessed by Short-form-McGill Pain Questionnaire-2 (SF-MPQ-2), were associated with postnatal anxiety and depressive disorders.

PATIENTS AND METHODS

Nulliparous parturients who received labor epidural analgesia (LEA) and delivered in our institution were invited to have a Mini-International Neuropsychiatric Interview (MINI) assessment following their 5-9 weeks post-delivery follow-up phone survey of a larger study. Parturients' demographics, pre-delivery questionnaires on pain and psychological vulnerabilities, LEA data, maternal and neonatal outcomes, postnatal follow-up survey on pain and psychological vulnerabilities, pain and breastfeeding were collected accordingly. The primary outcome was the binary variable (yes/no) of the presence of postnatal depression and/or anxiety disorders based on the post-delivery MINI assessment.

RESULTS

Among the 107 parturients who participated in the post-delivery MINI assessment, a total of 40 (42.5%) patients were found to have postnatal anxiety and depressive disorders. A greater pre-delivery SF-MPQ-2 neuropathic pain mean subscale score (adjusted odds ratio (OR) 1.32, 95% CI 1.00-1.73, p=0.0482) and greater post-delivery Edinburgh Postnatal Depression Scale (EPDS) at 5-9 weeks post-delivery (adjusted OR 1.30, 95% CI 1.13-1.50, p=0.0002) were independently associated with the presence of postnatal anxiety and/or depressive disorders (receiver operating characteristic (ROC) = 0.7489).

CONCLUSION

Patients with greater pre-delivery neuropathic pain and higher EPDS scores at 5-9 weeks post-delivery are more likely to have postnatal depression and/or anxiety disorders, suggesting possible associations between pain and psychological vulnerability in the development of postnatal mental disorders.
