Upper back, neck, and shoulder pain during labor epidural analgesia: a quality improvement initiative.

BACKGROUND: Severe upper back/interscapular, neck and shoulder pain during labor epidural analgesia (PLEA) is not uncommon. The objective of this quality initiative was to evaluate the incidence, demographic associations and management of PLEA. METHODS: An eight-month, single-center quality improvement initiative was performed for the detection and management of PLEA. After survey-based consensus among obstetric anaesthetist attendings and fellows, a three-step PLEA treatment protocol with interventions and numeric rating scale (NRS, 0 - 10 scale) pain assessments was introduced. Demographic data and outcomes were compared among parturients with and without PLEA. RESULTS: Among 2888 women who received labor epidural analgesia from October 2022 through May 2023, 36 (1.2% [95% CI 0.9% to 1.7%]) reported PLEA. Women with PLEA were younger, more likely to be nulliparous, and had a higher body mass index (BMI) than women without PLEA (p < 0.05 for all). A total of 72.2% (26/36) of women with PLEA received at least one protocol treatment. Twenty-three women received first-line therapy, with pain relief in 91.3% (21/23). The median NRS score decreased from 9 [IQR 8-10] to 3 [1-4]. Women with PLEA had a higher incidence of cesarean delivery (CD) and a longer interval between epidural placement and delivery; 52.8 vs. 17.5% (p < 0.001) and 16.5 vs. 6.9 hours (p < 0.001), respectively. CONCLUSIONS: The incidence of PLEA was higher than previously reported. Patients with PLEA were younger, more commonly nulliparous, had higher BMI, longer epidural infusion times and higher CD rates. A three-step treatment protocol was successful in managing PLEA.

The effectiveness and outcomes of epidural analgesia in patients undergoing open liver resection: a propensity score matching analysis.

BACKGROUND: Open liver resection necessitates a substantial upper abdominal inverted-L incision, resulting in severe pain and compromising patient recovery. Despite the efficacy of epidural analgesia in providing adequate postoperative analgesia, the potential epidural-related adverse effects should be carefully considered. This study aims to compare the efficacy and safety of continuous epidural analgesia and intravenous analgesia in open liver resection. METHODS: A retrospective study was conducted, collecting data from patients who underwent open liver resection between 2007 and 2017. Propensity score matching was implemented to mitigate confounding variables, with patients being matched in a 1:1 ratio based on propensity scores. The primary outcome was the comparison of postoperative morphine consumption at 24, 48, and 72 hours between the two groups. Secondary outcomes included pain scores, postoperative outcomes, and epidural-related adverse effects. RESULTS: A total of 612 patients were included, and after matching, there were 204 patients in each group. Opioid consumption at 24, 48, and 72 hours postoperatively was statistically lower in the epidural analgesia group compared to the intravenous analgesia group (p < 0.001). However, there was no significant difference in pain scores (p = 0.422). Additionally, perioperative hypotension requiring treatment, as well as nausea and vomiting, were significantly higher in the epidural analgesia group compared to the intravenous analgesia group (p < 0.001). CONCLUSIONS: Epidural analgesia is superior to intravenous morphine in terms of reducing postoperative opioid consumption within the initial 72 h after open liver resection. Nevertheless, perioperative hypotension, which necessitates management, should be approached with consideration and vigilance. TRIAL REGISTRATION: The study was registered in the Clinical Trials Registry at www. CLINICALTRIALS: gov/ , NCT number: NCT06301932.

Predictive value of neutrophil-to-lymphocyte ratio on admission for intrapartum maternal fever in parturients undergoing epidural analgesia: A retrospective cohort study using propensity score-matched analysis.

OBJECTIVE: To identify the predictive value of the neutrophil-to-lymphocyte ratio (NLR) on admission for intrapartum maternal fever in parturients undergoing epidural analgesia (EA). METHODS: In this retrospective cohort study, propensity score matching (PSM) was applied to address covariates. Univariate and multivariate regression analyses were implemented in sequence to find out the factors influencing intrapartum fever. The receiver operating characteristics curve was applied to determine the area under the curve (AUC) of NLR for intrapartum fever. RESULTS: NLR and duration of EA were independent risk factors for intrapartum fever. The AUC of the combined indicator (NLR + duration of EA) was higher than that of NLR (AUC = 0.583, 95% confidence interval [CI] 0.53-0.64) and duration of EA (AUC = 0.702, 95% CI 0.66-0.75), reaching 0.715 (95% CI 0.67-0.76; p < 0.001). NLR increased predictive performance for intrapartum fever when added to the duration of EA (net reclassification index 0.076, p = 0.022; integrated discrimination improvement 0.020, p = 0.002). CONCLUSION: NLR has limited predictive power for intrapartum fever. The combination of NLR and duration of epidural analgesia may be considered a promising predictor for intrapartum maternal fever in parturients undergoing epidural analgesia. SYNOPSIS: The neutrophil-to-lymphocyte ratio is an accessible predictor for the early identification of parturients at risk of intrapartum fever.

Unintentional Infusion of Insulin Into the Epidural Space During Labor.

Inadvertent injection of drugs into the epidural space has a potential for serious morbidity and is probably underestimated and underreported. A 39-year-old female with no medical history presented for delivery. An epidural catheter was requested and correctly placed. Continuous epidural infusion was chosen for labor analgesia. Six hours after the parturient complained about inefficient analgesia, a syringe swap with insulin was identified. Despite the risk of possibly neurotoxic preservatives in the insulin formulation, no neurological sequelae were observed. This case highlights the issue of wrong-route drug administration and the urgent need to adopt route-specific connections.

Morphological and morphometric analysis of the Sacral Hiatus using lumbosacral spine CT scans: clinical relevance in Caudal Epidural Analgesia.

BACKGROUND: To conduct a morphological and morphometric analysis of the sacral hiatus (SH) using lumbosacral spine CT scans and to evaluate its clinical relevance in caudal epidural analgesia (CEA). MATERIALS AND METHODS: This retrospective study analyzed 77 lumbosacral spine CT scans from a diverse patient population. The shape of the SH was classified into common types: inverted U, inverted V, irregular, and bilobed. Morphometric measurements included the length, width, and depth at the apex of the SH. The apex level of the SH was also determined in relation to the sacral vertebrae, and statistical analysis was performed to identify any correlation between the apex level and the morphometric dimensions. RESULTS: The most frequent SH shape was inverted U (68.83%), followed by inverted V (20.77%), irregular (9%), and a single instance of a bilobed shape (1.29%). The apex of the SH was most commonly located at the level of the S4 vertebra (75.32%), followed by the S3 vertebra (20.77%), S5 in two (2.59) and S2 in one (1.29%). No significant correlation was found between the level of the apex and the length, width, or depth of the SH. These findings indicate a high degree of anatomical variability in the SH, independent of the apex level. CONCLUSIONS: The anatomical variability of the SH, as observed in this study, underscores the need for individualized assessment during CEA. The lack of correlation between the apex level and the morphometric dimensions of the SH highlights the importance of imaging modalities such as ultrasound or fluoroscopy to ensure precise localization and effective analgesia administration. These insights can improve clinical outcomes by enhancing the accuracy and safety of caudal epidural procedures.

Risk factors for postoperative urinary retention in patients underwent surgery for benign anorectal diseases: a nested case-control study.

BACKGROUND: Postoperative urinary retention (POUR) is a common complication of anorectal surgery. This study was to determine the incidence of POUR in anorectal surgery for benign anorectal diseases, identify its risk factors, and establish a nomogram for prediction of POUR. METHODS: A nested case-control study was conducted. The clinical data of patients were collected, and the incidence of POUR was analyzed. Univariate analysis was used to identify the risk factors associated with POUR, and multivariate logistic regression analysis was used to determine independent risk factors for POUR. A nomogram for the preoperative prediction of POUR using a logistic regression model was developed (n = 609). RESULTS: The incidence of POUR after anorectal surgery for benign anorectal diseases was 19.05%. The independent risk factors for POUR were: female (P = 0.007); male with benign prostatic hyperplasia (BPH) (P = 0.001); postoperative visual analogue scale (VAS) score > 6 (P = 0.002); patient-controlled epidural analgesia (PCEA) (P = 0.016); and a surgery time > 30 min (P = 0.039). In the nomogram, BPH is the most important factor affecting the occurrence of POUR, followed by a postoperative VAS score > 6, PCEA, surgery time > 30 min, and sex has the least influence. CONCLUSION: For patients undergoing anorectal surgery for benign anorectal diseases, preventive measures can be taken to reduce the risk of POUR, taking into account the following risk factors: female or male with BPH, severe postoperative pain, PCEA, and surgery time > 30 min. Furthermore, we developed and validated an easy-to-use nomogram for preoperative prediction of POUR in anorectal surgery for benign anorectal diseases.

Association between neutrophil-to-lymphocyte ratio and epidural-related maternal fever in Chinese parturients: a prospective cohort study.

OBJECTIVE: Epidural analgesia could increase the risk of maternal fever during labor, and the potential mechanisms involved inflammation. Neutrophil-to-lymphocyte ratio (NLR) was a sensitive inflammatory composite indicator and related to adverse outcomes in parturients. This study aimed to investigate the association between NLR levels and epidural related maternal fever (ERMF). METHODS: This prospective cohort study included 614 parturients who underwent epidural analgesia at the Women's Hospital School of Medicine Zhejiang University from November 2021 to May 2023. NLR level was calculated before epidural analgesia for women. The outcome was ERMF. Univariate and multivariate logistic regression models were utilized to explore the association between NLR level and ERMF. And the association was further investigated in subgroups of age, body mass index (BMI) before pregnancy, and parity of delivery. The results were presented as odds ratios (ORs) and 95% confidence intervals (CIs). RESULTS: Totally, 614 parturients, of whom 171 (27.85%) had ERMF. High NLR level was associated with higher incidence of ERMF (OR = 2.70, 95% CI: 1.58-4.69). Parturients with ERMF had higher proportion of postpartum hemorrhage, longer labor times, and other adverse outcomes in parturients. The association also observed in subgroups of age <35 years old (OR = 2.74, 95% CI: 1.55-4.29), BMI <24 kg/m2 before pregnancy (OR = 2.32, 95% CI: 1.32-4.13), BMI ≥24 kg/m2 before pregnancy (OR = 38.28, 95%CI: 3.67-854.66), primipara (OR = 2.26, 95% CI:1.27-4.04), and multipara (OR = 30.60, 95% CI: 3.73-734.03). CONCLUSION: High NLR levels were associated with ERMF in women. It indicated that physicians may measure NLR levels as a regular measurement, which may beneficial for pregnancy outcomes.

Risk factors for postpartum urinary retention: An updated systematic review and meta-analysis.

BACKGROUND: There are conflicting reports on the factors that increase the likelihood of postpartum urinary retention (PUR). OBJECTIVES: We completed an updated systematic review and meta-analysis to identify the risk factors for PUR. SEARCH STRATEGY: An exhaustive search of the literature was undertaken using multiple databases, including PubMed, Web of Science, the Cochrane Library, and Embase to identify pertinent studies published up until November 4, 2023. SELECTION CRITERIA: Observational studies that provided outcomes to calculate the risk factors for PUR were included. DATA COLLECTION AND ANALYSIS: Two investigators separately performed the extraction of pertinent data from the articles. The risk factors for PUR were identified by pooling adjusted and unadjusted odds ratios (ORs) and 95% confidence intervals (CIs). Heterogeneity test, sensitivity analysis, and publication bias assessment were performed. MAIN RESULTS: This meta-analysis included 21 studies with a total of 36 951 participants. Meta-analysis was performed for 14 risk factors, and eight of these were statistically significant. The risk factors that were identified in this review included instrumental delivery (OR, 2.96 [95% CI, 1.82-4.80]; 95% prediction interval [PI], 0.67-12.98), relatively long duration of labor (OR, 1.04 [95% CI, 1.02-1.06]; 95% PI, 1.00-1.08), episiotomy (OR, 1.56 [95% CI, 1.19-2.06] 95% PI, 0.64-3.83), nulliparity (OR, 1.55 [95% CI, 1.30-1.84]; 95% PI, 0.94-2.77), epidural analgesia (OR, 2.99 [95% CI, 1.78-5.03]; 95% PI, 0.53-16.76), labor augmentation (OR, 2.21 [95% CI, 1.49-3.28]; 95% PI, 0.12-39.26), labor induction (OR, 1.73 [95% CI, 1.12-2.66]; 95% PI, 0.40-7.39), and perineal injury (OR, 2.75 [95% CI, 1.95-3.89]; 95% PI, 1.10-6.92). CONCLUSION: Instrumental delivery, extended labor duration, episiotomy, nulliparity, epidural analgesia, labor augmentation/induction, and perineal injury are significant risk factors for PUR. The findings could help physicians identify patients at risk in the postpartum setting.

Comparison of patient-controlled epidural analgesia and epidural morphine for post-cesarean section analgesia: experience from a tertiary center in China.

PURPOSE: To compare patient-controlled epidural analgesia (PCEA) and epidural morphine (EM) for post-cesarean section analgesia in real-world experience from China. METHODS: Parturients receiving one dose of EM (1-2 mg), PCEA, or both EM and PCEA from Peking Union Medical College Hospital were retrospectively recruited. Logistic models were used to identify risk factors. RESULTS: Of 1079 parturients enrolled, 919 (85.2%) parturients received only EM, 105 (9.7%) parturients received PCEA, and 55 (5.1%) parturients received both EM and PCEA. Significantly more parturients from EM group requested supplementary analgesia than those from PCEA and PCEA + EM group (583, 63.4% vs 52, 49.5% vs 25, 45.5%, P = 0.001) with more times of supplementary analgesia (1, IQR: 0-2 vs 0, IQR: 0-1 vs 0, IQR: 0-1 times, P < 0.001) and larger amounts of nonsteroidal anti-inflammatory drugs (NSAIDs) (50, IQR: 0-100 mg vs 0, IQR: 0-50 mg vs 0, IQR: 0-50 mg, P < 0.001). In multivariable Logistic regression for the supplementary analgesia risk, the application of PCEA (OR: 0.557, 95%CI 0.396-0.783, P = 0.001) and the use of NSAIDs intraoperatively (OR: 2.996, 95%CI 1.811-4.957, P < 0.001) were identified as independent predictors. A total of 1040 (96.4%) patients received prophylactic antiemetic therapy during surgery. Only 13 (1.2%) and 7 (0.6%) patients in our cohort requested antiemetic and antipruritic drugs, respectively. CONCLUSION: The use of PCEA was an independent protective factor for supplementary analgesia during the post-cesarean section. Prophylactic antiemetic therapy may reduce the side effects of post-cesarean analgesia.

Sacral sensory blockade from 27-gauge pencil-point dural puncture epidural analgesia or epidural analgesia in laboring nulliparous parturients: a randomized controlled trial.

BACKGROUND: The dural puncture epidural (DPE) technique has been associated with better sacral analgesia compared with a traditional epidural (EPL) technique in laboring parturients. The aim of this study was to investigate whether DPE with a 27-gauge pencil-point needle compared with a traditional EPL technique produces more rapid bilateral sacral blockade in nulliparous parturients. METHODS: Patients were randomized to a DPE or EPL technique. Epidural analgesia in both groups was initiated with ropivacaine 0.1% and sufentanil 0.5 µg/mL (15 mL) and maintained via programmed intermittent epidural boluses. Analgesic blockade was tested bilaterally beginning 10 min after initiation, and then at predefined intervals until delivery. The presence of an S2 blockade at 20 min was the primary outcome. RESULTS: Among 108 (54 per group) patients enrolled, bilateral sacral (S2) blockade at 20 min was significantly more common in the DPE than in the EPL group [47 (87%) vs. 23 (43%), absolute risk reduction (ARR) 44%, 95% CI 28 to 60; P < 0.001]. Time to a numeric pain rating scale score (0-10 scale) ≤ 3 (20 [20,30] min in both groups, HR 1.15, 95% CI 0.77 to 1.15; P = 0.50), number of rescue doses [0 (0, 1) vs 0 (0, 1); P 0.08], and presence of bilateral S2 blockade at delivery were not significantly different between groups. CONCLUSIONS: The DPE technique with a 27-gauge pencil-point spinal needle more often provides bilateral sacral blockade at 20 min following block initiation compared with the EPL technique. The time to adequate analgesia and need for supplemental analgesia did not appear to differ between techniques.

Application of dezocine patient-controlled epidural analgesia in postoperative analgesia in patients with total myomectomy.

BACKGROUND: Uterine fibroids are common benign gynecological conditions. Patients who experience excessive menstruation, anemia, and pressure symptoms should be administered medication, and severe cases require a total hysterectomy. This procedure is invasive and causes severe postoperative pain, which can affect the patient's postoperative sleep quality and, thus, the recovery process. AIM: To evaluate use of dezocine in patient-controlled epidural analgesia (PCEA) for postoperative pain management in patients undergoing total myomectomy. METHODS: We selected 100 patients undergoing total abdominal hysterectomy for uterine fibroids and randomized them into two groups: A control group receiving 0.2% ropivacaine plus 0.06 mg/mL of morphine and an observation group receiving 0.2% ropivacaine plus 0.3 mg/mL of diazoxide in their PCEA. Outcomes assessed included pain levels, sedation, recovery indices, PCEA usage, stress factors, and sleep quality. RESULTS: The observation group showed lower visual analog scale scores, shorter postoperative recovery indices, fewer mean PCEA compressions, lower cortisol and blood glucose levels, and better polysomnographic parameters compared to the control group (P < 0.05). The cumulative incidence of adverse reactions was lower in the observation group than in the control group (P < 0.05). CONCLUSION: Dezocine PCEA can effectively control the pain associated with total myomectomy, reduce the negative impact of stress factors, and have less impact on patients' sleep, consequently resulting in fewer adverse effects.

Effects of epidural analgesia at 1 cm cervical dilatation on multiparae: A retrospective cohort study using propensity score-matching.

OBJECTIVE: The aim of the present study was to investigate the effects of epidural analgesia (EA) administered at cervical dilatation of 1 cm on multiparae who underwent vaginal delivery. METHODS: This propensity score-matched retrospective cohort research was conducted between 2021 and 2022. All the singleton multiparae who had previous successful vaginal deliveries and epidural analgesia during this delivery were screened for eligibility. The primary outcome was the effect of EA on the duration of labor. The main secondary outcomes included the incidence of cesarean delivery and umbilical arterial pH. RESULTS: This study incorporated 686 multiparae who were divided into two cohorts: EA 1 (cervical dilatation = 1 cm, n = 166) and EA 2 (cervical dilatation >1 cm, n = 520). In the propensity score-matched cohort (including 164 women in each group), there were no statistically significant differences in the incidence of cesarean delivery (4 [2.4%] vs 4 [2.4%], P = 1.000), umbilical arterial pH (7.28 ± 0.06 vs 7.28 ± 0.07, P = 0.550) and other secondary outcomes between the two groups. Based on a comparative assessment of the women who delivered vaginally to the Kaplan-Meier curves and propensity score-matching (including 160 women in each group), there was no statistical significance in the duration of the first, second and third stages of labor (log rank P, P = 0.811; P = 0.413; P = 0.773, respectively). CONCLUSION: Initiation of epidural analgesia at cervical dilatation of 1 cm in multiparae did not cause adverse effects with regard to the duration of labor, increased cesarean deliveries, and bad neonatal outcomes.

Combined impact of local anaesthetic infiltration through wound catheter and epidural analgesia following surgical hepatectomy: a meta-analysis.

Introduction: A meta-analysis was performed to examine the effects of wound catheter (WC) local anaesthetic infiltration (LAI) and epidural analgesia (EA) in open hepatectomy (OH). Material and methods: A systematic literature review was performed, which found 350 subjects with OH at the baseline of the studies; 159 of them were treated with WC local anaesthetic infiltration, and 191 used EA. Results: WC LAI substantially reduced the functional recovery time (MD = -0.64; 95% CI, -1.02 to -0.26, p < 0.001) and increased the pain score on the second postoperative day (MD = 0.25; 95% CI: 0.10-0.40, p < 0.001) compared to EA in OH patients. WC LAI did not vary from EA in OH patients in second postoperative opiate use (MD = -14.86; 95% CI: -32.88 to 3.16, p = 0.11) or overall complication rate (OR = 0.66; 95% CI: 0.41-1.04, p = 0.07). Conclusions: WC LAI showed a non-significant difference in opiate consumption on the second postoperative day and in the overall complication rate, compared with EA, but it showed a lower functional recovery time and higher pain score.

Epidural analgesia during surgery and its relation to postoperative myocardial infarction: meta-analysis.

Introduction: Epidural analgesia has been studied for its potential advantages after surgery in a number of randomized clinical trials, with most finding improvements in pain and secondary endpoints like the incidence of postoperative complications. Aim: To assess the relationship between use of epidural analgesia and adverse cardiac outcomes expressed by myocardial infarction (MI). Material and methods: Fifty-three studies were recruited to quantify the influence of different surgical-related analgesic methods on clinical parameters (mortality and adverse events). The results of these trials were analysed using a random effects model, which was then used to calculate the mean difference (MD) with 95 per cent confidence intervals (CIs). Results: Epidural analgesia resulted in preferred cardiac outcomes compared with traditional analgesia. These findings were supported by significantly lower MI events for the epidural analgesia group as follows: p = 0.005, p = 0,007, and p = 0.03 for the total number of included studies, studies with high risk of bias, and studies with low risk of bias, respectively. Studies with intermediate risk showed a non-significant difference between both groups (p = 0.7). Conclusions: Epidural analgesia has a significant protective cardiac effect through the reduction of postoperative MI events among surgery subjects.

Variations in the use of oxytocin for augmentation of labour in Sweden: a population-based cohort study.

National Swedish data shows substantial variation in the use of oxytocin for augmentation of spontaneous labour between obstetric units. This study aimed to investigate if variations in the use of oxytocin augmentation are associated with maternal and infant characteristics or clinical factors. We used a cohort design including women allocated to Robson group 1 (nulliparous women, gestational week ≥ 37 + 0, with singleton births in cephalic presentation and spontaneous onset of labour) and 3 (parous women, gestational week ≥ 37 + 0, with singleton births in cephalic presentation, spontaneous onset of labour, and no previous caesarean birth). Crude and adjusted logistic regression models with marginal standardisation were used to estimate risk ratios (RR) and risk differences (RD) with 95% confidence intervals (CI) for oxytocin use by obstetric unit. An interaction analysis was performed to investigate the potential modifying effect of epidural. The use of oxytocin varied between 47 and 73% in Robson group 1, and 10% and 33% in Robson group 3. Compared to the remainder of Sweden, the risk of oxytocin augmentation ranged from 13% lower (RD - 13.0, 95% CI - 15.5 to - 10.6) to 14% higher (RD 14.0, 95% CI 12.3-15.8) in Robson group 1, and from 6% lower (RD - 5.6, 95% CI - 6.8 to - 4.5) to 18% higher (RD 17.9, 95% CI 16.5-19.4) in Robson group 3. The most notable differences in risk estimates were observed among women in Robson group 3 with epidural. In conclusion, variations in oxytocin use remained despite adjusting for risk factors. This indicates unjustified differences in use of oxytocin in clinical practice.

Programmed Intermittent Epidural Bolus Reduces Workloads in Labor Analgesia: A Single Center's Experience.

Background and Objectives: Labor epidural analgesia can be maintained through programmed intermittent epidural bolus (PIEB), continuous epidural infusion (CEI), or patient-controlled epidural analgesia (PCEA). Our department changed from CEI+PCEA to PIEB+PCEA as the maintenance method. The higher hourly dose setting in the current regimen brought to our concern that side effects would increase with proportional staff workloads. This study aimed to investigate the validity of our proposal that PIEB+PCEA may function as a feasible tool in reducing the amount of work in the obstetrics anesthesia units. Materials and methods: This 2-year retrospective review included parturients with vaginal deliveries under epidural analgesia. We compared the staff burden before and after the switch from CEI (6 mL/h, PCEA 6 mL lockout 15 min, group A) to PIEB (8 mL/h, PCEA 8 mL lockout 10 min, group B). The primary outcome was the difference of proportion of parturients requiring unscheduled visits between groups. Side effects and labor and neonatal outcomes were compared. Results: Of the 694 parturients analyzed, the proportion of those requiring unscheduled visits were significantly reduced in group B (20.8% vs. 27.7%, chi-square test, p = 0.033). The multivariate logistic regression showed that PIEB was associated with fewer unscheduled visits than CEI (OR = 0.53, 95% CI [0.36-0.80], p < 0.01). Group B exhibited a significantly lower incidence of asymmetric blockade, as well as motor blockade. In nulliparous subjects, obstetric anal sphincter injury occurred less frequently when PIEB+PCEA was used. Significantly more multiparous women experienced vacuum extraction delivery in group B than in group A, and they had a longer second stage of labor. Conclusions: The PIEB+PCEA protocol in our study reduced workloads in labor epidural analgesia as compared to CEI+PCEA, despite that a higher dose of analgesics was administered. Future studies are warranted to investigate the effect of manipulating the PIEB settings on the labor outcomes.

Regional anesthesia in a patient with primary ciliary dyskinesia: A case report.

BACKGROUND: Primary ciliary dyskinesia (PCD) is an inherited autosomal-recessive disorder of impaired mucociliary clearance characterized by chronic respiratory diseases, otolaryngological diseases, central nervous system abnormalities, reproductive system abnormalities, and cardiac function abnormalities. General anesthesia in these patients is associated with a higher incidence of respiratory complications than in patients without the disease. CASE SUMMARY: A 16-year-old male patient was referred to the emergency room complaining of right ankle pain due to distal tibiofibular fracture. Three years prior, he had been diagnosed with PCD. At that time, he had experienced several episodes of pneumonia, sinusitis, and chronic middle ear infections, for which he underwent surgical interventions. At the current admission, he presented with cough and sputum but no other respiratory symptoms. A chest computed tomography scan revealed centrilobular ground-glass opacities in both lower lobes and a calcified nodule in the left lower lobe. For the surgical procedure and postoperative pain management, combined spinal-epidural anesthesia was employed. The patient's postoperative pain score was measured by the numerical rating scale (NRS). On the day of surgery, his NRS was 5 points. By the second postoperative day, the NRS score had decreased to 2-3 points. The epidural catheter was removed on the fourth day following the operation. The patient was subsequently discharged no respiratory complications. CONCLUSION: We performed combined spinal-epidural anesthesia in a patient with PCD. The patient experienced no additional respiratory complications and was discharged with a low NRS score for pain.

Epidural analgesia in labour: separating fact from fiction for autism and neurodevelopment.

Having epidural analgesia in labour has been associated with a later diagnosis of autism spectrum disorder in the offspring, resulting in concerns about childhood wellbeing. Neurodevelopmental changes are inconsistently reported in the literature, creating challenges in the interpretation of these findings. Here we explore the limitations of the current evidence base, and why findings differ between studies, concluding that the current body of evidence does not support a causal association between use of epidural analgesia in labour and autism spectrum disorder.
