Maximum Pain at Rest in Pediatric Patients Undergoing Elective Thoracic Surgery and the Predictors of Moderate-to-Severe Pain-Secondary Data Analysis

INTRODUCTION

Pain management among children following thoracic surgery is an area of significant practice variability. Understanding the risk factors of moderate-to-severe pain intensity will allow for adequate pain relief. The aim of the study was to assess the maximum intensity of pain at rest in pediatric patients within 24 h of thoracic surgery and to investigate the prevalence and predictors of moderate-to-severe pain.

METHODS AND FINDINGS

This is a prospective cohort study of patients in observational and randomized controlled trials following thoracic surgery. A secondary analysis of data was conducted using data collected from 446 patients aged 7-18 years undergoing thoracic surgery. The primary endpoint was maximum pain intensity (Numerical Rating Scale; NRS; range: 0-10) and the secondary endpoint was the prevalence and predictors of moderate-to-severe pain (NRS > 2/10). The median maximum pain in the cohort was 3 [0; 4]. During the immediate postoperative period, 54% of patients reported a maximum NRS > 2/10. The infusion of morphine by an intravenous route (vs. epidural route) was a protective factor against moderate-to-severe pain. Taking into account the findings related to the type of epidural analgesia (vs. intravenous morphine), it was found that only the administration of 0.25% bupivacaine combined with morphine or fentanyl was a protective factor against moderate-to-severe postoperative pain. Patients aged 14-18 years (vs. aged 7-13 years) had an increased risk of reporting pain as moderate-to-severe.

CONCLUSIONS

The route of analgesic administration, type of multimodal analgesia, and patients' age predict moderate-to-severe pain in pediatric patients after thoracic surgery.

Minimally invasive repair of pectus excavatum in adults: a review article of presentation, workup, and surgical treatment

Pectus excavatum (Pex) is one of the most common congenital deformities of the chest wall, with pectus constituting 90% of all chest wall deformities and excavatum being reported in almost 1:400 to 1:1,000 live births with predominant occurrence in males up to five times more than in females. Depending on the severity, presentation varies from mild cosmetic complaints to life limiting cardiopulmonary symptoms. Patients may develop symptoms as they age, and these symptoms may worsen over the years. A technique for minimally invasive repair for pectus excavatum (MIRPE) was introduced with the concept of temporarily implanting metal bars to correct the deformity. This has rapidly become the standard of care for the pediatric and adolescent patients. The use of MIRPE in adults, however, has been slower to adopt and more controversial. This is largely due to the increased calcification and rigidity of the chest wall in adults which can make the repair more complex and lead to a higher risk of complications. We present a literature review of the presentation, workup, and surgical treatment of adult patients with Pex undergoing MIRPE. Adult patients can, with advanced preoperative evaluations and technique modifications, undergo a highly successful repair resulting in symptom resolution and satisfying results.

Factors Related to Anxiety in Paediatric Patients and Their Parents before and after a Modified Ravitch Procedure-A Single-Centre Cohort Study

OBJECTIVE

To assess the factors related to perioperative state anxiety in paediatric patients and their parents.

METHODS

A cohort study was conducted on paediatric patients 9-17 years of age, who underwent the modified Ravitch procedure (n = 96), and their parents (n = 96). The level of anxiety was measured using the State-Trait Anxiety Inventory questionnaire. Multivariable linear regression models were calculated to find the relationships between the pre- and postoperative state anxiety of the patients/parents and the independent variables, both demographic (age, gender) and clinical (e.g., postoperative pain, trait anxiety).

RESULTS

Preoperative anxiety in the paediatric patients was positively correlated with their trait anxiety (β = 0.47; 95% CI: 0.29 to 0.64) and preoperative parental anxiety (β = 0.24; 95% CI: 0.07 to 0.42). The high level of preoperative anxiety (vs. low and moderate) (β = 0.40; 95% CI: 0.22 to 0.58), trait anxiety (β = 0.22; 95% CI: 0.04 to 0.40) and average postoperative pain at rest (β = 0.18; 95% CI: 0.01 to 0.34) had a positive impact on the postoperative anxiety in patients. However, the patients' age was negatively correlated with postoperative anxiety (β = -0.19; 95% CI: -0.35 to -0.02). Three variables were found to predict preoperative parental anxiety: their trait anxiety (β = 0.41; 95% CI: 0.23 to 0.59), female gender (β = 0.18; 95% CI: 0.002 to 0.36) and the intravenous route for the postoperative pain management in the patients (β = -0.18; 95% CI: -0.36 to -0.001). The parental postoperative anxiety was influenced by their trait anxiety (β = 0.24; 95% CI: 0.04 to 0.43), preoperative anxiety in patients (β = 0.21; 95% CI: 0.02 to 0.40) and female gender of children (β = 0.19; 95% CI: 0.001 to 0.39).

CONCLUSIONS

Trait anxiety was a strong factor positively affecting the perioperative state anxiety. In addition, paediatric patient anxiety before surgery was related to their parents' anxiety, and, after surgery, this was associated with high preoperative anxiety, pain and age. The parents' anxiety before surgery was influenced by gender and the type of postoperative analgesia in the patients, while, after surgery, this was influenced by the patients' preoperative anxiety/gender.

Intravenous Morphine Infusion versus Thoracic Epidural Infusion of Ropivacaine with Fentanyl after the Ravitch Procedure-A Single-Center Cohort Study

OBJECTIVE

To compare the efficacy of analgesia with intravenous infusion of morphine and thoracic epidural infusion of ropivacaine with fentanyl in pediatric patients after the Ravitch procedure.

METHODS

Postoperative analgesia was achieved by intravenous morphine infusion with a dose of 0.02-0.06 mg/kg per hour (intravenous group, n = 56) or thoracic epidural infusion of 0.2% ropivacaine and fentanyl 5 µg/mL with a flow rate of 0.1 mL/kg per hour (epidural group, n = 40). Furthermore, the multimodal pain management protocol included paracetamol, non-steroidal anti-inflammatory drugs, and metamizole as a rescue drug. The primary outcomes included pain scores (according to the Numerical Rating Scale, range 0-10), while the secondary outcomes included consumption of the rescue drug, anxiety, postoperative side effects, and patient satisfaction. The observation period lasted from postoperative day 0 to postoperative day 3.

RESULTS

Median average and maximal pain scores at rest, during deep breathing, and coughing were significantly lower in the intravenous group compared to the epidural group (p < 0.05). The effect size was medium (Cohen's d ranged from 0.5 to 0.7). Patients receiving morphine required significantly lower numbers of metamizole doses than in the epidural group (median 1 vs. 3; p = 0.003; Cohen's d = 0.6). Anxiety, postoperative side effects, and patient satisfaction were similar in both groups (p > 0.05).

CONCLUSIONS

An intravenous infusion of morphine may offer better postoperative analgesia than a thoracic epidural infusion of ropivacaine with fentanyl.

The Effects of Gabapentin on Post-Operative Pain and Anxiety, Morphine Consumption and Patient Satisfaction in Paediatric Patients Following the Ravitch Procedure-A Randomised, Double-Blind, Placebo-Controlled, Phase 4 Trial

The aim of the study was to investigate whether the use of pre- and postoperative gabapentin can decrease postoperative pain, morphine consumption, anxiety and side effects, as well as improve patient satisfaction. A total of 56 patients, 9−17 years of age, undergoing a modified Ravitch procedure, were randomised (allocation ratio 1:1) to receive multiple perioperative doses of gabapentin (preoperatively 15 mg/kg, postoperatively 7.5 mg/kg, two times per day for three days) or a placebo. All the patients received intravenous infusion of morphine, paracetamol and non-steroidal anti-inflammatory drugs. Metamizole was given as a “rescue drug”. The observation period included the day of surgery and three postoperative days. The primary outcomes were postoperative pain intensity (at rest, during deep breathing and coughing). Additional outcomes included the consumption of morphine, the total number of doses of metamizole, anxiety, postoperative side effects and patient satisfaction. Median average and maximal pain scores (on the day of surgery and on the second postoperative day) were significantly lower only in the gabapentin group at rest (p < 0.05). Compared to the placebo group, gabapentin treatment reduced the demand for morphine on the first postoperative day (median 0.016 vs. 0.019 mg/kg/h; p = 0.03) and the total number of metamizole doses (median 1 vs. 2 p = 0.04). Patient satisfaction was significantly greater in the gabapentin group (median 10 vs. 9; p = 0.018). Anxiety and postoperative side effects were similar in both groups (p > 0.05). Pre- and postoperative gabapentin administration as part of a multimodal analgesic regimen may decrease postoperative pain, opioid consumption and demand for a “rescue drug”, as well as improve patient satisfaction.
