Association of chronic poststernotomy pain and health-related quality of life: a prospective cohort study.

PURPOSE: Chronic poststernotomy pain (CPSP) after cardiac surgery is multifactorial and impacts patient recovery. We aimed to evaluate the association between CPSP severity and health-related quality of life at six months after cardiac surgery. METHODS: This was a single-centre prospective cohort study of patients who underwent cardiac surgery with median sternotomy between September 2020 and March 2021. Telephone interviews were conducted at six and 12 months postoperatively using the Short Form McGill Pain Questionnaire and the EQ-5D-5L. Strength of correlation was described using Spearman's correlation coefficient. Multivariable regression analysis was used to account for confounding variables. RESULTS: A total of 252 patients responded to the six-month interview (response rate, 65%). The mean (standard deviation) age of respondents was 65 (13) yr. Twenty-nine percent of respondents (72/252) reported CPSP at six months, and 14% (41/252) reported more than mild pain (score ≥ 2/5). At 12 months, of the 89% (64/72) patients who responded, 47% (30/64) still reported pain. The strength of the correlation between pain scores and EQ-5D-5L was weak (Spearman's correlation coefficient, -0.3). Risk factors for CPSP at six months included higher pain score on postoperative day 1, history of chronic pain prior to surgery, and history of depression. Intraoperative infusion of dexmedetomidine or ketamine was associated with a reduced risk of CPSP at six months. CONCLUSION: Chronic poststernotomy pain still affects patient recovery at six and 12 months after cardiac surgery. The severity of that pain is poorly correlated with patients' quality of life.

RéSUMé: OBJECTIF: La douleur chronique post-sternotomie (DCPS) après une chirurgie cardiaque est multifactorielle et a un impact sur le rétablissement des patient·es. Nous avons cherché à évaluer l'association entre la sévérité de la DCPS et la qualité de vie liée à la santé six mois après la chirurgie cardiaque. MéTHODE: Il s'agissait d'une étude de cohorte prospective monocentrique portant sur des patient·es ayant bénéficié d'une chirurgie cardiaque avec sternotomie médiane entre septembre 2020 et mars 2021. Des entrevues téléphoniques ont été menées à six et 12 mois après l'opération en se servant du questionnaire abrégé de McGill sur la douleur et de l'EQ-5D-5L. La force de corrélation a été décrite à l'aide du coefficient de corrélation de Spearman. Une analyse de régression multivariée a été utilisée pour tenir compte des variables confondantes. RéSULTATS: Au total, 252 patient·es ont répondu à l'entrevue à six mois (taux de réponse de 65 %). L'âge moyen (écart type) des répondant·es était de 65 (13) ans. Vingt-neuf pour cent des personnes répondantes (72/252) ont déclaré avoir été atteintes de DCPS à six mois, et 14 % (41/252) ont signalé une douleur plus que légère (score ≥ 2/5). À 12 mois, sur les 89 % (64/72) personnes ayant répondu, 47 % (30/64) signalaient encore de la douleur. La force de la corrélation entre les scores de douleur et l'EQ-5D-5L était faible (coefficient de corrélation de Spearman, −0,3). Les facteurs de risque de DCPS à six mois comprenaient un score de douleur plus élevé au jour 1 postopératoire, des antécédents de douleur chronique avant la chirurgie et des antécédents de dépression. Une perfusion peropératoire de dexmédétomidine ou de kétamine a été associée à une réduction du risque de DCPS à six mois. CONCLUSION: La douleur chronique post-sternotomie affecte toujours le rétablissement des patient·es six et 12 mois après la chirurgie cardiaque. La sévérité de cette douleur est faiblement corrélée à la qualité de vie des patient·es. ENREGISTREMENT DE L'éTUDE: www.osf.io ( https://osf.io/52rsw ); enregistrée le 14 mai 2022.

The analgesic effects of combined bilateral parasternal block and serratus anterior plane block for coronary artery bypass grafting surgery.

BACKGROUND: Severe pain occurs after cardiac surgery in the sternum and chest tubes sites. Although analgesia targeting the sternum is often prioritized, the analgesia of the drain site is sometimes overlooked. This study of patients undergoing coronary artery bypass grafting (CABG) aimed to provide optimized analgesia for both the sternum and the chest tubes area by combining parasternal block (PSB) and serratus anterior plane block (SAPB). METHODS: Ethics committee approval (E.Kurul-E2-24-6176, 07/02/2024) was received for the study. Then, the trial was registered on www. CLINICALTRIALS: gov ( https://clinicaltrials.gov/ ) under the identifier NCT05427955 on 17/03/2024. Twenty patients between the ages of 18-80, with ASA physical status classification II-III, undergoing coronary artery bypass grafting CABG with sternotomy, were included. While the patients were under general anesthesia, PSB was performed through the second and fourth intercostal spaces, and SAPB was performed over the sixth rib. The primary outcome was VAS (Visual Analog Scale) during the first 12 h after extubation. The secondary outcomes were intraoperative remifentanil consumption and block-related side effects. RESULTS: The average age of the patients was 64 years. Five patients were female, and 15 were male. For the sternum area, only one patient had resting VAS scores of 4, while the VAS scores for resting for the other patients were below 4. For chest tubes area, only two patients had resting VAS scores of 4 or above, while the resting VAS scores for the other patients were below 4. The patients' intraoperative remifentanil consumption averaged 2.05 mg. No side effects related to analgesic protocol were observed in any of the patients. CONCLUSIONS: In this preliminary study where PSB and SAPB were combined in patients undergoing CABG, effective analgesia was achieved for the sternum and chest tubes area.

Comparison of Multiple Injection Costotransverse Block and Erector Spinae Plane Block for Post-Sternotomy Pain Relief in Pediatric Patients Undergoing Cardiac Surgery: A Prospective Randomized Comparative Study.

OBJECTIVE: The aim of this study was to evaluate the efficacy of ultrasound-guided multiple injection costotransverse block (MICB) and compare it with erector spinae plane block (ESPB) for poststernotomy pain relief in pediatric cardiac surgical patients. DESIGN: A prospective, randomized, double-blind, comparative study. SETTING: At a single institution tertiary referral cardiac center. PARTICIPANTS: A total of 90 children with acyanotic congenital heart disease requiring surgery via sternotomy. INTERVENTIONS: Children were allocated randomly to 1 of the 3 following groups: ESPB (group 1), MICB (group 2), or Control (group 3). Participants in groups 1 and 2 received 4 mg/kg of 0.2% ropivacaine for bilateral ultrasound-guided block after induction of anesthesia. Postoperatively, intravenous paracetamol was used for multimodal analgesia, and fentanyl/tramadol was used for rescue analgesia. MEASUREMENTS AND MAIN RESULTS: The modified objective pain score (MOPS) was evaluated at 0, 1, 2, 4, 6, 8, 10, and 12 hours postextubation. After all exclusions, 84 patients were analyzed. The MOPS score was found to be significantly lower in ESPB and MICB groups compared to the control group until 10 hours postextubation (p < 0.05), with no statistically significant difference at the 12th hour (p = 0.2198). The total intraoperative fentanyl consumption (p = 0.0005), need for fentanyl supplementation on incision (p < 0.0001), and need for rescue opioid requirement in the postoperative period (p = 0.034) were significantly lower in both the ESPB and MICB groups than the control group. There were no statistically significant differences in both primary and secondary outcomes between the ESPB and MICB groups. CONCLUSION: Ultrasound-guided MICB was effective and comparable to ESPB for post-sternotomy pain management in pediatric cardiac surgical patients.

Efficacy of Incisional Ropivacaine Infiltration by Presternal Multi-Orifice Catheter for Post-sternotomy Pain Relief in Pediatric Patients Undergoing Cardiac Surgery: A Prospective, Randomized, Controlled Study.

OBJECTIVE: To evaluate the efficacy of incisional ropivacaine infiltration by presternal multi-orifice catheter to manage poststernotomy pain in pediatric cardiac surgery. DESIGN: A prospective, randomized, and double-blind comparative study. SETTING: At a single-institution tertiary referral cardiac center. PARTICIPANTS: The study comprised 200 children undergoing cardiac surgeries through a midline sternotomy. INTERVENTIONS: Children were allocated randomly to 1 of 3 groups. Group A (n = 65) and group B (n = 64) received 0.375% ropivacaine infusion and intermittent bolus, respectively, by presternal multi-orifice catheter, whereas Group C (n = 64) did not receive any local anesthetic (LA) drug. Postoperatively, intravenous paracetamol was used for multimodal analgesia, and fentanyl was given as rescue analgesia, respectively. MEASUREMENTS AND MAIN RESULTS: Pain was assessed by a Modified Objective Pain Score (MOPS) for 48 hours postextubation. Group B had significantly lower early MOPS at the first hour, but in the later period, the mean MOPS was lower in group A. The requirement of the first rescue analgesia was 3 ± 1.51, 6.1 ± 2.26, and 2.6 ± 0.87 hours for groups A (n = 60), B (n = 60), and C (n = 60), respectively. The 48-hour fentanyl consumption was significantly lower (p < 0.001) in group A (0.5 ± 0.68 µg/kg) and group B (0.7 ± 0.86 µg/kg) than the control group (3.4 ± 0.68 µg/kg). The length of intensive care unit stay was lower (p < 0.001) in groups A and B than in group C; however, the length of hospital stay was comparable (p = 0.07). CONCLUSION: LA bolus and infusion through presternal multi-orifice catheter provided effective analgesia postoperatively. However, the bolus was more efficacious in the early phase but equivalent in later periods. Therefore, bolus and LA infusion can be used for steady poststernotomy pain relief in children undergoing cardiac surgeries.

Pain and Functionality Following Sternotomy: A Prospective 12-Month Observational Study.

OBJECTIVE: To document pain levels, functionality, and analgesic use in the 12 months following a sternotomy to identify factors associated with the development of persistent post-sternotomy pain. DESIGN: Prospective observational study. SETTINGS: Royal Hobart Hospital, Australia. SUBJECTS: Patients undergoing a sternotomy between January and November 2013. METHODS: One hundred and ten patients were recruited and followed for 12 months, with telephone calls at 10 days, 6 weeks, 3 months, and 12 months. An initial survey was completed at the point of recruitment including patient history, depression and anxiety scales, self-rated health, and pain catastrophizing scale. RESULTS: The mean age of participants was 69.6 years, with the majority of participants being male (84.5%). The proportion of patients reporting pain in the early post-discharge period was high, with 30% of patients experiencing on average moderate-severe pain in the 10 days following discharge and 11% experiencing on average moderate-severe pain at 6 weeks. At 12 months, 15.5% of participants reported on average mild pain and 0.9% an average of moderate-severe pain in the preceding week at their sternotomy site. Pain of neuropathic origin was reported by 41.2% of those with on average daily pain at 12 months. CONCLUSION: This study highlights the need for further research to investigate whether more intensive pain management in the post-discharge period following sternotomy as well as the early identification of patients with neuropathic pain symptoms can reduce the incidence of persistent post-operative pain at 12 months.

Pectoral-intercostal fascial plane block in chronic post-sternotomy pain.

Persistent poststernotomy pain (PSP) is a well-known entity following cardiac surgery done with midline strenotomy. The severity of pain is usually mild to moderate in the majority of the patients. However, a small percentage of patients develop severe and persistent pain and need aggressive treatment. Our patient, a 63-year-old lady developed chronic severe parasternal pain following coronary artery bypass graft surgery. As multiple medications did not relieve her pain effectively, we did an ultrasound-guided pectoral-intercostal fascial plane block to which she responded with excellent and long-lasting pain relief. This is the first such case report of the use of this novel block technique for treating PSP.

Pain perception assessment using the short-form McGill pain questionnaire after cardiac surgery.

BACKGROUND: Pain management remains an integral part of patient care after cardiac surgery, and it required proper pain assessment. The aim of the study was to assess pain perception using validated Arabic version of the short-form McGill Pain Questionnaire (SF-MPQ) and to identify analgesics prescribing patterns post cardiac surgery. METHODS: This is a prospective study conducted in an adult cardiac critical care unit of a tertiary cardiac center from September 2018 to March 2019. The study enrolled 74 patients who underwent cardiac surgical procedures through a median sternotomy. RESULTS: The mean age of our patients was 57 ± 11 years and 47 (63.5%) were males. Patients described post-cardiac surgery pain as heavy (n = 37; 50%) and tiring-exhausting (n = 49; 66%), mainly at the site of incision (n = 20; 27%). Pain intensity at day 1 according to pain rating index (PRI) and numerical rating scale (NRS) was 7 (25th, 75th percentiles: 2.8-15) and 6 (3-8), respectively. There was a significant change in pain intensity score between 2 days of assessment (PRI: 7 [2.8-15] vs 5 [2-11] P = 0.010; NRS: 6 (3-8) vs 5 (2-8), P = 0.021]). The most common analgesics prescribed were paracetamol (39%) and a combination of tramadol and paracetamol (33.8%). CONCLUSION: Pain decreased the second day after cardiac surgery compared to day 1. Paracetamol was the most prescribed analgesic; however, there was an underutilization which might be affected by insufficient pain reporting. Future improvement could focus on multimodal pain management and proper communication of pain experience.

Post-sternotomy pain syndrome following cardiac surgery: case report.

Over 2 million people undergo sternotomy worldwide for heart surgery each year, and many develop post-sternotomy pain syndrome (PSPS) which persists in the anterior thorax. In some patients, PSPS lasts for many years or suddenly reappears a long time after the sternotomy. The exact etiology of PSPS is unknown. This article presents a case report of a patient with a diagnosis of PSPS (after cardiac surgery 4 years prior) for whom an osteopathic approach was used, which successfully eliminated the pain. In a previous study, we demonstrated that this osteopathic procedure could reduce sternal pain associated with a recent surgical wound. Further efforts are needed to understand the reasons for PSPS. In light of new scientific data, these osteopathic techniques could contribute to a multidisciplinary approach to solve the problem.
