Fascial plane blocks for cardiothoracic surgery: a narrative review.

In recent years, there has been a growing awareness of the limitations and risks associated with the overreliance on opioids in various surgical procedures, including cardiothoracic surgery.This shift on pain management toward reducing reliance on opioids, together with need to improve patient outcomes, alleviate suffering, gain early mobilization after surgery, reduce hospital stay, and improve patient satisfaction and functional recovery, has led to the development and widespread implementation of enhanced recovery after surgery (ERAS) protocols.In this context, fascial plane blocks are emerging as part of a multimodal analgesic in cardiac surgery and as alternatives to conventional neuraxial blocks for thoracic surgery, and there is a growing body of evidence suggesting their effectiveness and safety in providing pain relief for these procedures. In this review, we discuss the most common fascial plane block techniques used in the field of cardiothoracic surgery, offering a comprehensive overview of regional anesthesia techniques and presenting the latest evidence on the use of chest wall plane blocks specifically in this surgical setting.

Continuous Erector Spinae and Serratus-Intercostal Block With Ketamine-Dexmedetomidine Sedation for Quadrantectomy and Axillary Dissection in a Multimorbid Patient.

Multimorbidity is a clinical presentation that poses an increased risk of perioperative and postoperative complications. Tailored anaesthetic management could potentially minimise the risk of negative outcomes. Peripheral nerve and fasciae blocks are valid strategies for perioperative and postoperative pain management, which avoid complications related to general anaesthesia and reduce the risk of intensive care unit admission as well as the hospital length of stay. We describe the case of a 56-old patient with multimorbidity, including obesity with a BMI of 45.7, unstable angina, predicted difficult airway management and obstructive sleep apnoea syndrome (OSAS) scheduled for left mastectomy with sentinel lymph node biopsy, managed with a left continuous thoracic erector spinae plane (ESP) block plus serratus-intercostal plane block (BRanches of Intercostal nerves at the Level of Mid-Axillary line (BRILMA)), and sedation with combined ketamine-dexmedetomidine. Fascial blocks combined with opioid-free anaesthesia (OFA) proved to be effective for the multimorbid patient, ensuring successful perioperative management and a proper recovery after surgery.

Fascial Plane Blocks Combination for Breast Surgery in Obese Patients With Difficult Airway Management: Insidious or a Valid Alternative.

Obesity poses several challenges for anesthetists. The several comorbidities associated with obesity can result in very complex management, which requires a multimodal and reasoned approach. The possible difficult airways are, certainly, the obstacle that most can put the anesthetist to the test. From this point of view, regional anesthesia (RA) can be a valid alternative to general anesthesia (GA) in selected patients. The possibility of performing an anesthetic block allows the fulfilment of the surgical act. We present the case of a 56-year-old woman, with a BMI of 43. In her medical history, she has obstructive sleep apnea syndrome (OSAS) on home-oxygen therapy without continuous positive airway pressure (CPAP) therapy. The patient reported probable airway difficulties in previous breast surgery, and the preoperative evaluation highlighted and confirmed the high risk. For this reason, in agreement with the surgeons and the patient, we decided to perform RA. Forty minutes before the start of the surgery, a deep anesthetic ultrasound-guided serratus anterior plane (US-SAP; branches of the intercostal nerves in the middle axillary line [BRILMA]) was performed, followed by a right ultrasound-guided erector spinae plane (US-ESP) block. Mild sedation with propofol 1 mg/kg/h was administered and SpO2 always remained above 97% with nasal oxygen at 3 l/min. The surgery was completed in 35 minutes, the patient complained of no pain, and received opioid rescue therapy during the post-operative period. This case presents clinical evidence that RA can help in avoiding some dreadful complications that can occur during GA in obese patients. In any case, the anesthetic management choice must be carefully reasoned, considering the patient's clinical conditions, surgical needs, and, not least, the skills of the anesthetist.

Continuous Wound Infiltration of Local Anesthetics in Postoperative Pain Management: Safety, Efficacy and Current Perspectives.

Local infiltration and continuous infusion of surgical wound with anesthetics are parts of multimodal analgesia for postoperative pain control. The techniques, given the simplicity of execution that does not increase the timing of the intervention and does not require additional technical skills, are applied in several kinds of surgeries. The continuous wound infiltration can be used for days and a variety of continuous delivery methods can be chosen, including patient-controlled analgesia, continuous infusion or intermittent bolus. The purpose of this narrative review is to analyze the literature, in particular by researching the safety, efficacy and current perspectives of continuous wound infiltration for postoperative pain management in different surgical settings. We have identified 203 articles and 95 of these have been taken into consideration: 17 for the lower limb surgery; 7 for the upper limb surgery, 51 for the laparotomy/laparoscopic surgery of the abdominopelvic area, 13 studies regarding breast surgery and 7 for cardiothoracic surgery. The analysis of these studies reveals that the technique has a variable effectiveness based on the type of structure involved: it is better in structures rich in subcutaneous and connective tissue, while the effectiveness is limited in anatomic districts with a greater variability of innervation. However, regardless the heterogeneity of results, a general reduction in pain intensity and in opioid consumption has been observed with continuous wound infiltration: it is an excellent analgesic technique that can be included in the multimodal treatment of postoperative pain or represents a valid alternative when other options are contraindicated.

Serratus anterior plane block in subcutaneous implantable cardioverter defibrillator implantation: A case-control analysis.

BACKGROUND: A two-incision technique, in association with inter-muscular positioning of the subcutaneous defibrillator (S-ICD), is now the most frequently adopted implantation approach in Europe. Ultrasound-guided serratus anterior plane block (SAPB) has been proposed to provide anesthesia/analgesia during S-ICD implantation. OBJECTIVE: We performed a case-control analysis in which a standardized SAPB approach was compared with the typical local anesthesia and sedation approach. METHODS: Ninety-one consecutive patients underwent implantation of an S-ICD with the SAPB approach for anesthesia/analgesia at 10 centers. The control group consisted of 55 consecutive patients who underwent S-ICD implantation with a standard local approach. RESULTS: The mean procedure duration was 59 ± 15 minutes in the SAPB group and 76 ± 23 minutes in the control group (P < .001). No operative complications were reported in either group. During the procedure, 79 (87%) patients in the SAPB group and 25 (46%) patients in the control group (P < .001) remained awake. Lower values of pain intensity at the device pocket (P = .005) and the lateral tunneling site (P = .046) were reported in the SAPB group. The difference in static (P = .002) and dynamic (P = .007) pain intensity between the groups persisted at 1 hour, while no differences were observed 6 hours after the end of the procedure. CONCLUSIONS: SAPB is feasible and effective in providing anesthesia/analgesia during S-ICD implantation. The procedures were successfully accomplished and no complications occurred in either group. However, SAPB was associated with lower pain levels, enabling the need for sedation to be reduced and more patients to remain awake. Moreover, it resulted in shorter procedure durations.

Continuous wound infusion and local infiltration analgesia for postoperative pain and rehabilitation after total hip arthroplasty.

BACKGROUND: Total hip arthroplasty is one of the most common procedures in orthopedic surgery. We hypothesized that local infiltration of analgesia and continuous wound infusion of anesthetics in the first 72 hours after surgery could provide more effective postoperative analgesia with better rehabilitation. METHODS: A double-blind, randomized, controlled study was conducted with 96 patients who underwent total hip arthroplasty. The patients were randomized to receive either a local infiltration analgesia and continuous wound infusion of anesthetics or a local infiltration analgesia and continuous wound infusion of saline solution. The patients in both groups received subarachnoid anesthesia and a local infiltration analgesia. A multihole catheter was placed next to the implant and connected to an electronic pump containing a 300-mL solution of 0.2% levobupivacaine (experimental group) or saline (control group). RESULTS: A total of 96 consecutive patients were enrolled and randomized. Of these, 48 patients received local infiltration analgesia and continuous wound infusion of local anesthetics, and the remainder received local infiltration analgesia and continuous wound infusion of saline solution. The analysis showed a significant main effect of treatment on the postoperative incident of pain (Ftreat(1,93)=22.62, P=0.000) and on resting pain during the post-surgery follow-up (Ftreat(1,93)=15.62, P=0.0002). The pain scores during the rehabilitation period were significantly less in the experimental group. Analgesic consumption was less in the experimental group. CONCLUSIONS: The addition of continuous wound infusion of anesthetics to local infiltration analgesia provided an extended analgesic effect associated with good rehabilitation performance.
