Regional analgesia for lung transplantation: A narrative review.

Lung transplantation (LTx) is the definitive treatment for end-stage pulmonary disease. About 4500 LTxs are performed annually worldwide. It is considered challenging and complex surgery regarding anaesthesia and pain management. While providing adequate analgesia is crucial for patient comfort, early mobilisation and prevention of postoperative pulmonary complications, standardising an analgesic protocol is challenging due to the diversity of aetiologies, surgical approaches and the potential use of extracorporeal life support (ECLS). Although thoracic epidural analgesia is commonly considered the gold standard, concerns regarding procedural safety and its potential for devastating consequences have led physicians to seek safer analgesic modalities such as thoracic nerve blocks. The advantages of thoracic nerve blocks for general thoracic surgery are well established. However, their utility in LTx remains unclear. Considering paucity of relevant literature, this review aims to raise awareness about the literature gap in the field and highlight the need for further high-quality studies determining the effectiveness of available techniques.

Long-term psychological and physical outcomes of women after postdural puncture headache: A retrospective, cohort study.

BACKGROUND: Postdural puncture headache after accidental dural puncture during labour may lead to chronic sequalae. OBJECTIVES: We aimed to measure the incidence of postpartum depression, posttraumatic stress disorder, chronic headache, backache and breastfeeding rates after a postdural puncture headache. DESIGN: A retrospective, case-matched cohort study. SETTING: A review of documented cases of dural puncture and matched case controls occurring at Rabin Medical Center and Shamir Medical Center from 01 January 2012 to 30 September 2018. PATIENTS: The study cohort consisted of women with a documented postdural puncture headache and the controls were women with uneventful labour epidurals in the same 24-h period. Women were interviewed by telephone. PRIMARY OUTCOMES MEASURE: The primary outcome measure was the incidence of postpartum depression after a postdural puncture headache. RESULTS: Women with postdural puncture headache (n = 132) and controls (n = 276) had similar demographic data. The incidence of postpartum depression was 67/128 (52.3%) versus 31/276 (11.2%) for controls, P < 0.0001, 95% confidence intervals of the difference 31.5 to 50.2. Posttraumatic stress disorder was more frequent among women with postdural puncture headache, 17/132 (12.8%) versus controls 1/276 (0.4%), P < 0.0001, 95% confidence intervals of the difference 7.6 to 19.5. Women with postdural puncture headache breastfed less, 74/126 (54.5%) versus controls 212/276 (76.8%), P < 0.0001, 95% confidence intervals of the difference 33.1 to 55.2. Current headache and backache were significantly more frequent among women with postdural puncture headache [current headache 42/129 (32.6%) versus controls 42/276 (15.2%) P < 0.00001, 95% confidence intervals 0.085 to 0.266; current backache 58/129 (43.9%) versus controls 58/275 (21%) P < 0.0001, 95% confidence intervals 14.1 to 33.5]. CONCLUSION: We report an increased incidence of postpartum depression, posttraumatic stress disorder, chronic headache and backache and decreased breastfeeding following a postdural puncture headache. Our findings emphasise the need for postpartum follow-up for women with postdural puncture headache. TRIAL REGISTRY NUMBER: Clinical trial registry number: NCT03550586.

[MALIGNANT HYPERTHERMIA].

INTRODUCTION: In this article we describe the treatment of a patient who developed suspicious symptoms of malignant hyperthermia syndrome during anesthesia for elective cerebral catheterization. We also described an up-to-date review of malignant hyperthermia, diagnosis and treatment. Details regarding the case: this is a case of a 57 year old male patient who was admitted for an elective catheterization under general anesthesia. Four hours following anesthesia induction, the patient presented with the following symptoms: a gradual increase in end tidal carbon dioxide measurements, an elevated core temperature, tachycardia, decreased oxygen saturation and excessive sweating. Arterial blood gases indicated respiratory acidosis. With a clinical diagnosis of malignant hyperthermia, the catheterization procedure was stopped. The patient was disconnected from the anesthesia machine and was ventilated with a clean ventilator with 100% oxygen. Additionally, active patient cooling was initiated along with supportive pharmacologic treatment. The patient was then moved, anesthetized and ventilated into the post anaesthesia care unit. Following a clinical and laboratory improvement the patient was extubated.

No longer rare diseases and obstetric anesthesia.

PURPOSE OF REVIEW: With new medical technologies and changing life styles, maternal demographics has changes and consequently older and sicker women are becoming pregnant.In this review, we present these different high-risk parturient populations, which were once considered rare for the practicing obstetric anesthesiologist. RECENT FINDINGS: With lifestyle and medical advances, older and sicker women are getting pregnant. Older women are more prone to pregnancy complications. Cancer survivors are becoming pregnant and more pregnant women are being diagnosed with cancer. Previous neurological and cardiac conditions considered not compatible with pregnancy are now seen more frequently. As the rate of obesity increases so does the rate of obstructive sleep apnea, which is known to be associated with many adverse maternal and neonatal sequalae. Finally, increased use of both opioids and marijuana has led to increased number of pregnant women using these illicit substances. SUMMARY: Future research and implementation of international guidelines for management of these high-risk parturient population is necessary in order to reduce maternal and neonatal morbidity.

Additive value of superficial parasternal intercostal plane block and serratus anterior plane block in lung transplantation surgery: a retrospective exploratory study.

BACKGROUND: Adequate pain control following lung transplantation (LTx) surgery is paramount. Thoracic epidural analgesia (TEA) is the gold standard; however, the potential use of extracorporeal membrane oxygenation (ECMO) and consequent anticoagulation therapy raises safety concerns, prompting clinicians to seek safer alternatives. The utility of thoracic wall blocks in general thoracic surgery is well established; however, their role in the context of LTx has been poorly investigated. METHODS: In this retrospective exploratory study, we assessed the effect of adding a superficial parasternal intercostal plane (sPIP) block and serratus anterior plane (SAP) block to standard anesthetic and analgesic care on tracheal extubation rates, pain scores and opioid consumption until 72 hours postoperatively in LTx. RESULTS: Sixty patients were included in the analysis; 35 received the standard anesthetic and analgesic care (control group), and 25 received sPIP and SAP blocks in addition to the standard anesthetic and analgesic care (intervention group). We observed higher tracheal extubation rates in the intervention group at 8 hours postoperatively (16.0% vs 0.0%, p=0.03). This was also shown after adjusting for known prognostic factors (OR 1.18; 95% CI 1.04 to 1.33, p=0.02). Furthermore, we noted a lower opioid consumption measured by morphine milligram equivalents at 24 hours in the intervention group (median 405 (IQR 300-490) vs 266 (IQR 168-366), p=0.02). This was also found after adjusting for known prognostic factors (ß -118; 95% CI -221 to 14, p=0.03). CONCLUSION: sPIP and SAP blocks are safe regional analgesic techniques in LTx involving ECMO and clamshell incision. They are associated with faster tracheal extubation and lower opioid consumption. These techniques should be considered when TEA is not appropriate. Further high-quality studies are warranted to confirm these findings.
