RESUMO
Significant advances in surgical techniques and relevant medium- and long-term outcomes over the past two decades have led to a substantial expansion in the indications for major liver resections. To support these outstanding results and to reduce perioperative complications, anesthesiologists must address and master key perioperative issues (preoperative assessment, proactive intraoperative anesthesia strategies, and implementation of the Enhanced Recovery After Surgery approach). Intensive care unit monitoring immediately following liver surgery remains a subject of active and often unresolved debate. Among postoperative complications, posthepatectomy liver failure (PHLF) occurs in different grades of severity (A-C) and frequency (9%-30%), and it is the main cause of 90-d postoperative mortality. PHLF, recently redefined with pragmatic clinical criteria and perioperative scores, can be predicted, prevented, or anticipated. This review highlights: (1) The systemic consequences of surgical manipulations anesthesiologists must respond to or prevent, to positively impact PHLF (a proactive approach); and (2) the maximal intensive treatment of PHLF, including artificial options, mainly based, so far, on Acute Liver Failure treatment(s), to buy time waiting for the recovery of the native liver or, when appropriate and in very selected cases, toward liver transplant. Such a clinical context requires a strong commitment to surgeons, anesthesiologists, and intensivists to work together, for a fruitful collaboration in a mandatory clinical continuum.
RESUMO
Background and Study Aim: Advance biliopancreatic endoscopies are nowadays performed in non-operating room anesthesia (NORA) under general anesthesia (GA). We evaluate the outcomes of non-intubated patients in prone position who received GA for endoscopic ultrasound (EUS) and endoscopic retrograde cholangiopancreatography (ERCP) in a tertiary referral center for digestive endoscopy. Patients and Methods: Anesthesiological records, anamnestic, and intraoperative data of patients who underwent advanced therapeutic biliopancreatic endoscopies at our tertiary referral center from January 2019 until January 2020 were collected in the present observational study. Results: One hundred fifty-three patients (93 M; median age: 68-year-old; mean ASA status: 2) were considered eligible for a procedure in the prone position with GA in spontaneous breathing. Prone position was always the initial setting. Propofol administration through a target-controlled infusion (TCI) pump was the choice to achieve GA. In our experience, desaturation appears to be the most frequent adverse event, accounting for 35% of cases (55/153). Treatment foresaw additional oxygen through a nasopharyngeal catheter, which proved to be a sufficient measure in almost all patients (52/55). Other adverse events (i.e., inadequate sedative plan, pain, and bradycardia) accounted for 2.6% of cases (4/153). Conclusions: Non-intubated GA in the prone position may be regarded as a safe procedure, as long as the anesthesiological criteria of exclusion are respected and the anesthesiological team has become acquainted with the peculiar NORA setting and familiar with the management of possible adverse events.
RESUMO
No major complications have been associated with the ultrasound-guided continuous adductor canal block (cACB). We present a case of iatrogenic pseudoaneurysm in a branch of the superficial femoral artery in a 44-year-old patient after a cACB for knee surgery. Both anesthesia and surgery were completed uneventfully. The postoperative day 3 examination showed a complete quadricep impairment and a large hematoma in a medial-anterior part of the thigh, and laboratory tests reported hemoglobin = 7.2 g dL. The computed tomography scan revealed the pseudoaneurysm (16 × 16 × 18 mm) that was successfully embolized after selective catheterization. The patient was discharged regularly on postoperative day 12.
