A case report of intracranial hemorrhage after spinal anesthesia

Abstract Background Chronic subdural hematoma (CSDH) after spinal anesthesia is a rare complication. We experienced a patient who developed CSDH after postdural puncture headache (PDPH) following combined spinal and epidural anesthesia (CSE). Case presentation A 38-week-gestation parturient with a history of previous cesarean delivery underwent elective cesarean section under CSE. She had been receiving aspirin therapy for Kawasaki disease for many years. She developed a symptom of PDPH 1 day after the surgery. Fluid administration and analgesics were started. Although the headache was relatively severe and persistent, it suddenly disappeared on the third postoperative day. Aspirin administration was restarted on the third postoperative day, and the patient was discharged 1 week after the surgery. 2 weeks after being discharged, she was readmitted to our hospital for severe headache and was diagnosed as having CSDH. An epidural blood patch was performed, resulting in resolution of the hematoma. Conclusions We experienced a case of CSDH after PDPH in a patient who was receiving aspirin therapy. Aspirin therapy should be restarted after confirmation of the absence of headache. We should consider the possibility of unexpected disappearance of PDPH in the postoperative period may be due to the development of CSDH

Skin Testing to Identify Safe Drugs for Patients with Rocuronium-Induced Anaphylaxis

Among patients who develop anaphylaxis during anesthesia, anaphylaxis caused by a neuromuscular blocking agent has the highest incidence. In patients who developed IgE-mediated anaphylaxis, and cross-reactivity among NMBAs is a concern in subsequent anesthetic procedures. We present a patient who developed rocuronium-induced anaphylaxis in whom the skin prick test (SPT) and intradermal test (IDT) could identify a safe drug to use in the subsequent anesthetic procedure. A 32-year-old female developed anaphylactic shock at the induction of general anesthesia. She recovered by administration of hydrocortisone and epinephrine. Skin tests including the SPT followed by the IDT revealed rocuronium as the drug that caused anaphylaxis and vecuronium as a safe drug to use for the subsequent general anesthesia. She safely underwent surgery with general anesthesia using vecuronium one month after the skin testing. There are not many reports on the effectiveness of the SPT followed by IDT in identifying the causative drug as well as a safe drug to use in the subsequent anesthetic procedure following anaphylaxis during anesthesia. The usefulness of the SPT should be re-evaluated

Anaesthetic management of an abdominal aortic aneurysmorrhaphy in Klippel-Trenaunay-Weber syndrome: a case report

Abstract Background Klippel-Trenaunay-Weber syndrome (KTWS) is a rare congenital malformation. Although there have been few reports on anaesthetic management of patients with KTWS, there is a lack of data on anaesthetic management for abdominal aortic aneurysm (AAA) surgeries in these patients. Case presentation A 74-year-old man (height, 160 cm and body weight, 51.5 kg) with KTWS was scheduled for AAA replacement. Abdominal computed tomography (CT) showed prominent tortuosity below the abdominal aorta with an infrarenal abdominal aortic aneurysm, right common iliac artery aneurysm, and right external iliac artery aneurysm. Moreover, a remarkably noted arteriovenous fistula had developed between the aneurysm and peripheral artery. General anaesthesia was induced. Furthermore, a central venous catheter and an 8.5 French sheath in the left internal jugular vein were inserted. During the operation, bleeding from a collateral vessel in the cross-clamped aorta led the surgeon to decide to perform aneurysmorrhaphy. Intraoperatively, blood loss was 1500 ml, and 20 units of red blood cell concentrate were used. Conclusions Regarding AAA procedures in patients with KTWS, aortic cross-clamping may not sufficiently intercept blood flow due to collateral vessels. In these patients, the anaesthesiologist must be prepared to transfuse blood more rapidly and frequently than during normal AAA procedures

Negative Pressure Pulmonary Edema after Reversing Rocuronium-Induced Neuromuscular Blockade by Sugammadex

Negative pressure pulmonary edema (NPPE) is a rare complication that accompanies general anesthesia, especially after extubation. We experienced a case of negative pressure pulmonary edema after tracheal extubation following reversal of rocuronium-induced neuromuscular blockade by sugammadex. In this case, the contribution of residual muscular block on the upper airway muscle as well as large inspiratory forces created by the respiratory muscle which has a low response to muscle relaxants, is suspected as the cause

Remifentanil-induced alterations in neutrophil numbers after surgery

Abstract Background Neutrophils are the first line of defense against invasive microorganisms during and after surgery. There is a possibility that different opioid analgesics used during surgery have different effects on the leucocyte count. We retrospectively analyzed the numbers of leucocytes, neutrophils, and lymphocytes just after surgery in patients who received remifentanil-based anesthesia and those who received fentanyl-based anesthesia. In female patients who underwent modified mastectomy or simple mastectomy with resection of a lymph node(s) or with biopsy of a sentinel lymph node(s) between January 2010 and December 2013 (n = 83), propensity score pairwise matching was performed according to the patient’s age and procedure, and forty patients (Remifentanil group and Fentanyl group; n = 20 each) were analyzed. Findings Postoperative numbers of leucocytes and neutrophils were significantly lower in patients who received remifentanil-based anesthesia than in those who received fentanyl-based anesthesia (p = 0.03, p = 0.014; leucocytes and neutrophils, respectively). The increases in the numbers of leucocytes and neutrophils were significantly lower in the patients in the remifentanil group (p = 0.009, p = 0.0046; increase in leucocytes and neutrophils, respectively). Conclusions In conclusion, remifentanil-based anesthesia attenuates postoperative leucocyte and neutrophil counts. It is unknown whether this phenomenon indicates the possibility of immunosuppression. Further studies are required
