Likely, maintained organ and notably cerebral perfusion, secures rapid recovery following anesthesia. To secure cerebral blood flow (CBF) at least mean arterial pressure (MAP) and the arterial carbon dioxide tension (PaCO2) need to be considered. CBF is "autoregulated", i.e. stays more or less stable within a MAP of 50-150 mmHg, but the lower limit appears to depend on the central blood volume and/or cardiac output, illustrated by a decrease in CBF at a MAP of 80 mmHg with a compromised central blood volume, while CBF remains constant with a MAP < 40 mmHg, if the central blood volume is maintained...

BACKGROUND: The cerebrospinal fluid (CSF) leakage could be happened spontaneously or related to the procedures such as spinal anesthesia, epidural anesthesia, CSF tapping, intrathecal chemotherapy or other spinal procedures. The leakage of CSF leads to intracranial hypotension of which distinguishing clinical feature is orthostatic headache. The epidural blood patch is a gold-standard treatment for intracranial hypotension-related orthostatic headaches. OBJECTIVE: We conducted this study to compare the efficacy and number of epidural blood patches for spontaneous and iatrogenic orthostatic headaches...

Prompt recognition and management of hypotension resulting from aortocaval compression syndrome are essential to optimize the maternal and fetal outcomes. Management involves increasing leftward uterine displacement and sometimes full lateral positioning, although lateral position during cesarean delivery is typically considered to be impractical. We report an obstetric patient case of severe aortocaval compression syndrome resulting in hypotension and loss of consciousness that ultimately underwent cesarean delivery under general anesthesia in the lateral position...

BACKGROUND: Intraoperative hypotension may be associated with adverse outcomes in children undergoing surgery. Infants and neonates under 6 months of age have less autoregulatory cerebral reserve than older infants, yet little information exists regarding when and how often intraoperative hypotension occurs in infants. AIMS: To better understand the epidemiology of intraoperative hypotension in infants, we aimed to determine the prevalence of intraoperative hypotension in a generally uniform population of infants undergoing laparoscopic pyloromyotomy...

Congenital insensitivity to pain is a rare autosomal recessive disease characterized by varying degrees of autonomic dysfunction and sensory loss, including nociceptive hyposensitivity. It is this autonomic dysfunction that makes both general and neuraxial anesthesia challenging. Testing the block during neuraxial anesthesia may be difficult and the patient may be prone to hypotension and bradycardia. This case report describes the anesthetic management of a parturient with congenital insensitivity to pain presenting for cesarean delivery...

BACKGROUND: Dexmedetomidine, a selective alpha-2 agonist, has sedative, analgesic, and anxiolytic effects without respiratory depression. Dexmedetomidine can cause a biphasic cardiovascular response, and induce transient hypertension. Hypotension is a common complication of spinal anesthesia. Decreasing anxiety of patients before procedure is important for high quality of procedure. This study aimed to compare the incidence of hypotension and patients' anxiety and comfort levels when dexmedetomidine was intravenously administered before and after spinal anesthesia...

BACKGROUND AND OBJECTIVE: Propofol is the most commonly used intravenous (IV) anesthetic agent and is associated with hypotension upon induction of anesthesia. Intravenous propofol infusion has several properties that may be beneficial to patients undergoing middle ear surgery. Topical application of concentrated epinephrine is a valuable tool for achieving hemostasis in the middle ear and during mastoid surgery. The purpose of the present study was to determine the effects of propofol infusion with topical epinephrine on cochlear blood flow (CBF) and hearing in rats...

BACKGROUND: Perioperative seizure prophylaxis with antiepileptic drugs (AED) has been advocated in patients undergoing supratentorial craniotomy. The practice remains controversial. The reasoning presupposes that the possibility of an adverse drug reaction from the AED is lower than the probability of harm from a seizure. Even short periods of hypotension during the operation can lead to acute kidney and myocardial injury. We retrospectively evaluated cardiovascular effects and tolerability of Levetiracetam (LEV) alone, LEV and Lacosamid (LCM) as compared to Phenytoin (PHT)...

BACKGROUND AND PURPOSE: The adverse effects of general anesthesia in stroke thrombectomy have been attributed to intraprocedural hypotension, yet optimal hemodynamic targets remain elusive. Identifying hemodynamic thresholds from patients without exposure to general anesthesia may help separate the effect of hypotension from the effect of anesthesia in thrombectomy outcomes. Therefore, we investigated which hemodynamic parameters and targets best correlate with outcome in patients treated under sedation with monitored anesthesia care...
