Manual hyperinflation is associated with a low rate of adverse events when performed by experienced and trained nurses in stable critically ill patients--a prospective observational study.
Manual hyperinflation (MH) can be performed as part of airway management in intubated and mechanically ventilated patients to mobilize airway secretions. Although previous studies demonstrated MH to be associated with hemodynamic and respiratory instability, we hypothesized MH to cause fewer adverse events (AEs) when performed by experienced and trained nurses in stable critically ill patients. ⋯ The rate of hemodynamic and respiratory AEs with MH is low when performed by experienced and trained nurses in stable, critically ill patients. MH, however, may induce or increase anxiety/agitation. We consider MH a safe maneuver in stable ICU patients in our setting.

Case ReportsAcute subdural intracranial hematoma after combined spinal-epidural analgesia in labor.
Intracranial subdural hematoma is a rare, but well-described complication of epidural and spinal anesthesia, as documented by more than a decade of publications. Non-postural headache and vomiting are warning signs. A headache lasting more than 5 days should arouse suspicion of intracranial hemorrhage, whether or not it is associated with the appearance of neurological signs or the deterioration of neurological status. ⋯ We report the case of a patient who suffered from severe neurological deterioration and manifested signs of brain herniation due to the development of an acute intracranial subdural hematoma after CSE analgesia for labor. An emergency craniotomy was performed to remove the subdural hematoma and the patient recovered well. Close observation of patients undergoing CSE analgesia or anesthesia complaining of prolonged non-postural headaches, with or without neurological symptoms, is recommended.

Case ReportsParesis of cranial nerve VI (N. abducens) after thoracic dural perforation.
Epidural anesthesia is associated with the risk of unintended dural perforation and concomitant leakage of cerebrospinal fluid (CSF) from the subarachnoidal space. This may remain asymptomatic or trigger post-dural puncture headache (PDPH). ⋯ Herein, diagnosis of N. abducens paresis was probably delayed because the optical symptoms, such as blurred and double vision, were attributed to optical hallucinations caused by a concomitant (S)-ketamine infusion. In all patients with optical symptoms such as blurred or double vision a paresis of the abducens nerve should be considered.

Case ReportsLocal anesthetic toxicity in interscalene block: clinical series.
We experienced two cases of local anesthetic toxicity by interscalene block. A 62-year-old man received interscalene block with lidocaine 1% 30 mL and bupivacaine 0.25% 20 mL under light sedation followed by general anesthesia. He was not awake at one hour after surgery with his pupils dilated. ⋯ Seizure stopped in two min after anesthesia induction. She had no complication after surgery. These two cases showed neurological toxicity by interscalene block with lidocaine and bupivacaine or with ropivacaine without hemodynamic complication.
