Unusual Presentation of Pneumocephalus With Late Onset During Labour Epidural Analgesia.

A 36-year-old woman with no significant medical history was in active labour and requested labour analgesia. While the epidural technique was performed at the L4-L5 interspace, using the loss of resistance to air technique (LORA), inadvertent dural puncture occurred. Since the patient reported no headache or discomfort, the same procedure was repeated at the L3-L4 interspace successfully. Loss of resistance was reported at 3 cm and the epidural catheter was advanced uneventfully at 8 cm. Aspiration was negative for blood or cerebrospinal fluid (CSF) and a test dose of 2 ml lidocaine 2% was administered epidurally. Within five minutes the patient exhibited a mild hypotensive episode successfully treated with 2.5 mg ephedrine IV, a sensory blockade up to T6 level, and a motor blockade up to T10 level. Both the woman's and the baby's vital signs remained stable, no further drugs were administered epidurally and labour progressed painlessly and uncomplicated for 90 minutes with subsequent vaginal delivery of a healthy newborn. During the episiotomy incision repair, the patient complained of light dizziness and nausea. Her vital signs and the arterial blood gases (ABGs) ordered were within normal range, but the neurological examination revealed an isolated Babinski on the right foot. The head CT scan requested indicated a considerable quantity of air within the subarachnoid region. The patient was treated conservatively; symptoms showed steady improvement with total resolution on the sixth day, and the woman was discharged. This case reemphasizes the possibility of pneumocephalus, which may, in reality, occur more frequently than is commonly recognized without a CT confirmation.

Music's use for anesthesia and analgesia.

This review article provides an overview of published data regarding the involvement of music in anesthesia practice. Music is an important topic for research in different fields of anesthesiology. The use of music preoperatively is aimed at reducing anxiety, stress, and fear. However, the effect of music on perception of pain intraoperatively is controversial, according to studies of both adults and children undergoing various surgical procedures under general and/or regional anesthesia. In postoperative pain management, postanesthesia care, and neonatal intensive care, music can be a complementary method for reducing pain, anxiety, and stress. Music is a mild anxiolytic, but it is relatively ineffective when a pain stimulus is severe. However, music is inexpensive, easily administered, and free of adverse effects, and as such, can serve as complementary method for treating perioperative stress and for acute and chronic pain management, even though music's effectiveness depends on each individual patient's disposition and severity of pain stimulus.
