Unexplained fitting in patients with post-dural puncture headache. Risk of iatrogenic pneumocephalus with air rationalizes use of loss of resistance to saline

Tonic-clonic seizure after unrecognized unintentional dural puncture

Patients who suffer an unintentional dural puncture have a high risk of developing a post-dural puncture headache. Other neurologic complications have been reported, but seizure is rarely seen. We present a case of a 21-year-old primigravida who experienced an unrecognized unintentional dural puncture that ultimately resulted in a tonic-clonic seizure from intracranial hypotension one week following the dural breach. Her trachea was intubated and she was transferred to the intensive care unit. Two epidural blood patches, performed by neuroradiologists, were needed before the patient experienced complete resolution of her headache. During the re-admission, she also experienced a pulmonary embolus which further lengthened her hospital stay.

Case Report: Pneumocephalus after labor epidural anesthesia

Lumbar epidural anesthesia is commonly used for labor analgesia. The 'loss-of- resistance' to air technique (LORA) is generally employed for recognition of the epidural space. One of the rare complications of this technique is pneumocephalus (PC). Here we describe the case of a parturient who developed a frontal headache when locating the epidural space using LORA. On the second day after epidural injection, the patient exhibited occipital headaches with gradual worsening. Computed tomography scans of the brain indicated PC. Following symptomatic treatment, our patient was discharged on the 13th day. We concluded that the amount of air used to identify the epidural space in LORA should be minimized, LORA should not be used after dural puncture and the use of saline avoids PC complications.

Seizures in the early post-partum period: A diagnostic dilemma

We discuss the differential diagnosis and management of early post-partum seizures and headache following a presumed dural puncture in a 20-year-old female. She initially presented with generalised tonic-clonic seizures preceded by nausea and headache on the fourth post-partum day along with a decreased Glasgow Coma Scale (8/15). Although clinical and laboratory examination including lumbar puncture, computerized tomography and magnetic resonance imaging were normal, a persistent headache was the only symptom. This headache improved dramatically after an epidural blood patch on the eighth post-partum day. The following discussion emphasises that various causes of post-partum seizures and headache should be considered before attributing it to dural puncture alone.

Pneumocephalus in a patient with no cerebrospinal fluid leakage after lumbar epidural block - a case report -

Several complications are possible after a lumbar epidural block. However pneumocephalus are rare. In this case, we report a case of pneumocephalus. A 68-year-old male patient received lumbar epidural block with the loss of resistance technique using air, and after 35 minutes, apnea, unconsciousness, hypotension, and bradycardia occurred. Immediately, brain CT was done, and we found pneumocephalus. The patient complained of severe occipital headache and itchiness due to pneumocehalus. After conservative treatment, the patient recovered without neurologic complications, and on the seventh day of his hospitalization, he was discharged from the hospital.

Anesthesia complications in the birthplace: is the neuraxial block always to blame?

This article highlights the common and some of the very serious complications that may occur following neuraxial analgesia for labor and delivery, including headache, backache, infection, hypotension, and hematoma. Total spinal and failed block also are discussed, as are complications unique to epidural anesthesia, such as the intravascular injection of large volumes of local anesthetic (causing seizure or cardiac arrest) and accidental dural puncture.

A case of late postpartum seizures after epidural analgesia

We present the case of a 29-year-old female who in her third pregnancy developed seizures seven days postpartum. The only symptoms preceding the seizures were headache and visual disturbance. There was no evidence of preeclampsia antepartum or postpartum. All clinical investigations were normal including computerised tomography, magnetic resonance imaging and lumbar puncture. All symptoms resolved within 24 h of the first seizure. In this case report we highlight the difficulties in establishing the cause of postpartum seizures.
