We describe a case of intrathecal migration of a wire-reinforced epidural catheter in a parturient who received epidural labor analgesia. Epidural analgesia was initiated with a combined-spinal epidural technique and maintained by programmed intermittent epidural boluses. Epidural catheter aspiration after insertion was negative for cerebrospinal fluid. The patient's response to the first four doses of local anesthetic was consistent with epidural drug delivery. After the fifth dose, she developed a complete lower extremity motor block, hypotension, and high sensory blockade. Catheter aspiration was then positive for cerebrospinal fluid. After symptom resolution, labor pain was successfully managed with this inadvertent intrathecal catheter.

Bilateral Continuous Thoracic Paravertebral Block for the Pain Management of Multiple Rib Fractures With Flail Chest: A Case Report.

Anesthesiology, Showa University Northern Yokohama Hospital, Yokohama, JPN.
Flail chest is a life-threatening condition characterized by multiple rib fractures that result in a partially free rib cage. Thoracic paravertebral block (TPVB) allows visualization of the needle tip under ultrasound guidance and can be safely performed, unlike epidural anesthesia where the needle tip cannot be visualized. Here, we describe a case of flail chest in whom TPVB was used, as it provides the same level of analgesia as epidural anesthesia and has a perfect analgesic effect.

: Esophagectomy is a key component of esophageal cancer treatment, with minimally invasive esophagectomy (MIE) increasingly replacing open esophagectomy (OE). Effective postoperative pain management can be achieved through various analgesic modalities. This study compares the efficacy of thoracic epidural anesthesia (TEA) with non-TEA methods in managing postoperative pain following MIE.

Despite advances in procedural techniques and equipment, postdural puncture headache (PDPH) remains a serious complication of labour epidural analgesia after accidental dural puncture (ADP). Often considered a temporary inconvenience, PDPH can be debilitating in the short term. It can also be associated with chronic manifestations and serious complications.

Background: Rapid onset of epidural analgesia is an important concern for the parturient. Commonly, the local anaesthetic mixture is administered through the epidural catheter. Drugs administered through the epidural needle might decrease the onset time and enhance the spread of medication within the epidural space.
