A&A practice

Rectus sheath blocks can provide analgesia for upper abdominal midline incisions. These blocks can be placed on patients who are anticoagulated, supine, and under general anesthesia. ⋯ Here we characterize a hypoechoic triangle with sonography, an anatomic space between adjacent rectus abdominis segments that can be accessed for easier needle tip and catheter placement. This approach could reduce reliance on hydrodissection to correctly identify the potential space and instead improve block efficacy by offering providers a discrete target for local anesthesia.

Dorsal column (dcSCS) and dorsal root ganglion stimulation (DRG-S) complications are similar, typically related to placement and device failure. We present the first case of tinnitus after DRG-S implantation. The patient presented with complex regional pain syndrome (CRPS) type 2. ⋯ After permanent implantation, she reported persistent, intolerable left-sided tinnitus. Tinnitus can be modulated by secondary somatosensory inputs to the cochlear nucleus from the dcSCS. Therefore, lumbosacral DRG-S stimulating distal sensory neurons leading to tinnitus is a feasible complication.

This is the first case report describing an aryepiglottic cyst resulting in critical airway compromise after an uneventful tracheal intubation. We present the case of a 55-year-old woman who developed acute dyspnea and stridor several hours after the surgery. She was found to have significant upper airway obstruction owing to a large left aryepiglottic cyst with a ball-valve effect.

Spondylometaphyseal dysplasia (SMD) is a rare genetic disorder affecting skeletal growth and development presenting anesthesiologists with many perioperative challenges. We present a case of a patient found to have multilevel tracheal stenosis due to twisting and folding of his trachea. ⋯ Structural and functional abnormalities of the trachea have not been reported in SMD. This is the first description of a patient with SMD with severe multilevel tracheal disease requiring tracheal reconstructive surgery.

Case Reports
Cardiac Tamponade Caused By Carbon Dioxide Insufflation During Robot-Assisted Thoracic Surgery: A Case Report.
Various complications can occur during robot-assisted thoracic surgery for mediastinal tumors owing to carbon dioxide (CO2) insufflation. This study reports the case of a 43-year-old woman who underwent robot-assisted surgery for an anterior mediastinal tumor with the subxiphoid approach. ⋯ Cardiac tamponade due to entry of CO2 gas into the pericardial cavity was suspected. A deliberate incision was made in the right pericardium, ultimately resolving the cardiac tamponade and substantially improving the patient's blood pressure.
