Case Reports
Lidocaine Infusion for the Treatment of Headache Associated With Subarachnoid Hemorrhage: A Case Report.
Headache after subarachnoid hemorrhage and corresponding craniotomy with aneurysm clipping can be severe and difficult to treat. Currently accepted analgesic therapies are often ineffective at treating the pain without incurring unacceptable side effects. ⋯ Opioid consumption fell to zero for both patients during lidocaine infusions without lidocaine toxicity. Moreover, after discontinuation of lidocaine infusions, both patients reported good pain control using only standard oral medications.

Bilateral Sphenopalatine Ganglion Block With Liposomal Bupivacaine Followed by Severe Hypertension: A Case Report.
We reviewed a case of bilateral sphenopalatine ganglion (SPG) blockade with liposomal bupivacaine for sinus surgery. The case was complicated by severe postoperative hypertension refractory to antihypertensives and needing intensive care unit (ICU) admission. ⋯ We discuss how local anesthetic spread beyond the SPG may have caused prolonged parasympathetic blockade and hypertension. Before approved indications are established, we recommend avoiding the use of liposomal bupivacaine in off-label settings when the function of bilateral autonomic structures could be affected.

The application of a surgical face mask over oxygen delivery devices is now a widespread recommendation in the setting of the Coronavirus disease pandemic. This addition is designed to reduce droplet spread, but this also changes the nature of these devices, and may alter the amount of oxygen delivered to a patient. This research investigated how placing a surgical face mask over both a simple plastic mask ("Hudson mask") and nasal cannula altered the concentration of available oxygen measured at the nares. ⋯ The addition of a surgical face mask over both nasal cannula and a Hudson mask resulted in an increased available oxygen concentration. This may be valuable where more advanced oxygen devices are not available, or alternatively providing adequate supplemental oxygen at lower flow rates and thus making critical savings in oxygen usage.
