Bilateral subgaleal hematoma after a robot-assisted radical prostatectomy: an uncommon complication.

Robot-assisted radical prostatectomy is a relatively recent technique. Its advantages include less invasiveness and better pain management, but has specific anesthesia requirements, such as steep Trendelenburg position and pneumoperitoneum. Mild complications are common, e.g., transient hypotension or soft tissue edema. We present a case of a 62-year old male who developed subgaleal hematoma associated with transient neurologic impairment after surgery. Jugular vein insufficiency was suspected as the most likely cause. The patient recovered fully. Robot-assisted radical prostatectomy can be a challenging procedure due to the anesthesia requirements, but most complications are mild and transient. However, patients should be carefully assessed before surgery. We identified potential factors that may have led to this complication: the abnormal prolonged surgical time, the steep Trendelenburg, a non-assessed jugular vein insufficiency, and/or patient`s obesity.

La prostatectomía robótica radical es una técnica relativamente reciente. Sus ventajas son una menor invasividad y mejor control del dolor. Tiene algunas peculiaridades anestésicas, como Trendelenburg extremo y neumoperitoneo. Son frecuentes las complicaciones leves, como la hipotensión transitoria o el edema de partes blandas. Presentamos el caso de un varón de 62 años que desarrolló un hematoma subgaleal asociado a deterioro neurológico transitorio tras la intervención. Se sospechó como causa más probable una incompetencia venosa yugular. El paciente se recuperó completamente.La prostatectomía robótica radical puede ser un reto debido a los requisitos anestésicos, pero la mayoría de las complicaciones son leves y transitorias. No obstante, los pacientes deben ser estudiados cuidadosamente antes de la intervención. En este caso podemos encontrar varios factores que pueden haber influido, como el tiempo quirúrgico anormalmente prolongado, el Trendelenburg extremo, una insuficiencia de la vena yugular no evaluada y/o la obesidad del paciente.(AU)

Effect of sugammadex on processed EEG parameters in patients undergoing robot-assisted radical prostatectomy.

BACKGROUND: Sugammadex has been associated with increases in the bispectral index (BIS). We evaluated the effects of sugammadex administration on quantitative electroencephalographic (EEG) and electromyographic (EMG) measures. METHODS: We performed a prospective observational study of adult male patients undergoing robot-assisted radical prostatectomy. All patients received a sevoflurane-based general anaesthetic and a continuous infusion of rocuronium, which was reversed with 2 mg kg-1 of sugammadex i.v. BIS, EEG, and EMG measures were captured with the BIS Vista™ monitor. RESULTS: Twenty-five patients were included in this study. Compared with baseline, BIS increased at 4-6 min (ß coefficient: 3.63; 95% confidence interval [CI]: 2.22-5.04; P<0.001), spectral edge frequency 95 (SEF95) increased at 2-4 min (ß coefficient: 0.29; 95% CI: 0.05-0.52; P=0.016) and 4-6 min (ß coefficient: 0.71; 95% CI: 0.47-0.94; P<0.001), and EMG increased at 4-6 min (ß coefficient: 1.91; 95% CI: 1.00-2.81; P<0.001) after sugammadex administration. Compared with baseline, increased beta power was observed at 2-4 min (ß coefficient: 93; 95% CI: 1-185; P=0.046) and 4-6 min (ß coefficient: 208; 95% CI: 116-300; P<0.001), and decreased delta power was observed at 4-6 min (ß coefficient: -526.72; 95% CI: -778 to -276; P<0.001) after sugammadex administration. Neither SEF95 nor frequency band data analysis adjusted for EMG showed substantial differences. None of the patients showed clinical signs of awakening. CONCLUSIONS: After neuromuscular block reversal with 2 mg kg-1 sugammadex, BIS, SEF95, EMG, and beta power showed small but statistically significant increases over time, while delta power decreased.
