To compare perioperative management and functional outcome of spinal anesthesia (SpA) to general anesthesia (GA) in high-risk patients treated for lower urinary tract symptoms (LUTS) with Holmium laser enucleation of the prostate (HoLEP).
In the current retrospective analysis, a propensity-score-matching of patients treated for LUTS with HoLEP (n=300) in SpA with ASA>2 (n=100), GA with ASA>2 (GA-high-risk) (n=100) or GA with ASA≤2 (GA-low-risk) (n=100) was performed. The impact of anesthesiologic mode on perioperative anesthesiologic outcome, early functional outcome and treatment related adverse events (according to Clavien Dindo), was evaluated.
Hypotensive episodes were significantly less frequent in the SpA-cohort (9%) compared to the GA-high-risk cohort (32%) and the GA low-risk cohort (22%) (each p<0.05 respectively). SpA-patients showed a significantly shorter median time in post anesthesia care unit (PACU-time: 135min; 120-166.5) compared to GA-high-risk patients (186min; 154-189.5), with significant less referrals to Intermediate care unit (ICU) (1% vs. 9 %); (each p<0.05). PACU-time (99min) and ICU referrals (0%) for GA-low-risk were lower than for both other cohorts. Postoperative requirement for analgesics was significantly lower in the SpA-cohort (2%), compared to both GA-cohorts (74% and 61% respectively; p<0.05). No significant difference was found regarding early functional outcome or treatment related adverse events (AE) (p-range:0.201-1.000).
For patients undergoing HoLEP, SpA provides greater hemodynamic stability and allows faster overall postoperative recovery with preferable pain management. Yielding a comparable functional outcome, it is a safe and efficient alternative to GA in high-risk patients.
