Key result
Sugammadex reversal to 90% TOF was significantly faster under sevoflurane anesthesia (1.93 minutes) compared to isoflurane (3.06 minutes) and desflurane (2.65 minutes).
Why the study?
Does the choice of volatile anesthetic (isoflurane, sevoflurane, or desflurane) affect the reversal time of neuromuscular blockade by sugammadex in patients undergoing lower abdominal surgery?

Does the choice of volatile anesthetic (isoflurane, sevoflurane, or desflurane) affect the reversal time of neuromuscular blockade by sugammadex in patients undergoing lower abdominal surgery?
Absolute Event Rate: 1.93% vs 3.06%
p-value: p=<0.05
The reversal effect of sugammadex on neuromuscular blockade is faster in patients receiving sevoflurane compared to isoflurane or desflurane.
Sevoflurane may expedite sugammadex reversal versus other volatiles in abdominal surgery; extends RCT evidence on anesthetic interactions.
AbstractAim. In the present study, we aimed to compare the effects of isoflurane, sevoflurane and desflurane on the effect of sugammadex in reversing neuromuscular block. Methods. Ninty patients who were planned to undergo elective lower abdominal surgery under general anesthesia were included and were randomly assigned to 6 groups of 15. After intubation, group I1 and I2 patients received isoflurane, group S1 and S2 patients received sevoflurane and Group D1 and D2 patients received desflurane volatile anesthetic at 1.25 MAC. TOF values were recorded at the 10th, 20th, 30th, 60th and 90th minutes of the operation by an anesthetist blind to the groups. Group I1, S1 and D1 patients were given 2 mg kg-1 sugammadex and group I2, S2 and D2 patients were given neostigmine after the second response to TOF following the latest rocuronium dose was observed again. In each patient, the time elapsed between sugammadex administrations and 10%, 25% and 90% TOF ratio was recorded. Results. There was no difference among the groups in terms of the time elapsing to reach 10% TOF values while the times elapsing to reach 25% and 90% TOF were found to be the shortest in sevoflurane group and the longest in isoflurane group. Conclusion. We think that inhalation anesthetics used in general anesthetic practice, have different effects on the reversal action of sugammadex in neuromuscular blockade and that reversal effect of sugammadex is faster in patients receiving sevoflurane.Keywords: Sugammadex, train of four, isoflurane, desflurane, sevoflurane, rocuroniumÖzetAmaç. Bu çalışmada sugamadeksin nöromusküler blokör etkisini geri döndürücü etkisine isofluran, sevofluran ve desfluranın etkilerini kıyaslamayı amaçladık. Yöntem. Genel anestezi altında elektif alt batın operasyonu planlanan 90 hasta çalışmaya alındı ve rasgele 15 er kişilik 6 gruba ayrıldı. Entübasyondan sonra, grup I1 ve I2 hastalar izofluran, grup S1 ve S2 hastalarda sevofluran ve grup D1 ve D2 hastalarda desfluran volatil anestetik olarak 1.25 MAC den aldı. TOF değerleri gruplardan habersiz bir anestezist tarafından operasyonda 10, 20, 30, 60. ve 90. dakikalarda kaydedildi. I1, S1 ve D1 grubu hastalara son rokuronyum dozunun ardından TOF a alınan ikinci yanıtın tekrar gözelnmesi sonrası 2 mg kg-1 sugamadeks ve I2, S2 ve D2 grubu hastalarada yine aynı şekilde neostigmine verildi. Her hastaya, sugamadeks uygulanması ile % 10,% 25 ve% 90 TOF oranı arasındaki süre kaydedildi. Bulgular. Gruplar arasında TOF un %10 a ulaşmasına kadar geçen sure açısından fark bulunamazken TOF un % 90 a ulaşma süresi sevofluran grubunda kısa ve izofluran grubunda en uzun olduğu bulunmuştur. Sonuç. Genel anestezi pratiğinde kullanılan inhalasyon anesteziklerinin sugamamdeksin nöromusküler blokaj geri döndürücü etkinliğini farklı oranlarda etkilediğini ve sevofluran anestezisinde sugamadeksin geri döndürücü etkisinin en hızlı olduğunu düşünmekteyiz.

Düğer et al. (2013) conducted an RCT in Elective lower abdominal surgery under general anesthesia (n=90). Sugammadex (under sevoflurane anesthesia) vs. Sugammadex (under isoflurane or desflurane anesthesia) was evaluated on Time to reach TOF 90% (p=<0.05). Sugammadex reversal to 90% TOF was significantly faster under sevoflurane anesthesia (1.93 minutes) compared to isoflurane (3.06 minutes) and desflurane (2.65 minutes).
