Favored induction agents : IV propofol, IV or IM ketamine, and inhalational sevoflurane Thiopental dapat menginduksi terjadinya bronkospasme akibat keluarnya histamin Etomidate Vasodilatasi Sevoflurane, isoflurane, and halothane are potent bronchodilators, decrease airway responsiveness, and can attenuate bronchospasm D esflurane pungency and airway irritant Nitrous oxide may be used in patients, but it does not have bronchodilatory effects. If muscle relaxants are needed, consider the use of agents that will not require antagonism with anticholinesterase agents, because the muscarinic properties of these antagonist drugs can promote bronchospasm Dexmedetomidine has been effectively used in asthmatics. Synthetic opioids, with the exception of meperidine, offer pain relief with minimal risk of histamine release.5 Intraoperative management E

Intraoperatif Refleks bronkospasme dapat ditumpulkan dengan beberapa cara : Mendalamkan anestesi dengan cara memberikan ventilasi selama 5 menit dengan 2-3 MAC Pemberian lidokain intravena atau intratrakeal 1-2 mg/kg. perlu menjadi perhatian bahwa lidokain intratrakea dapat menginisiasi bronkospasme apabila dosis induksi tidak adekuat . Dalam sumber lain IV lidocaine (1–1.5 mg/kg) Inhalational albuterol (2–4 puffs via metered-dose inhaler) 15 minutes sebelum induksi Pemberian agen antikolinergik dapat menghambat refleks bronkospasme namun memiliki efek samping takikardi Butterworth JF, Mackey DC, Wasnick JD.

Intraoperatif Pembiusan regional masih menjadi pilihan dibandingkan pembiusan umum Ventilasi dan oksigenasi arteri dipertahankan dengan penggunaan ventilator mekanik Pada pasien asma, laju inspirasi perlahan akan mengoptimalkan ventilasi dan perfusi Pemanjangan waktu ekshalasi dapat mencegah air trapping Pemberian cairan adekuat selama perioperatif membantu hidrasi dan menurunkan viskositas sekresi lendir Butterworth JF, Mackey DC, Wasnick JD.

Alternatives to intubation Avoid tracheal instrumentation by administering general anesthesia by mask or by laryngeal mask airway (LMA), local anesthesia , and regional anesthesia . Sedation is safe in asthmatic patients, as is the appropriate use of IV and neuraxial narcotic agents to treat pain. G
