4. Goals of General Anesthesia
• Hypnosis (unconsciousness)
• Amnesia
• Analgesia
• Immobility/decreased muscle tone
– (relaxation of skeletal muscle)
• Inhibition of nociceptive reflexes MAC
• Reduction of certain autonomic reflexes
– (gag reflex, tachycardia, vasoconstriction) MAC-BAR
( blockade adrenergic response)

7. Opioid in Balanced Anesthesia
• Furthermore in one study of 150 elective ASA I-III, surgical patients aged
65-92 years old showed that:
– Fentanyl reduced the rises in systolic, diastolic and mean arterial
pressures, heart rate, and rate pressure product (P < 0.05)
– Fentanyl decreased the incidence of marked fluctuations in
hemodynamic variables, often seen in geriatric patients (P < 0.05).

9. FARMAKOEKONOMI
• Biaya opersional rumah sangat meningkat
terutama kamar operasi
• Data biaya dikeluarkan RS 6% obat
anestesi dari seluruh pembelian obat di RS
Dari 6% 20% adalah obat inhalasi.
• Mulai dikembangkan Farmakoekonomi
10. FARMAKOEKONOMI
Farmakoekonomi adalah subdisiplin ilmu ekonomi
kesehatan yang membandingkan biaya dan
efektivitas suatu obat terhadap obat lain serta
melakukan analisis keduanya
Analisa ini untuk memberikan pelayanan kesehatan
berdasarkan nilai yaitu mendapatkan hasil yang
terbaik dengan biaya yang murah
Telah berkembang dinegara maju seperti Amerika
serikat, Jerman dan Australia
11. The Role of Fentanyl in Balance Anesthesia
The Potentiation of Anesthetic Agents with Fentanyl
• Rapid induction
• Analgesia
• Inhibition of nociceptive reflexes
• Farmakoekonomi / cost effective
• Decrease the MAC
• Reduction of certain autonomic reflexes
– (gag reflex, tachycardia, vasoconstriction)
12. Fentanyl
• Penggunaan paling sering dari fentanyl adalah sebagai agen
analgesik selama pemberian balanced anesthesia. Dosis
fentanyl sebesar 0.5 – 2.5 mcg/kg dilakukan secara intermiten
disesuaikan dengan intensitas pembedahan dan dapat diulang
kurang lebih setiap 30 menit.
• Dosis alternatif, pemberian loading dose 5-10 mcg/kg dan
infus kontinu fentanyl pada kecepatan antara 2-10
mcg/kg/jam dapat direkomendasikan.
13. Fentanyl
• Onset kerja fentanyl singkat, namun peak effect
tercapai dalam waktu 5 menit.
• Pada praktek klinis secara umum, dosis fentanyl
yang digunakan sebelum dimulai induksi adalah
1,5 sampai 5 mcg/kg.
• Titrasi fentanyl dilakukan sekitar 3 menit sebelum
dilakukan laringoskopi karena efek puncaknya
yang mengalami perlambatan sekitar 3-5 menit
untuk mendapatkan efek yang maksimal.
15. Adverse Reactions:
MS: Muscle rigidity, particularly involving
muscles of respiration.
CV: Bradydysrhythmias (common) or
tachydysrhythmias, hypotension,
orthostatic hypotension
Resp: Respiratory depression (common) or arrest.
CNS: Pupillary constriction. Sedation
GI: Nausea and Vomiting
Derm: Histamine release may cause local or
general urticaria

51. Conclusions
• Fentanyl produces a reduction in the minimum alveolar
concentarion ( MAC) of isoflurene, sevoluren and
desflurance
• Minimum alveolar concentarion (MAC) and Minimum
alveolar concentarion blockade adrenergic response
(MEC BAR) MAP and heart rate decreased similarly
with creasing concentrations of fentanyl in plasma.
• Somatic and symphatetic responses to surgycal incision
are clinical end points for assessing depth of anesthesia
• The intraction of fentanyl on the Cp50 of Propofol and
Thiopental.
53. • Isoflurane consumption was total of isoflurane
for the whole operation (ml) and calculated
with the following equation :
Vol : C x Flow O2 x 1/ Vapour pressure x T
C:Mean concentration of the anesthetic volatile agent (vol%, T; Duration
of the operation, Flow O2: O2 flow (l/mnt), (Vapour pressure isoflurane :
240 )
