E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Does periferal ropivacaine infusion reduce pain after above knee amputation in patients with atheros sclerosis obliterans |
Vähentääkö perifeerinen ropivakaiini-infuusio kipua reisiamputaation jälkeen ASO tautia sairastavilla potilailla |
|
E.2.2 | Secondary objectives of the trial |
Does periferal ropivacaine infusion reduce opioid consumption and opioid reverse affects and prolonged postoperative pain after above knee amputation in patients with atheros sclerosis obliterans |
Vähentääkö perifeerinen ropivakaiini-infuusio opioidien tarvetta ja opioidien aiheuttamia haittavaikutuksia ja pitkittynyttä leikkauksen jälkeistä kipua reisiamputaation jälkeen ASO tautia sairastavilla potilailla |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Patients presenting for above knee amputation for artheroschlerosis willing to participate, able to give informed consent, able to asses pain using verbal rating scale and assessed to be medically stable so that life expectancy exceeds two weeks as assessed by recruiting anesthesiologist. |
Tutkimukseen rekrytoidaan valtimokovettumataudin aiheuttaman iskemian takia reisiamputaatioon tulevia potilaita, jotka kykenevät antamaan tietoon perustuvan suostumuksen ja ovat halukkaita osallistumaan tutkimukseen, kykenevät arvioimaan kipuaan viisiportaisella sanallisella asteikolla (VRS), ja ovat yleistilaltaan vakaita niin että hoitavan anestesiologin kliinisen arvion mukaan todennäköisesti odotettavissa oleva elinikä on ainakin 2 viikkoa. |
|
E.4 | Principal exclusion criteria |
Allergy to amide local anesthetics, operating surgeon unable to insert the catheter as defined in the protocol, planned epidural postoperative pain management. |
Ekskluusiokriteereinä ovat allergia amidipuudutteille, päivystävän kirurgin riittämätön taito asettaa puudutuskatetri tutkimuksessa sovitulla tavalla tai potilaalle suunniteltu epiduraalinen kivun hoito amputaatioleikkauksen jälkeen. |

E.5 End points |
E.5.1 | Primary end point(s) |

Tutkimuksen päälopputulosmuuttuja on leikatun alaraajan amputaatiotyngän kipu levossa mitattuna. Kipua mitataan VRS-asteikolla |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Days 1-5 after operation. |
1-5 postoperatiivisena päivänä. |
|
E.5.2 | Secondary end point(s) |

Tutkimuksessa seurataan toissijaisina lopputulosmuuttujina tyngän kipua 1, 3 ja 12 kk leikkauksen jälkeen ja aaveraajan kipua 1-5 vrk ja 1, 3 ja 12 kk leikkauksen jälkeen samalla asteikolla, opioidikipulääkkeiden tarvetta 1-5 päivää leikkauksen jälkeen ja haittavaikutuksia (haavainfektiot, uusintaleikkaukset, muut merkittävät haittatapahtumat). |
