On-Q ® PainBuster ® Smärta system bör införas över hela snittet i subkutana vävnaden strax före tillslutning av sår. Detta underlättar strävan via trevägskran vid bestämda tidpunkter. On-Q ®-system levererar kontinuerligt koksaltlösning subkutant i såret med en hastighet av 2 ml / h. Detta förhindrar att katetern koagulering och förbättrar tillförlitligheten i systemet för att producera exsudat prover. Om aspiration av sårvätska är svårt (ca 5% av fallen), överväga att ändra motivets position (t.ex., sitter patie...

 was added. The abstract was updated to :
We describe a methodology by which we are able to collect and measure inflammatory and nociceptive biochemical mediators at the surgical wound site. Collecting site-specific biochemical markers allows us to evaluate the relationship between surgical wound and serum levels; determine any associations between mediator release, pain and analgesic consumption; and evaluate the effect of systemic and peripheral drug administration on surgical wound biochemistry.
This methodology has been applied to healthy women undergoing elective cesarean delivery with spinal anesthesia. Wound exudate and serum mediators, in conjunction with pain scores and analgesics consumption were measured at 1, 6, 24, and 48 hours post-cesarean delivery. Biochemical mediators that were detected included IL-1&beta;, IL-2, IL-4, IL-6, IL-7, IL-8, IL-10, IL-12, IL-13, IL-17, TNF&alpha;, INF&gamma;, G-CSF, GM-CSF, MCP-1 and MIP-1&beta;, nerve growth factor (NGF), prostaglandin E2 (PG-E2) and substance P. We found no correlations between wound and serum cytokines concentrations or time-release profiles (J Pain. 2008 Jul 9(7):650-7). This article describes and demonstrates the feasibility of collecting and assaying nociceptive and inflammatory mediators in surgical wounds at specific time points. The lack of significant correlations between serum and wound levels shows the importance of determining site-specific release if surgical wounds and localized pathologies are to be studied.

The objectives of this study were to test the feasibility of collecting and measuring inflammatory and nociceptive biochemical mediators at the surgical site; to evaluate the relationship between wound and serum levels; and to determine any associations between mediator release, pain and analgesic consumption post-cesarean delivery. Twenty healthy women undergoing elective cesarean delivery with spinal anesthesia were enrolled. Wound exudate and serum mediators, pain scores and analgesics consumption were measured at 1, 6, 24, and 48 hours post-cesarean. In wound exudate, 19 out of 20 mediators were reliably detected including IL-1&beta;, IL-2, IL-4, IL-6, IL-7, IL-8, IL-10, IL-12, IL-13, IL-17, TNF&alpha;, INF&gamma;, G-CSF, GM-CSF, MCP-1 and MIP-1&beta;, nerve growth factor (NGF), prostaglandin E2 (PG-E2) and substance P. Wound PG-E2 and various cytokines peaked early, whereas NGF showed a more delayed release. There were no correlations between the concentration versus time profile of wound and serum cytokines. This study demonstrates the feasibility of collecting and measuring nociceptive and inflammatory mediators in surgical wounds at specific time points. The lack of significant correlations between wound and serum levels emphasizes the importance of determining site-specific release if localized pathologies are to be studied.

collecting and measuring nociceptive and inflammatory mediators in surgical wounds 

Målen för denna studie var att testa möjligheterna att samla in och mäta inflammatoriska och nociceptiv biokemiska mediatorer i operationsområdet, för att utvärdera förhållandet mellan såret och serum, och för att fastställa eventuella samband mellan medlaren release, smärta och smärtstillande konsumtion efter kejsarsnitt leverans. Tjugo friska kvinnor som genomgår elektiv kejsarsnitt med spinal anestesi inkluderades. Sårvätska och serum medlare, poäng smärta och analgetika konsumtion mättes vid 1, 6, 24 och 48 timmar efter kejsarsnitt. I sårvätska, var 19 av 20 medlare upptäckas tillförlitligt inklusive IL-1β, IL-2, IL-4, IL-6, IL-7, IL-8, IL-10, IL-12, IL-13, IL -17, TNF, INFγ, G-CSF, GM-CSF, MCP-1 och MIP-1β, nerv tillväxtfaktor (NGF), prostaglandin E2 (PG-E2) och substans P. Wound PG-E2 och olika cytokiner nådde tidigt , medan NGF visade en mer fördröjd frisättning. Det fanns inga samband mellan koncentrationen mot tiden profil sår och serum cytokiner. Denna studie visar på möjligheterna att samla in och mäta nociceptiv och inflammatoriska mediatorer i kirurgiska sår vid specifika tidpunkter. Avsaknaden av signifikanta korrelationer mellan såret och serum betonar vikten av att fastställa platsspecifika utsläppet om lokaliserade sjukdomstillstånd ska studeras.
