 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 

Gli obiettivi di questo studio sono stati per testare la fattibilità della raccolta e misurazione dei mediatori biochimici infiammatori e nocicettivi nel sito chirurgico, per valutare la relazione tra ferita e livelli sierici, e per determinare eventuali associazioni tra rilascio mediatore, il dolore e il consumo di analgesici post-cesareo consegna. Venti donne sane in fase di consegna elettiva cesareo con anestesia spinale sono stati arruolati. Essudato e mediatori del siero, i punteggi del dolore ed il consumo di analgesici sono stati misurati ad 1, 6, 24, e 48 ore post-parto cesareo. In essudato, 19 su 20 mediatori erano rilevata con certezza tra cui IL-1β, IL-2, IL-4, IL-6, IL-7, IL-8, IL-10, IL-12, IL-13, IL -17, TNFa, INFγ, G-CSF, GM-CSF, MCP-1 e MIP-1β, fattore di crescita nervosa (NGF), prostaglandine E2 (PG-E2) e sostanza P. ferita PG-E2 e varie citochine raggiunto l&#39;apice all&#39;inizio , mentre NGF ha mostrato una versione più ritardato. Non ci sono state correlazioni tra la concentrazione rispetto al profilo temporale delle ferite e delle citochine sieriche. Questo studio dimostra la fattibilità della raccolta e misurazione dei mediatori infiammatori nocicettivo e nelle ferite chirurgiche in punti temporali specifici. La mancanza di correlazioni significative tra ferita e livelli sierici sottolinea l&#39;importanza di determinare site-specific di rilascio se patologie localizzate sono da studiare.
