Brief Summary

The Neutrophil to Lymphocyte Ratio (NLR) is a frequently used biomarker of the systemic inflammatory response and is considered one of the most sensitive markers of inflammation. Many studies have documented the association between the use of opioid drugs in the acute phase -as it can be considered the use during general anesthesia- and the increase of the NLR value. Such increase could determine a temporary phase of immunodepression in the immediate post operative period with consequent increase of the inflammatory state. This study intends to assess whether different anesthetic techniques can be associated with different variations of the intra-patient NLR value between pre- and post-surgery. Patient will be randomized to receive either local regional anesthesia protocols with thoracic wall blocks (PEC I and serratus plane block) associated with opioid-free general anesthesia (PECS + Opioid-free GA) or general anesthesia.

Outcome Measures

Primary Outcomes (1)

  • 24h NLR variation

    Intra-patient variation of the NLR value between the pre-operative and the first post-operative day

    Pre-operative and at 24 hours after the end of surgery

Secondary Outcomes (5)

  • 1h NLR variation

    Pre-operative, 1 hour and 24 hours after the end of surgery

  • Opioid consumption

    24 hours

  • Complication

    until hospital discharge, an average of 48 hours

  • Chronic pain

    3, 6 and 12 months after surgery

  • Change in the levels of circulating cytokines in the post-operative period (one hour and 24 hours after surgery), compared to the baseline pre-operative values, in the two arms

    24 hours

Study Arms (2)

PECS + Opioid-free GA

EXPERIMENTAL

Loco-regional anesthesia with PEC I and serratus plane block with an echoguided technique and opioid-free general anesthesia

Drug: MidazolamProcedure: PECSProcedure: Opioid-free general anesthesiaProcedure: Postoperative analgesia

GA

ACTIVE COMPARATOR

General anesthesia

Drug: MidazolamProcedure: General anesthesiaProcedure: Postoperative analgesia

Interventions

1-2 mg of Midazolam as premedication.

GAPECS + Opioid-free GA
PECSPROCEDURE

Loco-regional anesthesia: PEC I and serratus plane block with an echoguided technique. For the PEC I: infiltration of 10 ml of local anesthetic (Levobupivacaine 0.25% or Ropivacaine 0.5%) between the bands of the pectoralis major muscle and the small pectoralis muscle at the height of the third rib on the anterior axillary line. For the serratus plane block: identification of the fifth rib on the average axillary line and infusion of about 20 ml of local anesthetic (Levobupivacaine 0.25% or Ropivacaine 0.5%) between the bands of large dorsal muscle and of the anterior serratus muscle.

PECS + Opioid-free GA

Induction with Propofol 1.5-2 mg/kg; laryngeal mask for airway management after eventual administration of Rocuronium 0.6 mg/kg. Anesthesia will be maintained with Propofol in Target-Controlled Infusion (TCI) of 6 mcg/ml, subsequently modified to maintain a Bispectral Index (BIS) value between 40 and 60. Fentanyl 50ug in bolus IV, in case of mean arterial pressure or heart rate increase \>20%. In case of hypotension: 5mg ephedrine and infusion of 250 ml Lactated Ringer.

PECS + Opioid-free GA

Induction with Propofol 1.5-2 mg/kg; Fentanyl 1μg/kg; laryngeal mask for airway management after eventual administration of Rocuronium 0.6 mg/kg. Anesthesia will be maintained with Propofol in TCI of 6 mcg/ml, subsequently modified to maintain a BIS value between 40 and 60. Fentanyl 50ug in bolus IV, in case of mean arterial pressure or heart rate increase \>20%. In case of hypotension: 5mg ephedrine and infusion of 250 ml Lactated Ringer.

GA

Paracetamol 1000 mg every 8 hours for the first 24 hours, Ketorolac 30 mg in case of pain control failure (Numeric Rating Scale- NRS\>4) which can be administered every 8 hours at most (max 90 mg / 24 hours), Morphine 10-20 mg IV in 24 hours as rescue analgesia.

GAPECS + Opioid-free GA
