E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
The aim of this study is to quantify peak and mean venous serum concentrations of ropivacaine after ultrasound guided Pecs II block with 2.5mg/kg ropivacaine diluted to 30ml. |
Het doel van dit onderzoek is om de piek- en gemiddelde veneuze serumconcentraties van ropivacaïne te kwantificeren na Pecs II-blok met echografie met 2,5 mg / kg verdunde ropivacaïne tot 30 ml. |
|
E.1.1.1 | Medical condition in easily understood language |
We want to investigate in what amount the injected local anesthesia of a Pecs II block drains away to the bloodstream and if that amount reaches the maximum allowed dose or not. |
We willen onderzoeken in welke hoeveelheid de geïnjecteerde lokale anesthesie van een Pecs II-blok wegvloeit naar de bloedbaan en of die hoeveelheid de maximaal toegestane dosis overschrijdt of niet. |

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
In order to be eligible to participate in this study, a subject must meet all of the following criteria: (1) Age 18 or older (2) BMI between 17 and 35kg/m2, (3) scheduled for elective unilateral mastectomy or tumorectomy with sentinel node resection or axillary clearance, and (4) written informed consent. |
Om in aanmerking te komen om deel te nemen aan dit onderzoek, moet een proefpersoon aan alle volgende criteria voldoen: (1) Leeftijd 18 of ouder (2) BMI tussen 17 en 35kg / m2, (3) gepland voor electieve unilaterale mastectomie of tumorectomie met schildwachtklierresectie of okselevidemment, en (4) schriftelijke geïnformeerde toestemming. |
|
E.4 | Principal exclusion criteria |
Patients with (1)known allergies or sensitivity to local anaesthesia, or with (2) a BMI less than 17 or more than 35 kg/m2, (3) who are pregnant, (4) who have renal (GFR < 60ml/min) and/or hepatic impairment (end-stage liver disease that compromises normal hepatic drug metabolism) will be excluded. Given our inclusion and exclusion criteria, minors and subjects not capable of giving informed consent will be excluded from participation in the study. |
Patiënten met (1) bekende allergieën of gevoeligheid voor lokale anesthesie, of met (2) een BMI lager dan 17 of meer dan 35 kg / m2, (3) die zwanger zijn, (4) die nier hebben (GFR <60ml / min) ) en / of leverinsufficiëntie (eindstadium leverziekte die het normale metabolisme van de lever in gevaar brengt) zullen worden uitgesloten. Gezien onze opname- en uitsluitingscriteria zullen minderjarigen en personen die geen geïnformeerde toestemming kunnen geven, worden uitgesloten van deelname aan het onderzoek. |

E.5 End points |
E.5.1 | Primary end point(s) |
The aim of this study is to quantify peak and mean venous serum concentrations of ropivacaine after a Pecs II block with 2.5mg/kg ropivacaine diluted to 30ml. |
Het doel van dit onderzoek is om de piek- en gemiddelde veneuze serumconcentraties van ropivacaïne te kwantificeren na een Pecs II-blok met 2,5 mg / kg verdunde ropivacaïne tot 30 ml. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Ten blood samples will be obtained. Two blood samples will be obtained immediately after placement of the Pecs II block as one of these sample will be used to determine albumin and alpha-1-glycoprotein levels. The eight other blood sample will be obtained at 10, 20, 30, 45, 60, 90 and 120 minutes and at 4 hours after performing the Pecs II block. |
Er zullen tien bloedstalen worden verkregen. Twee bloedstalen worden direct na plaatsing van het Pecs II-blok verkregen, omdat een van deze stalen zal worden gebruikt om albumine- en alfa-1-glycoproteïne gehalten te bepalen. De acht andere bloedstalen wordt verkregen na 10, 20, 30, 45, 60, 90 en 120 minuten en 4 uur na het uitvoeren van het Pecs II-blok. |
