Nitroglycerin versus milrinone for low central venous pressure in patients undergoing laparoscopic hepatectomy: a double-blinded randomized controlled trial. BMC Anesthesiol 2024; 24:244. [PMID: 39026144 PMCID: PMC11256614 DOI: 10.1186/s12871-024-02631-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2024] [Accepted: 07/10/2024] [Indexed: 07/20/2024] Open
Abstract
BACKGROUND Conventional anesthesia used to reduce central venous pressure (CVP) during hepatectomy includes fluid restriction and vasodilator drugs, which can lead to a reduction in blood perfusion in vital organs and may counteract the benefits of low blood loss. In this study, we hypothesized that milrinone is feasible and effective in controlling low CVP (LCVP) during laparoscopic hepatectomy (LH). Compared with conventional anesthesia such as nitroglycerin, milrinone is beneficial in terms of intraoperative blood loss, surgical environment, hemodynamic stability, and patients' recovery. METHODS In total, 68 patients undergoing LH under LCVP were randomly divided into the milrinone group (n = 34) and the nitroglycerin group (n = 34). Milrinone was infused with a loading dose of 10 µg/kg followed by a maintenance dose of 0.2-0.5 µg/kg/min and nitroglycerin was administered at a rate of 0.2-0.5 µg/kg/min until the liver lesions were removed. The characteristics of patients, surgery, intraoperative vital signs, blood loss, the condition of the surgical field, the dosage of norepinephrine, perioperative laboratory data, and postoperative complications were compared between groups. Blood loss during LH was considered the primary outcome. RESULTS Blood loss during hepatectomy and total blood loss were significantly lower in the milrinone group compared with those in the nitroglycerin group (P < 0.05). Both the nitroglycerin group and milrinone group exerted similar CVP (P > 0.05). Nevertheless, the milrinone group had better surgical field grading during liver resection (P < 0.05) and also exhibited higher cardiac index and cardiac output during the surgery (P < 0.05). Significant differences were also found in terms of fluids administered during hepatectomy, urine volume during hepatectomy, total urine volume, and norepinephrine dosage used in the surgery between the two groups. The two groups showed a similar incidence of postoperative complications (P > 0.05). CONCLUSION Our findings indicate that the intraoperative infusion of milrinone can help in maintaining an LCVP and hemodynamic stability during LH while reducing intraoperative blood loss and providing a better surgical field compared with nitroglycerin.

The role of gut barrier dysfunction in postoperative complications in liver transplantation: pathophysiological and therapeutic considerations. Infection 2024; 52:723-736. [PMID: 38324146 PMCID: PMC11143052 DOI: 10.1007/s15010-024-02182-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2023] [Accepted: 01/11/2024] [Indexed: 02/08/2024]
Abstract
PURPOSE Gut barrier dysfunction is a pivotal pathophysiological alteration in cirrhosis and end-stage liver disease, which is further aggravated during and after the operational procedures for liver transplantation (LT). In this review, we analyze the multifactorial disruption of all major levels of defense of the gut barrier (biological, mechanical, and immunological) and correlate with clinical implications. METHODS A narrative review of the literature was performed using PubMed, PubMed Central and Google from inception until November 29th, 2023. RESULTS Systemic translocation of indigenous bacteria through this dysfunctional barrier contributes to the early post-LT infectious complications, while endotoxin translocation, through activation of the systemic inflammatory response, is implicated in non-infectious complications including renal dysfunction and graft rejection. Bacterial infections are the main cause of early in-hospital mortality of LT patients and unraveling the pathophysiology of gut barrier failure is of outmost importance. CONCLUSION A pathophysiology-based approach to prophylactic or therapeutic interventions may lead to enhancement of gut barrier function eliminating its detrimental consequences and leading to better outcomes for LT patients.

Cardiac Radiofrequency Ablation Exacerbates Myocardial Injury through Pro-Inflammatory Response and Pro-Oxidative Stress in Elderly Patients with Persistent Atrial Fibrillation. Curr Vasc Pharmacol 2024; 22:137-152. [PMID: 38213173 DOI: 10.2174/0115701611257644231215071611] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2023] [Revised: 10/18/2023] [Accepted: 12/05/2023] [Indexed: 01/13/2024]
Abstract
BACKGROUND There is a need to assess myocardial damage after radiofrequency ablation of the pulmonary veins (PV) for persistent atrial fibrillation (PAF) in elderly patients. OBJECTIVE To evaluate oxidative stress, inflammatory response and myocardial damage in elderly patients with PAF after radiofrequency ablation of the PV. METHODS High-sensitivity troponin T (hsTnT), malondialdehyde-modified low-density lipoprotein (MDA-LDL), acrolein (ACR), lipid hydroperoxide (LHP), toll-like receptor 4 (TLR4), soluble growth stimulation expressed gene 2 (sST2), angiotensin II (Ang II) and myocardial blood flow (MBF) were determined before ablation and at 1, 3 and 5 months after radiofrequency ablation. RESULTS The levels of hsTnT, MDA-LDL, ACR, LHP, TLR4, sST2 and Ang II were increased 3 months after ablations compared with before ablation and 1 month after ablation, respectively (P<0.001); they were further increased at 5 months after ablation compared with the 1- and 3-month groups, respectively (P<0.001). MBF was decreased in the 3 months group after ablations compared with before ablation and 1-month after ablation, respectively (P<0.001), and was further decreased in 5-months after ablations compared with 1-month and 3-month groups, respectively (P<0.001). Patients with epicardial monopolar radiofrequency ablation had higher levels of hsTnT, MDA-LDL, ACR, LHP, TLR4, sST2, Ang II and lower MBF than patients with endocardial monopolar and bipolar radiofrequency ablations, respectively (P<0.001). CONCLUSION Monopolar radiofrequency ablation method could result in more myocardial injury than bipolar radiofrequency ablation. Oxidative stress and inflammatory response may be involved in cardiac radiofrequency ablation-induced myocardial injury, resulting in myocardial ischemia in elderly patients with PAF.

Abstract
INTRODUCTION Liver resection carries a high risk for extensive bleeding and need for blood transfusions, which is associated with significant negative impact on outcome. In malignant disease, the most common indication for surgery, it also includes increased risk for recurrence of cancer. Argipressin decreases liver and portal blood flow and may have the potential to reduce bleeding during liver surgery, although this has not been explored. METHOD AND ANALYSIS ARG-01 is a prospective, randomised, placebo-controlled, double-blinded study on 248 patients undergoing liver resection at Sahlgrenska University Hospital, Sweden. Patients will be randomised to one of two parallel groups, infusion of argipressin or normal saline administered peroperatively. The primary endpoint is peroperative blood loss. Secondary outcomes include need for blood transfusion, perioperative variables, length of hospital stay, the inflammatory response, organ damage markers and complications at 30 days. ETHICS AND DISSEMINATION The study is enrolling patients since March 2022. The trial is approved by the Swedish Ethical Review Authority (Dnr 2021-03557) and the Swedish Medical Product Agency (Dnr 5.1-2021-90115). Results will be announced at scientific meetings and in international peer-reviewed journals. TRIAL REGISTRATION NUMBER ClinicalTrials.gov, NCT05293041 and EudraCT, 2021-001806-32.

Effects of targeted mild hypercapnia versus normocapnia on cerebral oxygen saturation in patients undergoing laparoscopic hepatectomy under low central venous pressure: a prospective, randomized controlled study. BMC Anesthesiol 2023; 23:257. [PMID: 37525100 PMCID: PMC10388477 DOI: 10.1186/s12871-023-02220-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2023] [Accepted: 07/26/2023] [Indexed: 08/02/2023] Open
Abstract
BACKGROUND Laparoscopic hepatectomy under low central venous pressure (LCVP) is associated with intraoperative organ hypoperfusion, including cerebral hypoperfusion. We hypothesized that a ventilation strategy designed to achieve targeted mild hypercapnia (TMH) (end-tidal carbon dioxide partial pressure [PetCO2] of 45 ± 5 mmHg) rather than targeted normocapnia (TN) (PetCO2 of 30 ± 5 mmHg) would increase regional cerebral oxygen saturation (rSO2) during laparoscopic hepatectomy under LCVP. METHODS Eighty patients undergoing laparoscopic hepatectomy under LCVP were randomly divided into the TMH group (n = 40) and the TN group (n = 40). Mechanical ventilation was adjusted to maintain the PetCO2 within the relevant range. Cerebral oxygenation was monitored continuously using the FORE-SIGHT system before anesthetic induction until the patient left the operating room. Patient and surgical characteristics, rSO2, intraoperative hemodynamic parameters (CVP, mean artery blood pressure [MAP], and heart rate), PetCO2, intraoperative blood gas analysis results, and postoperative complications were recorded. RESULTS No significant differences were observed in CVP, MAP, and heart rate between the two groups during surgery. The rSO2 was significantly lower in the TN group on both the left and right sides during the intraoperative period (P < 0.05), while the TMH group had a stable rSO2. In the TN group, the mean rSO2 decreased most during liver parenchymal transection when compared with the baseline value (P < 0.05). The mean (standard deviation) percentage change in rSO2 from baseline to parenchymal transection was - 7.5% (4.8%) on the left and - 7.1% (4.6%) on the right. The two groups had a similar incidence of postoperative complications (P > 0.05). CONCLUSION Our findings demonstrate that rSO2 is better maintained during laparoscopic hepatectomy under LCVP when patients are ventilated to a PetCO2 of 45 ± 5 mmHg (TMH) than a PetCO2 of 30 ± 5 mmHg (TN).
