Perioperative haemodynamic monitoring

Junhui Zhao, Chuixian Zhou
The aim of the present study was to analyze the protective and hemodynamic effects of dexmedetomidine in hypertensive cerebral hemorrhage (HCH) patients during perioperative period. In total, 50 HCH patients were selected and randomly divided into two groups, one group was administered with dexmedetomidine and the other groups with midazolam. The mean arterial pressure (MAP), heart rate (HR) and blood oxygen saturation (SpO2) were monitored in the two groups of patients before and during the operation. The MAP, HR, SpO2 and PETCO2 recorded 5 min after admission into the operation room was considered T1, the same parameters recorded 10 min after drug administration were considered T2, just after starting the operation were considered T3 and 30 min after start of operation were considered T4...

The elderly population is rapidly growing and particularly diverse. Ageing leads to reduced organ function and a decline in physiologic reserve. Elderly patients are characterised by great inter-individual variability in physiological function with a high prevalence of chronic disease. In general, older patients have a higher risk of postoperative adverse outcomes, and frailty is a very important risk factor. This review article aims to provide a practical guide to anaesthetic management of the elderly surgical patient...

Basic haemodynamic monitoring is an essential part of the anaesthesia work place. This includes Monitoring of ECG, blood pressure and pulse oximetry. For early assessement of perioperative complications every patient should have a basic haemodynamic monitoring, independant of current health status or the type of anaesthesia applied. Knowledge of function, principles and limitations ais necessary for proper interpretation of the measured values. Here, we describe the function and application of ECG, non - invasive intermittent blood pressure and pulse oximetry in the perioperative setting...

BACKGROUND: Intraoperative haemodynamic monitoring is carried out in high-risk surgical patients, often using invasive methods, including pulmonary artery catheterisation. Early goal-directed therapy in high-risk surgical patients reduces tissue hypoxia, organ failure and improves outcomes. Significant maternal morbidity arises as a result of perioperative haemorrhage. At present, heart rate and brachial blood pressure are used as proxy markers to aid in fluid resuscitation, however, we know that these exhibit minimal change during early stages of shock, and are poor indicators of the adequacy of therapeutic intervention...

The oesophageal Doppler (OD) is a minimally invasive haemodynamic monitor used in the surgical theatre and the ICU. Using the OD, goal-directed therapy (GDT) has been shown to reduce perioperative complications in high-risk surgical patients. However, most GDT protocols currently in use are limited to stroke volume optimisation. In the present manuscript, we examine the conceptual models behind new OD-based measurements. These would provide the clinician with a comprehensive view of haemodynamic pathophysiology; including pre-load, contractility, and afterload...

Over the past decades, there has been considerable progress in the field of less invasive haemodynamic monitoring technologies. Substantial evidence has accumulated, which supports the continuous measurement and optimization of flow-based variables such as stroke volume, that is, cardiac output, in order to prevent occult hypoperfusion and consequently to improve patients' outcome in the perioperative setting. However, there is a striking gap between the developments in haemodynamic monitoring and the increasing evidence to implement defined treatment protocols based on the measured variables, and daily clinical routine...

BACKGROUND: Atherosclerosis of the carotid artery is a major source of stroke. In some cases, atherosclerosis occurs at several positions within the carotid artery. Carotid endarterectomy (CEA) in combination with retrograde balloon angioplasty and stenting of a brachiocephalic or common carotid artery stenosis has been described as efficacious and safe procedure to prevent stroke in these cases. The aim of this study was to analyze the impact of anesthetic techniques on hemodynamic factors, operation time, duration of clamping, and postoperative pain...

BACKGROUND: The delivery of cardiac patients is a challenge for the anaesthesiologist, to whom the welfare of both the mother and the foetus is a main issue. In case of caesarean section, advanced monitoring allows to optimize haemodynamic condition and to improve morbidity and mortality. OBJECTIVE: To describe the use of pulse contour analysis calibrated by Trans-pulmonar thermodilution (Picco Plus(®)) for the perioperative management of a caesarean section in a patient with severe cardiomyopathy...

BACKGROUND: Intraoperative use of oesophageal Doppler (OD) was associated with improved postoperative outcomes through the optimization of perioperative fluid management. We studied the effect on haemodynamics of a goal-directed fluid management approach, guided by OD, during elective spine surgery in the prone position. METHODS: Intraoperative fluid and vasopressor administration were directed according to one of two randomly chosen decision-making algorithms driven by either OD (OD group; n=33 patients) or standard parameters (standard group; n=34 patients)...

Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy has emerged as one of the primary modalities of treatment of diffuse peritoneal malignancies. It is a complex surgical procedure with the patients facing major and potentially life threatening alterations of haemodynamic, respiratory, metabolic and thermal balance with significant fluid losses and the perioperative management is challenging for anaesthesiologists and intensive care physicians. Though the alterations are short lived, these patients require advanced organ function monitoring and support perioperatively...

BACKGROUND: During a previous study on intraoperative goal-directed haemodynamic treatment (GDHT) in elderly patients, cardiac performance did not improve as anticipated ( NCT01141894). We hypothesized that in this group, responsiveness to interventions could be predicted by individual patient characteristics. METHODS: Data for the present study were collected during a previously performed, single-centre, open, randomized, and controlled parallel-group superiority trial in patients aged ≥70 yr undergoing hip-fracture surgery...

BACKGROUND: Proximal femoral fracture (PFF) is a common orthopaedic emergency that affects mainly elderly people at high risk of complications. Advanced methods for managing fluid therapy during treatment for PFF are available, but their role in reducing risk is unclear. OBJECTIVES: To compare the safety and effectiveness of the following methods of perioperative fluid optimization in adult participants undergoing surgical repair of hip fracture: advanced invasive haemodynamic monitoring, such as transoesophageal Doppler and pulse contour analysis; a protocol using standard measures, such as blood pressure, urine output and central venous pressure; and usual care...

BACKGROUND AND AIMS: Scalp blocks combined with general anaesthesia reduce pin and incision response, along with providing stable perioperative haemodynamics and analgesia. Clonidine has proved to be a valuable additive in infiltrative blocks. We studied the efficacy and safety of addition of clonidine 2 μg/kg to scalp block with 0.25% bupivacaine (Group B) versus plain 0.25% bupivacaine (Group A) for supratentorial craniotomies. METHODS: Sixty patients were randomly divided into two groups to receive scalp block: Group A (with 0...

Haemodynamic monitoring is a vital part of daily practice in anaesthesia and intensive care. Although there is evidence to suggest that goal-directed therapy may improve outcomes in the perioperative period, which haemodynamic targets we should aim at to optimise patient outcomes remain elusive and controversial. This review highlights the pitfalls in commonly used haemodynamic targets, including arterial blood pressure, central venous pressure, cardiac output, central venous oxygen saturation and dynamic haemodynamic indices...

OBJECTIVE: Since stroke and myocardial ischaemia are major causes of perioperative morbidity and mortality associated with carotid endarterectomy, monitoring the brain and ensuring the best haemodynamic stability are important goals of the management. As regional anaesthesia was reported to improve haemodynamic stability during carotid endarterectomy (CEA), we conducted a prospective observational study on the efficacy and safety of ultrasound-guided intermediate cervical plexus blocks (CPB), with early (immediate postoperative) and mid-term (day 30) outcomes in awake patients undergoing CEA...

BACKGROUND: Transcatheter aortic valve implantation (TAVI) is a treatment strategy for patients with severe aortic stenosis. Although general anaesthesia (TAVI-GA) and sedation (TAVI-S) have previously been described for TAVI, the difference in safety and efficacy of both methods has not been studied in a randomized trial. METHODS: The INSERT trial was a single centre, controlled parallel-group trial with balanced randomization. Sixty-six patients (68-94 yr) with acquired aortic stenosis undergoing transfemoral CoreValve™ were assigned to TAVI-GA or TAVI-S...

BACKGROUND AND AIMS: Rapid recovery is desirable after neurosurgery as it enables early post-operative neurological evaluation and prompt management of complications. Studies have been rare comparing the recovery characteristics in paediatric neurosurgical patients. Hence, this study was carried out to compare the effect of sevoflurane and desflurane anaesthesia on emergence and extubation in children undergoing spinal surgery. METHODS: Sixty children, aged 1-12 years, undergoing elective surgery for lumbo-sacral spinal dysraphism were enrolled...

PURPOSE OF REVIEW: The aim of this study was to review recent advances and evidence for the use of cardiac output monitors to guide perioperative haemodynamic therapy. RECENT FINDINGS: There are multiple different cardiac output monitoring devices available for clinical use which are coupled with many different intervention protocols to manipulate perioperative haemodynamics. There is little evidence to demonstrate superiority of any one device. Previous small studies and meta-analyses have suggested that perioperative haemodynamic therapy guided by cardiac output monitoring improves outcomes after major surgery...
