Impact of Preoperative Anxiety in Patients on Hemodynamic Changes and a Dose of Anesthetic During Induction of Anesthesia

Abstract

Objectives:Each surgical patient is preoperatively, intraoperatively and postoperatively exposed to stress. The aim of this study was to determine the existence of preoperative anxiety, and to determine its impact on hemodynamic parameters (blood pressure, heart rate) in patients and dose of anesthetics during induction of anesthesia.Methods:A prospective clinical study conducted at the Department of Anesthesiology and Reanimation and Surgery Clinic of University Clinical Center Tuzla (UCC) in the period May 2012. to January 2015. The 80 patients were analyzed which were planned for and done an elective cholecystectomy surgery or herniectomy surgical intervention. Preoperative anxiety was measured with the help of Spielberg test and evaluation of depth of anesthesia was performed with BIS monitoring.Results:The results showed that all patients had some degree of preoperative manifest anxiety. Average values of mean arterial pressure, preoperatively and after the induction of general anesthesia, differed for 15,4 mm/Hg, but were not observed significant association between Spielberg score and differences in blood pressure. Preoperative anxiety is a significant predictor of administered dose of anesthetic. Each additional score on Spielberg scale reduces the dose of anesthetic for 0,304 mg/kgTT.Conclusion:Adequate assessment of preoperative anxiety and undertaking of certain steps to reduce it can assist in accurately determining the required dosage of anesthetic for the introduction of general anesthesia.

Short-term memory impairment in patients undergoing general anesthesia and its contributing factors

“…Surgery and anesthesia bring significant degrees of stress to the patient, and the use of anesthetic drugs and hemodynamic fluctuations and other operating room (OR) events can affect the patient's memory status and, therefore, lead to patients' dissatisfaction. [ 15 ] This has led to extensive researches in patients undergoing nonneurologic surgeries. [ 16 ] Memory and learning are among the most complex and important behavioral processes, and as the spectrum of anesthetic worldwide use is expanding, knowledge about the effects of these drugs on the memory process is of particular importance.…”

Investigating the causes of patient anxiety at induction of anaesthesia: A mixed methods study

“…Patient-reported anxiety levels in our study were comparable with other studies such as Oldman et al (2004) who measured anxiety on the morning of surgery (mean STAI ≈33). However, Ahmetovic-Djug et al (2017) investigating preoperative anxiety found a higher mean STAI (53). Only 15% of our study population achieved high anxiety scores on the STAI; this is lower than reported anxiety in other perioperative studies where the incidence of anxiety ranges from 60 to 92% ( Perks et al 2009 ).…”

Perbandingan Efektivitas Penggunaan Vibration Anesthesia Device (VAD) dengan Krim Campuran Eutektik (EMLA) dalam Mengurangi Nyeri Pemasangan Peripheral Intravenous Catheter (PIVC)

“…Anas Alatas 1* , Irfan Meison Hardi 1 , Eddy Harijanto 1 Pemasangan Peripheral Intravenous Catheter (PIVC) merupakan salah satu prosedur invasif yang paling banyak dilakukan di rumah sakit dengan lebih dari 70% pasien rawat inap membutuhkan pemasangan infus selama masa perawatan. 1 Sebanyak 40% pasien dilakukan pemasangan PIVC sebagai akses pengambilan sampel darah, dan sebanyak 25% pasien dipasangan PIVC sebagai akses untuk terapi cairan di unit gawat darurat (UGD). Pemasangan PIVC pada pasien penting untuk berbagai intervensi terapeutik, seperti terapi cairan, penggantian elektrolit, terapi antibiotik, nutrisi parenteral, pemberian zat kontras, dan prosedur anestesia.…”
