... The correlation between increased IAP and intraoperative bleeding has been suspected anatomically and physiologically for quite some time. Some studies have looked at the effects of different positioning devices, Body Mass index (BMI), different modes of ventilation (pressure controlled versus volume controlled) on blood loss and IAP [1][2][3][4][5][6]. ...

... 4 In a 2020 randomised trial comparing bispectral index (BIS)guided sevoflurane and desflurane anaesthesia in obese patients, there was no difference in time to extubation (9.2 min vs 10 min for sevoflurane and desflurane, respectively, p>0.05); while patients in the sevoflurane group achieved baseline preoperative mini-mental state examination scores 11 min sooner than the desflurane group (40 min vs 51 min, p=0.001). 5 Comparing postoperative outcomes, a 2020 randomised trial comparing short-acting anaesthetic agents (desflurane-remifentanil combination) and standard agents (sevoflurane-fentanyl combination) did not find a significant difference in postoperative apnoea-hypopnoea index scores up to the third postoperative night. 6 More than 80% of patients in both groups had a formal diagnosis of obstructive sleep apnoea, based on the preoperative polysomnography apnoea-hypopnoea index. ...

... This implies that the duration of analgesia during the postoperative period was comparatively both clinically and statistically better in the nalbuphine group in comparison with the fentanyl group. Similar results were obtained by Garg et al. [12] and Gupta et al. [13] who inferred that the mean time for the first rescue analgesic request in the nalbuphine group was significantly better when compared to the fentanyl group. However, there were a few divergences from our observations from Srinivasaiah et al. [14] and Gomaa et al. [15] who found no significant difference in the duration of analgesia between nalbuphine and fentanyl. ...

... All subjects were adults, and three [10][11][12] of the studies included only elderly [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25] , both loading doses and maintenance doses were administrated. In four studies [26][27][28][29] , only maintenance doses were given. Three studies [10][11]30] included multiple Dex intervention groups, involving different dosages and administration regimens. ...

... Chuttani et al. [7] in their prospective study, 60 labouring parturient were randomly allocated into two equal groups to receive either of 0.1% Levobupivacaine and Fentanyl or 0.1% Ropivacaine and Fentanyl as epidural solutions. The incidence of instrumental deliveries were found to be 43.3% in the Levobupivacaine group and 30% in the Ropivacaine group. ...

... The goal is to provide targeted analgesia at the surgical site, thereby reducing pain intensity and improving patient comfort during the immediate postoperative period. [24,25] Dosages of dexmedetomidine used in wound infiltration vary based on factors such as the type of surgery, the extent of tissue trauma, and the desired duration of analgesia. Typically, concentrations ranging from 1 to 10 micrograms per millilitre are employed, often mixed with local anesthetic solutions like bupivacaine or lidocaine. ...

... A ventilação por pressão de suporte (PSV) é um modo ventilatório espontâneo, comumente utilizado para desmame de paciente em VMI, faz uso de uma pressão predefinida e constante para todo o esforço inspiratório realizado pelo paciente e tem a sua ciclagem a fluxo (Gautam et al., 2016). ...

... Konsentrasi plasma ini dapat dicapai dengan infus kontinyu dengan dosis 3-4 µg/kg/menit setelah bolus awal dan 14 µg/kg/menit tanpa dosis awal. 10 Kombinasi klonidin dan ketamin memiliki efek sinergis pada pasca operasi analgesia sehingga skor VAS pada kelompok T yang menerima kedua obat lebih rendah. Konsumsi morfin dihitung dengan melihat konsumsi total morfin yang tercatat di mesin PCA. ...

... 5-8 Relevant reports indicate that the implementation of wound infiltration with magnesium sulfate and ropivacaine mixture seems to reduce postoperative tramadol requirements after radical prostatectomy. [5][6][7][8] To the authors' knowledge, no studies investigating the use of magnesium sulfate as an adjunct to local anesthetics for wound infiltration thyroidectomy/parathyroidectomy exist in the current literature. Thus the present study aims to evaluate the effectiveness of wound infiltration with ropivacaine plus magnesium sulfate mixture in the management of postoperative pain in patients undergoing thyroid or parathyroid surgery with the safety of this practice constituting the secondary study end-point. ...

... (Bernat et al., 2003) found that the sensory block reached level T 4 in patients who received intrathecal 13mg hyperbaric bupivacaine 0.5 % + 15 µg fentanyl. (Bernat et al., 2007) (Grewal et al., 2003) also found T 4 were the highest dermatome level achieved in their study. ...
